5. Troubleshooting
If something isn't working as it should, before you try
anything else, check to see whether there is an update
available for One Commander.

Shortcut key isn't working
This could be because it's being intercepted by another app,which can be tricky to track down. Windows allows apps tolist the system-wide hotkeys currently in use, but refuses to
identify which applications are using them. A utility called
Ethervane ActiveHotkeys (portable), which may not be
supported any more, lists hotkeys currently in use by
Windows. Then, by closing down apps one by one you
should be able to identify the culprit.

Filename not accepted
The following characters are not permitted in Windows fle
names:<>:"/\|?*
More information on fle naming can be found here.

Some folders, e.g. C:\Users\<user name>\AppData,
not visible
Make sure that you've checked all the "Visibility" options in
Settings > View.

https://onecommander.com/help/5._Troubleshooting.html[2022-05-19 22:00:36]

5. Troubleshooting

OK, we get the irony: if you can't start the app, how can you
read this? Except that there is a copy of this manual at
OneCommander.com, which is presumably where you'rereading this now. Here are three approaches, starting withthe simplest and ending with a restart that involves losing
your settings.
Approach 1: The Main Window may be hidden of screen.
Try pressing Shift+F1 to bring it back into view.
If that doesn't work:
Approach 2: One Commander may be "frozen". Open the
Windows Task Manager, click on the Processes tab, andsearch for any entries for One Commander, either in theApps or Background Processes sections. If you fnd any,
select them and click the "End task" button at the bottom
right-hand corner of the Task Manager window, or right-clickon them and select "End task". Try starting One Commander.
If that doesn't work:
Approach 3: There may be a problem with One
Commander's main settings fle.
1. Find the Settings folder (e.g. C:\Users\<username>\OneCommander\Settings\).
2. Rename the fle "OneCommanderV3.json" to somethingelse, for example"OneCommanderV3.json.deactivated". This fle will berecreated when you get to Step 4.
3. Open the Windows Task Manager, click on theProcesses tab, and search for any entries for One
Commander, either in the Apps or Background
Processes sections. If you fnd any, select them andclick the "End task" button at the bottom right-handcorner of the Task Manager window, or right-click onthem and select "End task".
4. Try starting One Commander. If it works, great!
However, you'll need to go through your Settings again,
because they will have been reset to One
Commander's default values.

https://onecommander.com/help/5._Troubleshooting.html[2022-05-19 22:00:36]

5. Troubleshooting

Something is spamming your flesystem with flechanges errors
If a program is constantly changing many fles at once thebufer that holds flesystem changes may get full and One
Commander will miss changes on disk. It may also degrade
the life of your SSD (solid state drive). Go to Settings >Advanced for a utility that will help you identify theofending program.

When maximized on a two-screen display, theMain Window spreads slightly on to the second
screenThis is an unfortunate feature of the third party library that
renders the Main Window. The only fx available is to turn of
the Acrylic window efect in Settings > Theme, shut down the
program and restart.

Drag and drop not working with other programs
If you can't get another program to accept a fle dropped
when you've dragged it from One Commander, try selecting"Use old Drag & Drop system" in Settings > Advanced.

If none of that helped...
Please email support@onecommander.com or go to the
support forum at Google Groups.

Installing One Commander
V3
One Commander Version 3 comes in two forms, both of which
will be automatically updated as new versions become
available. The Store version is easier to install, but has a few
minor limitations. The Portable version does not have theselimitations, but takes a couple more steps to install.
Portable version: This is downloaded fromhttps:\\onecommander.com, and comes as a zip fle.
Unlike normal Windows programs, it can be installed inany folder of your choice, including on portable drives(e.g. USB drives). To install this version:
Download a zip fle from onecommander.com.
Right-click the zip fle and select "Properties". At thebottom of the General tab, under "Security", checkthe "Unblock" box:

Extract the contents of the zip fle in the usual manner tothe folder in which you want to store the program.
Create a shortcut for the fle OneCommander.exe: Rightclick on the fle OneCommander.exe and select "Create
shortcut". This creates the shortcut fle"OneCommander.exe - Shortcut.lnk", which, when you
double-click on it, runs One Commander.
Move the shortcut to any convenient location. For
example, you can put it on the Start Menu, at C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start

Menu.
Microsoft Store version: This is installed by the Store on
your computer and updated from there. It is mainly thesame as the Portable version, with the following
diferences:
The Settings fles are found at "C:\Users\<Username>\OneCommander".
It cannot run ActiveX controls, meaning that One
Commander's native Preview can't open certain fle
types (mainly Microsoft Ofce fles).
Upgrading from Version 2: If you want to re-use your Version
2 settings, go to Settings > Window and click on

Installing One Commander on morethan one computer
If you would like to move your settings to One Commander ona second computer:
1. Install One Commander on the second computer.
2. On a removable medium (e.g. a USB drive), make a copyof the frst computer's fle "OneCommanderV3.json",which you can fnd in the Settings folder.
3. On the second computer, locate the Settings folder andrename the fle "OneCommanderV3.json" to somethingelse, for example "OneCommanderV3.json.installation".
4. Copy/move the "OneCommanderV3.json" fle from yourfrst computer into the Settings folder on the second
computer.
This will move over your basic settings. Others, such as
Favorites and Tabs, can't be copied over because theyreference folders specifc to the frst computer.
If you have a Pro licence, you will need to contact
support@onecommander.com to arrange for the Pro licenceto be valid on the second computer.

Supports horizontal and vertical split of browser panes
Supports opening multiple windows
Uses default Windows dialogs for fle move/copy/delete
operations (Taskmaster will be reimplemented)

1. Opening One Commander
for the frst time
One Commander is a dual-pane fle manager, meaning that it
can simultaneously display either one or two independent
fle browsers within the same window. The browsers can beviewed either in the Standard Layout, with a navigation paneat the top and a detailed view of the current folder at thebottom, or in a more compact Columns Layout.
The frst time you open One Commander:
1. You'll be asked if you want to import Favorites fromOne Commander Version 2 (the Microsoft Store
version).
2. You'll be given the choice of which layout you'd prefer,
as well as which theme:

1. Opening One Commander for the first time

You can change these selections later whenever you wish.
You can switch between the two layouts using the "Layout"
buttonorat bottom left of the Main Window, or
make one browser collapse to give a single-browser view bydragging the divider separating the browsers.
When you frst launch One Commander in the Standard
Layout the Folder Columns are hidden. Click here for more.

Closing One Commander
Clicking on the(WindowClose) button at the top right of
the Main Window doesn't shut One Commander down; itjust closes the window so that you can re-open it quickly
when you need it, for example by pressing Win+Alt+O. You
can shut it down by clicking Ctrl+WindowClose. Click here fordetails.

2. The Main Window
The Main Window displays a sidebar and either one or two
browsers. When One Commander is opened for the frst
time, both browsers are visible with the theme and layout
you chose from the opening dialog box. The Folder Columns
are hidden to start with in the Standard Layout. You canreveal them by clicking the
button, to the right of thefolder path at the top of each browser:

or by dragging down the Navigation/Folder Pane Divider justunderneath the folder path (keep dragging until themessage "Expand more to show pane" disappears):

The browsers can be displayed in either Standard orColumns layouts. You can switch back and forth between
them as often as you like using the Layout Button (or)
at the bottom left of the Main window (in the Main Toolbar;
see next section on this page). When you do this, the only
thing that changes is the layout; the fles, folders, andsettings remain the same.

3. The Browsers and Layouts
The browsers are divided into three main panes (seescreenshots below):
Navigation Pane: Shows all attached and mapped
drives as a series of Miller columns that allow you tonavigate up and down the folder trees for each drive.
Current Folder Pane: Shows the contents of the folderthat is currently selected in the Navigation Pane.
Details Pane: Shows details of the folder or fle that iscurrently selected in the Current Folder Pane. If a fle isselected, this pane shows a preview of the contents ofthe fle if it can (not all fle types are supported).

Layouts
One Commander provides two layouts: Standard andColumns. You can see the diference by clicking on the/

buttons in the Main Toolbar. In brief, the Standard Layout
shows one or both Browsers side-by-side and a set of Folder
Columns at the top of the Browser with the Current Folder
below them, while the Columns Layout sets the Browsers
one above the other, with the Current Folder to the right, as
the fnal column in the Folder Column display. Path selection
is slightly diferent in each display, but other than that it isentirely a matter of personal preference as to which you use.

The Browsers
You can create multiple independent fle/folder views in eachhttps://onecommander.com/help/2._Quick_introductory_guide/3._The_Browsers_and_Layouts.html[2022-05-19 22:01:36]

3. The Browsers and Layoutsbrowser by adding tabs. Click on the
button to the rightof the Browser Tabs to create a new tab, which will be aclone of the current tab (i.e. the tab that currently has thefocus). Alternatively, you can also specify a particular path
for all new tabs in Settings > Other.
Tabs can be closed by clicking on the

button that appears
when you move the cursor over the tab, or by clicking MMB.
Once deleted, they can't be restored.

You can resize either browser by dragging their borders, or
the Browser Divider separating them. Some borders have adrag handle surrounded by arrows:. The draghandle isn't strictly speaking necessary; it serves as areminder that the divider can be dragged. The arrows jump
the divider to the end of its travel.
If you try to reduce the width of a browser below a certain
point it tells you that it's about to collapse, meaning that it's
about to disappear from view so that you see a singlebrowser view. You can restore the dual-browser view bydragging the border or Browser Divider back again (or use
the drag handle or arrow). The browser will be restored
exactly as it was before.
If the Main Window is too narrow to show both Browsers in
the Standard Layout, one Browser will be closed. It will be reopened if you make the Main Window wide enough.
You can create background images for the Folder Panes —click here for how to do it.

The Navigation Pane displays folders in columns:

You can navigate to a folder in any of the columns, including
the ones to the left of the Current Folder Column, using the:Mouse: Click on the folder. A new column displaying thecontents of that folder will appear to the right of the column
you clicked in (replacing what was there before, if thecolumn you clicked on wasn't the Current Folder Column).
Keyboard: You can move through the entire directory treeusing just four cursor keys. You can:move between panes, and between folders and fleswithin panes, using a combination of Tab and Cursor
Arrow keys (Shift+Tab to move in the opposite
direction), and Enter to open folders (this doesn't movethe keyboard focus to the folder within) or fles;

4. Folder columns

use left/right arrowss to move between folder columns.
The right arrow also opens the folder from the Current
Folder pane.
The easiest way of understanding how this works is to try it.
Files or folders selected using the keyboard are surrounded
by a box of "marching ants":

In the Columns Layout, the rightmost column is also theCurrent Folder Pane. Folders in this pane need to be doubleclicked to open (although you can set it to open with a singleclick in Settings > Other).
The columns to the left of the Current Folder Column
compress to allow you a good view of the Current Folder
Column. If they're compressed too much to give a clear viewof their contents, you can expand them by moving themouse cursor over them. You can change many features of
how this works in Settings > Columns, for example how
quickly the columns respond to the mouse movements, howmuch they expand, and so on. Alternatively, if you don't likethese animations, you can turn them of in Settings >Columns.

One Commander allows all the basic folder and fle
operations that you would expect:
Open folders or fles by double-clicking on them (youcan change this to a single click in Settings > Other) orpressing Enter.
Move/copy fles using
Mouse: Drag and drop between browsers or toand from other Windows apps (to copy, hold Ctrl
key down while dragging). Note that One
Commander drag and drop works a littlediferently from Windows File Explorer. Moving afle when you meant to copy it can cause a lot of
trouble, so be careful!
Dragging a fle or folder in One Commander
will always move it. To copy, you must always
hold the Ctrl key down.
One Commander attaches a label to the fle
or folder being dragged to tell you whether
it's being moved (red label) or copied (greenlabel).
Keyboard:
Cutting, copying, and pasting generally: Cut(Ctrl+X), Copy (Ctrl+C), and Paste (Ctrl+V)

right-clicking on a folder or fle.
Create new folders: click on the

Create a new fle from a template: click on the
button (or Ctrl+N); you can select from a number of
popular fle types to create a new fle of that type in thecurrent folder. You can create as many of your own
templates as you like; see here for more.
Filtering list of folders or fles: with the cursor in afolder column or folder pane, start typing the name of
the folder or fle; folders or fles not containing thestring of characters you've typed are fltered out, so it
also is a quick way of searching for a folder or fle in along list. At the top of the column or pane One
Commander records what you've typed; cancel theflter by clicking the "X" or pressing the Esc key:

You can have as many flters running concurrently as you
like.
Note that the Spacebar key can't be used for fltering,
because it's used for previewing the selected item:

6. Sidebar
The Sidebar is the centre of operations for One Commander.
It is divided into three main sections:

1. Drives
This lists the currently-attached and mapped drives. It can be
hidden by going to Settings > Window > uncheck Showdrives in Sidebar. The

button gives the following options:

Hide drives from the sidebar: hides the list of drives,
but keeps the box.
Refresh everything (F5; refreshes all folder displays tomake sure they're up to date).
Map network drive (mapped network drives will belabelled both with the destination folder in the mapped
drive and the network path in parentheses).

2. Favorites
One Commander allows you to identify as many favorite
folders as you like. They are arranged into groups in the
Sidebar. One Commander creates an initial group from a listof standard folders in your C:\Users\<username> folder, andyou can add as many groups as you like by clicking the "NewGroup" button. Here's an example of a Favorites Group:https://onecommander.com/help/2._Quick_introductory_guide/6._Sidebar.html[2022-05-19 22:01:58]

6. Sidebar

Favorite folders have two basic uses:
They act as bookmarks for folders you use often:
click on a favorite folder and it opens in thecurrently-selected browser, in the currentlyselected tab
MMB opens the path in a new tab in the currentlyselected browser
You can quickly move or copy fles or folders from abrowser to a favorite folder by dragging (to move), or
holding the Ctrl key down and dragging (to copy), thefle or folder from the browser and dropping it onto
one of the items in the Favorites Group. Note thatdragging a fle or folder to a favorites group does notcreate a new favorite; it just moves or copies thatfolder or fle to the chosen favorite.
Basic operations for favorites groups:
Add folder to group: Click the "+" button to the right of
the group's name.
Rearrange folders within group, move folders
between groups: Drag folders up and down withingroup or between groups.
Create aliases (alternative names) for folders ingroups: Right-click on folder name and select "Change
Alias".
Remove folders from groups: Right-click on folder
name and select "Remove Path from List".

which you'll fnd in Settings > Theme, which is also where
you can switch between them. You can edit them if you
don't mind editing .xaml fles.
You can give the themes an acrylic (translucent) efect bychecking the appropriate box in Settings > Theme, as well aschange the icons that One Commander uses as well as the

For many users, One Commander will do everything theywant as it comes out of the box, so to speak. But there aremany features that can be changed, and if there's something
about One Commander that doesn't quite give you what you
need, you'll probably fnd a way of fxing it in the Settings.
You'll fnd adjustable settings in two main places:
Settings, for changing One Commander as a whole
Changing fles view, for changing the display in the
Current Folder Pane
If that's not enough for you, there are more possibilities if
you look in the folders reached by clicking on the About
program button in the Main Toolbar and then the Settings
Location button. Do be careful, though: only mess with thesefles if you know what you're doing!

Commander's appearance
There is a lot you can do to One Commander's appearance
using its various Settings in particular by choosing adiferent Theme. But there's even more you can do if you
don't mind exploring further under One Commander'shood. You can lift the hood by going to the Themes folder,
C:\User\<User Name>\One Commander\Themes (for theMicrosoft Store version), or the folder in which the Portableversion is installed. You can reach this folder quickly byclicking

on the About Program and then the Settings
Location button at the bottom of the dialog. You can create
a new theme by adding a new folder here and creating theTheme material that you want.

ThemesOne Commander comes with a number of built-in Themes,
which can be found at Settings > Theme. There are the usual
light and dark themes, as well as some alternatives.
A Theme is a combination of File Icons, Folder Icons, aThumbnail (for the Settings > Theme dropdown) and an.xaml fle that controls One Commander's appearance. You
can get a sense of what can be customized by exploring the.xaml fles for the built-in Themes.
You can vary the icons in use by choosing various options
available in Settings > Theme.
Any Theme can be given an Acrylic (translucent) efect bychecking the appropriate box in Settings > Theme. You may

notice a performance hit if you check this box, though.
Health and Safety Warnings:
Always make a copy of a theme before you edit it,
and work with the copy, not the original. When One
Commander is updated, it will overwrite any changes inthe built-in themes.
It's probably safest not to edit the built-in Themefles unless you really know what you are doing, but
to do your experimenting on a Theme that you create
yourself. If you do get into a mess, help is available
here.

Creating new Theme
Easy: make a copy of one of the Themes folders, and workwith that.

Accent Color
You can change the color that fles take when the mousepasses over them or they are selected in Settings > Theme.
Depending on the theme, an Accent color will be usedon certain elements, such as Columns Pane border or
Tabs border.
In some themes, the Accent Color is part of the theme
itself and changing it is disabled (for example in Nordor Nortorn themes).

Copying/moving by Drag and Drop
The approach to dragging and dropping items used byWindows is a bit confusing: it behaves diferently dependingon whether you are dragging and dropping within or
between drives. One Commander's default method isslightly diferent but has the virtue of consistency:
Dragging without Ctrl key: One Commander always
moves the item, regardless of whether the move is
between drives or between folders within the same
drive.

Most of the File View Designer is self-explanatory, and theeasiest way of learning how to use it is to create a custom
fle view using the "Save as" button at the bottom of thewindow and experiment with it. You can see the efects ofchanges you make by clicking

near the top of thewindow and viewing the changes in the Edited view pane.
Specifc points:

String Format Column
This is for advanced use only. If it is left blank, all values in
the column are taken from One Commander's Settings. It
allows the user to go into great depth with customizing
formats. Examples that can be used include diferent date
and time formats (see https://docs.microsoft.com/enus/dotnet/standard/base-types/standard-date-and-timeformat-strings), for example the time in a specifc UTC zoneor showing milliseconds, months written in words in theuser's language, numbers formatted with commas, and soon.

Removal Order
When you make a Browser narrower, this setting determines
the order in which columns disappear from the display. You
can think of it as the reluctance of a particular column todisappear, where the higher the number the more reluctant
the column is to vanish. So in the example above, if you
shrink a Browser horizontally, Time is the frst column todisappear and Name is the last. You can verify the Removal
Order settings by clicking

and then moving theresizing handle in the Edited view pane to left and right.

Buttons across the bottom of the window
Load: Loads a File View Design fle (they all end in ".json")from the folder <Settings location>\Resources\FileDesigns.
Save: Saves current File View Design fle (i.e. the File View
Design shown in the Edited view line at the top of the File
View Designer window).
Save as: Saves current File View Design fle under a newname.
Apply to current folder-pane and close (without saving):
Applies the new File View to the current folder pane
temporarily; the next time this folder is viewed, the File View
will revert to the saved version.

You can change the way that fles and folders are displayedin the Folder Pane by changing the File View. One
Commander has a number of built-in File Views, which you

The File Views are listed by clicking the

button in the

Default: the basic fle view, showing for each item thename (with some metadata, such as the number ofpages in a .docx fle), "age" of the item (how long since
it was last modifed), date and time of last modifcation,
attributes, and size.
Name Only: displays just fle/folder names, with noother columns.
Powershell: Similar to Default, but with the columns ina diferent order (attributes, date, size, name).
Thumbnail Grid: Displays thumbnails in a grid; change
the size of the thumbnails by holding Ctrl and rotating

Folder Columns andNavigation PaneThe folder tree is displayed as a series of columns. A single
click on any folder in a column opens that folder in a newcolumn to its right. Columns that behave like this are known
as Miller columns, in which all of the columns that are partof the tree branches leading to the currently-open folder
remain visible. This makes it easier to see where thecurrently-open folder sits in the folder tree structure, and tonavigate to other branches in the tree.
One Commander adds two features to standard Miller
columns to make it easier to work with folder displays inwhich a lot of folder columns are visible (when you're
working with a folder that is a long way from the drive root):
As each new folder is opened, the columns to its leftshrink to give room for the contents of the current
folder to be easily read.
As the cursor moves over folders to the left of thecurrent folder (i.e. over its parent folders), the folders
under the cursor expand while the cursor is over themso their contents can be seen. The responsiveness andspeed of this expansion, as well as many other featuresof the column display, can be adjusted in Settings >Columns.
Not everyone likes columns to change width in this way. They
can be turned of in Settings > Columns.

Moving dividers
Many of the dividers (the grey borders that separatediferent panes) have short dotted lines and V-shaped
arrows, for example the Browser Divider:

Click and hold on the dotted line to move the divider(actually, you can click and hold anywhere along the divider'slength except on the arrows for the same result).
Click on an arrow to move the divider as far as it will go. For
example, clicking on a Browser Divider arrow hides theBrowser that's in the direction in which the arrow points.
Clicking on an arrow when the divider is at its limit of travel
restores the divider to its default position.

Memory management in
One Commander
One Commander is made in Microsoft's .NET framework,
which manages memory for One Commander. Windows
may let a program's memory footprint grow while theprogram is used but when Windows needs memory again, it
will compact the program memory and reclaim unused
resources.
One Commander caches icons so they are loaded faster the
next time they are needed in the program session. All
displayed fle properties are also cached while they are in
the list, so scrolling through large folders will use morememory, but the memory will be released once the user
opens another folder (at Windows' own schedule).
Each thumbnail in the fle list and displayed preview will takea chunk of memory. For example, a previewed 10-Megapixel
photo will take 10x3 Megabytes (3 as number of color
channels), even if the image is a compressed jpeg.
Tabs don’t take additional memory in One Commander.
If you choose to keep the program running in the
background on close (see the option in Settings > Window)
all windows, fle properties, previews and the rest will be
unloaded from memory, but the program will keep cachedicons and compiled code for a faster next start, while
minimizing RAM usage.

Most of One Commander's settings take the form ofcheckboxes or sliders, and are self-explanatory. In thissection we provide some additional explanations where they
are needed.
Sliders can be adjusted either with the mouse cursor, or byclicking on them and moving them with cursor keys. Cursor
keys can be helpful if the slider is a little laggy (whichhappens when One Commander is showing you the resultsof the change in real time, as for example in Settings >General > Item properties).
The settings are stored in folders at C:\Users\<username>\OneCommander\ for the Microsoft Store version, orin {OneCommanderFolder}\Settings for portable version.
They can be reached quickly by clicking on(Aboutprogram) in the Main Window and then clicking the Settings
Location button at the bottom of the dialog.
Some settings changes are applied immediately; others
require a program restart. You'll know you need to do thiswhen this appears at the bottom of the settings window:. If you make a change that
requires a restart, One Commander will ask whether you
want to restart the program now:

These settings really are intended to be used only if you haveto; most users will never go near them. They are explained
in detail in the tab, and they cover:Rendering: how the One Commander window isrendered (i.e. drawn)
Watcher issues: this refers to the way that One
Commander watches for changes in fles and folders,so that the fle and folder display is kept up to date.
You can edit the list of fles that are excluded fromwatching, or track down what might be causing the
problem if you encounter a "Something is spammingyour flesystem with fle changes errors" condition.
Check and notify when there is text on clipboard:
Stops One Commander notifying you when you returnto One Commander and there's text in the clipboard.
How One Commander deals with reparse points: If
you don't know what these are, then you don't need toworry about this setting.
Check and notify when there is text on clipboard:This refers to the notifcation that appears when you
return to One Commander and there is text in the
clipboard.
Fix Stylus lag: May help if you are experience lags in
response to stylus operations.
Use old Drag & Drop system: Turn on if some otherprograms don't accept drop operations from One
Commander (in other words, they stop accepting flesthat you are attempting to drop in them).

Use high-resolution scrolling: This setting allows

Register as a default fle manager: This completely
replaces Windows File Manager on your system. It's
currently experimental; only use it if you're
comfortable with making changes to the Windows
Registry (which you may need to do if something goes
wrong).
Register Win+E hotkey: This changes the action of
Win+E so that it opens One Commander if it's runningin the background, or starts One Commander if it's
shut down. It doesn't replace Windows File Explorer,
although because of a shortcoming in the way that
Windows receives the message, if you click on the
Windows File Manager icon in the Windows Taskbar it
launches One Commander. Windows File Explorer isstill available when it's launched in other ways (e.g.
from the Start menu or by double-clicking on a folder

These settings apply to Folder Columns.
Create new columns without animating: When it's of andyou click on a folder in the Current Folder Column, the newcolumn slides in from the right instead of appearing
instantaneously. The sliding speed is determined by the
global animation duration.
Column Pane alignment: Sets the alignment of folders in
the Folder Panes individually for Standard and Columns
layouts. You may not notice the efect of this setting unlessthe columns are reasonably wide.

Interaction
This refers to the interaction between cursor and columns.
One Commander's default is to make Folder Columns
expand when the cursor enters them and contract when it
leaves. Some users like this because it makes it easier toview columns when a great many are displayed (i.e. when
the Current Folder is a long way from the drive root); others
don't.
Expand Column when cursor enters it: For each Layout,turns on this behavior.

Advanced Settings
Don't be put of by the "Advanced" label; it simply indicatesthat these are settings that many users won't be interested
in using. They adjust things like how quickly columns expand
when the cursor enters them (both in milliseconds), how

long the expansion takes, what width of column One
Commander should apply the expansion to, and a numberof settings for column widths, and they're self-explanatory.
They're worth experimenting with: you may fnd that they
improve One Commander's usability considerably. For
example, shortening Expand delay and Expand duration(say, to 400 ms each) makes the column expansion andcontraction much more responsive. If the delays are too
short, the columns will expand when the cursor is moving
quickly over them, which could get annoying.
If you come up with a mixture of settings that you really like,please, as the note says at the bottom of the tab, share yourfndings with support@onecommander.com

This group contains a miscellany of useful settings, most ofwhich are self-explanatory. They afect:
On start: Tabs shown when One Commander starts up.
The path can be an absolute path you'd like opened
when a new window opens (e.g. D:\myFolder) or it canbe a Windows environmental variable enclosed in %(e.g. %USERPROFILE%). "%USERPROFILE%" is a
shorthand version of "C:\Users\<your account name>".
So, for example, if you put"%USERPROFILE%\Documents" in the lower "On start:"box, when you start One Commander it opens a tab foryour Documents folder (and, by implication, forgets thetabs that were open in your previous session).
Creating a tab should: What a new tab shows when
it's created. So, using the example in the previous
bullet point, if you set this to"%USERPROFILE%\Documents", every new tab you
create by clicking

at the end of the row of tabs
opens your Documents folder.
New tab should be placed: Where the new tab shouldbe placed in relation to the current tab — immediately
after the current tab, or at the right-hand end of thetabs.
Tabs and favorites should show: Whether tabs andfavorites should show the full path name or just thename of the folder. You can also change the "alias" —i.e. the name of favorites or tabs — by right-clicking
and selecting "Change alias".

Visibility
Show hidden fles and folders: This needs to be checked (orturned on with Ctrl+H) in order to see a number of special

Show system fles and folders: Turn this of to avoid
accidentally moving or deleting critical system fles.
Hide temporary fles: Hides temporary fles that cancontribute to the clutter of large folders.

Sorting
Sets the sorting defaults for folders that you haven't alreadychanged the sort order for. Once you do change the sortorder for a particular folder, One Commander remembersthat sort order, overriding the defaults.
Keep folders on top: You may prefer to have folders always
listed above fles ("folders on top"), and this sets the default
for doing so. It can be overridden using the

Sort folders by name always: This ensures that the sortorder of folders is unafected by any changes you make tothe sort order using any of the other columns.

File View is optimized for folders containing image fles. Thissetting checks folders for which you haven't already chosena File View Design to see whether they might look betterusing the Thumbs+Details File View. You can override One
Commander's choice by selecting another File View Designusing thebutton in the Folder Pane Toolbar.
Scrolling behavior:
Pixel: This mode supports high-resolution touchpads(you may need to set "Use high resolution scrolling" in
Settings > Advanced").
Item: Scrolling the fle display moves the list by full itemheight, and snaps to the next full item. It scrolls by the
number of lines set in the Windows System mousesettings. This means that if the cursor is hovering overa fle while you're scrolling, it steps so that it will always
be over a fle whenever you stop scrolling. It's betterfor slower machines or for accessibility reasons.
Show folder background image: Set this if you'd like tohave background images for folders.

5. Troubleshooting
If something isn't working as it should, before you try
anything else, check to see whether there is an update
available for One Commander.

Shortcut key isn't working
This could be because it's being intercepted by another app,which can be tricky to track down. Windows allows apps tolist the system-wide hotkeys currently in use, but refuses to
identify which applications are using them. A utility called
Ethervane ActiveHotkeys (portable), which may not be
supported any more, lists hotkeys currently in use by
Windows. Then, by closing down apps one by one you
should be able to identify the culprit.

Filename not accepted
The following characters are not permitted in Windows fle
names:<>:"/\|?*
More information on fle naming can be found here.

Some folders, e.g. C:\Users\<user name>\AppData,

Make sure that you've checked all the "Visibility" options in

One Commander won't start

https://onecommander.com/help/1._One_Commander_Version_3/..\5._Troubleshooting.html[2022-05-19 22:06:54]

5. Troubleshooting

OK, we get the irony: if you can't start the app, how can you
read this? Except that there is a copy of this manual at
OneCommander.com, which is presumably where you'rereading this now. Here are three approaches, starting withthe simplest and ending with a restart that involves losing
your settings.
Approach 1: The Main Window may be hidden of screen.
Try pressing Shift+F1 to bring it back into view.
If that doesn't work:
Approach 2: One Commander may be "frozen". Open the
Windows Task Manager, click on the Processes tab, andsearch for any entries for One Commander, either in theApps or Background Processes sections. If you fnd any,
select them and click the "End task" button at the bottom
right-hand corner of the Task Manager window, or right-clickon them and select "End task". Try starting One Commander.
If that doesn't work:
Approach 3: There may be a problem with One
Commander's main settings fle.
1. Find the Settings folder (e.g. C:\Users\<username>\OneCommander\Settings\).
2. Rename the fle "OneCommanderV3.json" to somethingelse, for example"OneCommanderV3.json.deactivated". This fle will berecreated when you get to Step 4.
3. Open the Windows Task Manager, click on theProcesses tab, and search for any entries for One
Commander, either in the Apps or Background
Processes sections. If you fnd any, select them andclick the "End task" button at the bottom right-handcorner of the Task Manager window, or right-click onthem and select "End task".
4. Try starting One Commander. If it works, great!
However, you'll need to go through your Settings again,
because they will have been reset to One
Commander's default values.

5. Troubleshooting

Something is spamming your flesystem with flechanges errors
If a program is constantly changing many fles at once thebufer that holds flesystem changes may get full and One
Commander will miss changes on disk. It may also degrade
the life of your SSD (solid state drive). Go to Settings >Advanced for a utility that will help you identify theofending program.

When maximized on a two-screen display, theMain Window spreads slightly on to the second
screenThis is an unfortunate feature of the third party library that
renders the Main Window. The only fx available is to turn of
the Acrylic window efect in Settings > Theme, shut down the
program and restart.

Drag and drop not working with other programs
If you can't get another program to accept a fle dropped
when you've dragged it from One Commander, try selecting"Use old Drag & Drop system" in Settings > Advanced.

If none of that helped...
Please email support@onecommander.com or go to the
support forum at Google Groups.

3. The Browsers and Layouts
The browsers are divided into three main panes (seescreenshots below):
Navigation Pane: Shows all attached and mapped
drives as a series of Miller columns that allow you tonavigate up and down the folder trees for each drive.
Current Folder Pane: Shows the contents of the folderthat is currently selected in the Navigation Pane.
Details Pane: Shows details of the folder or fle that iscurrently selected in the Current Folder Pane. If a fle isselected, this pane shows a preview of the contents ofthe fle if it can (not all fle types are supported).

Layouts
One Commander provides two layouts: Standard andColumns. You can see the diference by clicking on the/

buttons in the Main Toolbar. In brief, the Standard Layout
shows one or both Browsers side-by-side and a set of Folder
Columns at the top of the Browser with the Current Folder
below them, while the Columns Layout sets the Browsers
one above the other, with the Current Folder to the right, as
the fnal column in the Folder Column display. Path selection
is slightly diferent in each display, but other than that it isentirely a matter of personal preference as to which you use.

The Browsers
You can create multiple independent fle/folder views in eachhttps://onecommander.com/help/1._One_Commander_Version_3/..\2._Quick_introductory_guide\3._The_Browsers_and_Layouts.html[2022-05-19 22:07:09]

3. The Browsers and Layoutsbrowser by adding tabs. Click on the
button to the rightof the Browser Tabs to create a new tab, which will be aclone of the current tab (i.e. the tab that currently has thefocus). Alternatively, you can also specify a particular path
for all new tabs in Settings > Other.
Tabs can be closed by clicking on the

button that appears
when you move the cursor over the tab, or by clicking MMB.
Once deleted, they can't be restored.

You can resize either browser by dragging their borders, or
the Browser Divider separating them. Some borders have adrag handle surrounded by arrows:. The draghandle isn't strictly speaking necessary; it serves as areminder that the divider can be dragged. The arrows jump
the divider to the end of its travel.
If you try to reduce the width of a browser below a certain
point it tells you that it's about to collapse, meaning that it's
about to disappear from view so that you see a singlebrowser view. You can restore the dual-browser view bydragging the border or Browser Divider back again (or use
the drag handle or arrow). The browser will be restored
exactly as it was before.
If the Main Window is too narrow to show both Browsers in
the Standard Layout, one Browser will be closed. It will be reopened if you make the Main Window wide enough.
You can create background images for the Folder Panes —click here for how to do it.

6. Sidebar
The Sidebar is the centre of operations for One Commander.
It is divided into three main sections:

1. Drives
This lists the currently-attached and mapped drives. It can be
hidden by going to Settings > Window > uncheck Showdrives in Sidebar. The

button gives the following options:

Hide drives from the sidebar: hides the list of drives,
but keeps the box.
Refresh everything (F5; refreshes all folder displays tomake sure they're up to date).
Map network drive (mapped network drives will belabelled both with the destination folder in the mapped
drive and the network path in parentheses).

2. Favorites
One Commander allows you to identify as many favorite
folders as you like. They are arranged into groups in the
Sidebar. One Commander creates an initial group from a listof standard folders in your C:\Users\<username> folder, andyou can add as many groups as you like by clicking the "NewGroup" button. Here's an example of a Favorites Group:https://onecommander.com/help/1._One_Commander_Version_3/..\2._Quick_introductory_guide\6._Sidebar.html[2022-05-19 22:07:17]

6. Sidebar

Favorite folders have two basic uses:
They act as bookmarks for folders you use often:
click on a favorite folder and it opens in thecurrently-selected browser, in the currentlyselected tab
MMB opens the path in a new tab in the currentlyselected browser
You can quickly move or copy fles or folders from abrowser to a favorite folder by dragging (to move), or
holding the Ctrl key down and dragging (to copy), thefle or folder from the browser and dropping it onto
one of the items in the Favorites Group. Note thatdragging a fle or folder to a favorites group does notcreate a new favorite; it just moves or copies thatfolder or fle to the chosen favorite.
Basic operations for favorites groups:
Add folder to group: Click the "+" button to the right of
the group's name.
Rearrange folders within group, move folders
between groups: Drag folders up and down withingroup or between groups.
Create aliases (alternative names) for folders ingroups: Right-click on folder name and select "Change
Alias".
Remove folders from groups: Right-click on folder
name and select "Remove Path from List".

Browser Tabs
Either Browser can have any number of Tabs, each with its
own Current Folder. So any instance of One Commander canhave a very large number of folders available to be selected
as Current Folders.
You can quickly change focus between Browsers with Alt+F,
and change the order of the Tabs by dragging them.

Tab Aliases
The Tab Alias is the name that appears on the Tab. By default
it is the name of the Tab's Current Folder, but you canchange this by selecting Change alias in the Tab's Context
Menu. You can change this default behavior in Settings >Other, to show the full path for the Tab.

Creating Tabs
Click thebutton to the right of the current set of
Tabs. The new Tab will be a clone of the Tab thatcurrently has the focus, unless you change thisbehaviour in Settings > Other. Alternatively, select the
Tab to be duplicated and press Ctrl+T.
Right-click any folder and select Open in... You have thechoice of opening that folder as a new Tab in the
Current Browser, the other Browser, or a new Window.

Moving/copying Tabs between
Browsers
Tabs can be moved to the other Browser (if open) using
Alt+MMB. Copying a Tab to the other Browser is a two-stepprocess: duplicate the Tab with Ctrl+T or clicking on the
button, then move the new Tab to the other Browsers with
Alt+MMB.

Closing Tabs
Click on the
button at the right-hand side of the Tab(which may not be visible if there are too many Tabs;
see next section), or
MMB

Large numbers of tabs
When you have a large number of Tabs, they shrink to be
narrow enough to accommodate all of them. This will
typically make them too narrow for the label text to bereadable, but their path will be displayed in a Tooltip:

When the cursor passes over narrow tabs, the Close Button
doesn't appear until you click on one of them. When you
do, the tab expands a little so that you can see both the tablabel and the

Button.

Copying/moving by Drag and Drop
The approach to dragging and dropping items used byWindows is a bit confusing: it behaves diferently dependingon whether you are dragging and dropping within or
between drives. One Commander's default method isslightly diferent but has the virtue of consistency:
Dragging without Ctrl key: One Commander always
moves the item, regardless of whether the move is
between drives or between folders within the same
drive.
Dragging with Ctrl key: One Commander always copies

One Commander can be started from the command line in a
Terminal window, using a number of switches. Switches areparameters entered after the name of the executible
program (here, OneCommander.exe), that afect the waythat the program behaves once launched.
Open a Terminal window, change the current folder in theCommand Line to the one in which OneCommander.exe islocated, and then use one of the following switches to start
One Commander (e.g. "OneCommander -nowindow"). In
each case, <path> must be the full pathname for the path
you want One Commander to open in, enclosed in quotes if
the path contains spaces, e.g. "C:\Users\<Username>\Documents".
At a particular path:onecommander.exe "C:\path"
To open in the same tab:
onecommander.exe -o "C:\path"
To open in a new tab:
onecommander.exe -o "C:\path" -newtab
To start One Commander with the Main Window inthe default position (the equivalent of starting One
Commander and pressing Shift+F1):

Pressing Win+Alt+O from any program: If you're using

Win+Alt+O (but not Ctrl+`) brings One Commander to yourcurrent desktop, or changes Virtual Desktops to the one on

no Main Window is currently open, then whichever setting
you choose, Win+Alt+O opens a One Commander window inyour current Virtual Desktop.
Use global hotkey Ctrl+' to show docked program

full-width and at the bottom half of the screen. Pressing it asecond time minimizes the window. Changing this setting
requires a program restart.
This simply makes Ctrl+` do the same thing as Win+Alt+O,

The Main Window displays a sidebar and either one or two
browsers. When One Commander is opened for the frst
time, both browsers are visible with the theme and layout
you chose from the opening dialog box. The Folder Columns
are hidden to start with in the Standard Layout. You canreveal them by clicking the
button, to the right of thefolder path at the top of each browser:

or by dragging down the Navigation/Folder Pane Divider justunderneath the folder path (keep dragging until themessage "Expand more to show pane" disappears):

The browsers can be displayed in either Standard orColumns layouts. You can switch back and forth between
them as often as you like using the Layout Button (or)
at the bottom left of the Main window (in the Main Toolbar;
see next section on this page). When you do this, the only
thing that changes is the layout; the fles, folders, andsettings remain the same.

Most of One Commander's settings take the form ofcheckboxes or sliders, and are self-explanatory. In thissection we provide some additional explanations where they
are needed.
Sliders can be adjusted either with the mouse cursor, or byclicking on them and moving them with cursor keys. Cursor
keys can be helpful if the slider is a little laggy (whichhappens when One Commander is showing you the resultsof the change in real time, as for example in Settings >General > Item properties).
The settings are stored in folders at C:\Users\<username>\OneCommander\ for the Microsoft Store version, orin {OneCommanderFolder}\Settings for portable version.
They can be reached quickly by clicking on(Aboutprogram) in the Main Window and then clicking the Settings
Location button at the bottom of the dialog.
Some settings changes are applied immediately; others
require a program restart. You'll know you need to do thiswhen this appears at the bottom of the settings window:. If you make a change that
requires a restart, One Commander will ask whether you
want to restart the program now:

These settings really are intended to be used only if you haveto; most users will never go near them. They are explained
in detail in the tab, and they cover:Rendering: how the One Commander window isrendered (i.e. drawn)
Watcher issues: this refers to the way that One
Commander watches for changes in fles and folders,so that the fle and folder display is kept up to date.
You can edit the list of fles that are excluded fromwatching, or track down what might be causing the
problem if you encounter a "Something is spammingyour flesystem with fle changes errors" condition.
Check and notify when there is text on clipboard:
Stops One Commander notifying you when you returnto One Commander and there's text in the clipboard.
How One Commander deals with reparse points: If
you don't know what these are, then you don't need toworry about this setting.
Check and notify when there is text on clipboard:This refers to the notifcation that appears when you
return to One Commander and there is text in the
clipboard.
Fix Stylus lag: May help if you are experience lags in
response to stylus operations.
Use old Drag & Drop system: Turn on if some otherprograms don't accept drop operations from One
Commander (in other words, they stop accepting flesthat you are attempting to drop in them).

Use high-resolution scrolling: This setting allows
smooth scrolling for high-resolution touchpads.
Register as a default fle manager: This completely
replaces Windows File Manager on your system. It's
currently experimental; only use it if you're
comfortable with making changes to the Windows
Registry (which you may need to do if something goes
wrong).
Register Win+E hotkey: This changes the action of
Win+E so that it opens One Commander if it's runningin the background, or starts One Commander if it's
shut down. It doesn't replace Windows File Explorer,
although because of a shortcoming in the way that
Windows receives the message, if you click on the
Windows File Manager icon in the Windows Taskbar it
launches One Commander. Windows File Explorer isstill available when it's launched in other ways (e.g.
from the Start menu or by double-clicking on a folder
on the Windows desktop).

If something isn't working as it should, before you try
anything else, check to see whether there is an update
available for One Commander.

Shortcut key isn't working
This could be because it's being intercepted by another app,which can be tricky to track down. Windows allows apps tolist the system-wide hotkeys currently in use, but refuses to
identify which applications are using them. A utility called
Ethervane ActiveHotkeys (portable), which may not be
supported any more, lists hotkeys currently in use by
Windows. Then, by closing down apps one by one you
should be able to identify the culprit.

Filename not accepted
The following characters are not permitted in Windows fle
names:<>:"/\|?*
More information on fle naming can be found here.

5. Troubleshooting

OK, we get the irony: if you can't start the app, how can you
read this? Except that there is a copy of this manual at
OneCommander.com, which is presumably where you'rereading this now. Here are three approaches, starting withthe simplest and ending with a restart that involves losing
your settings.
Approach 1: The Main Window may be hidden of screen.
Try pressing Shift+F1 to bring it back into view.
If that doesn't work:
Approach 2: One Commander may be "frozen". Open the
Windows Task Manager, click on the Processes tab, andsearch for any entries for One Commander, either in theApps or Background Processes sections. If you fnd any,
select them and click the "End task" button at the bottom
right-hand corner of the Task Manager window, or right-clickon them and select "End task". Try starting One Commander.
If that doesn't work:
Approach 3: There may be a problem with One
Commander's main settings fle.
1. Find the Settings folder (e.g. C:\Users\<username>\OneCommander\Settings\).
2. Rename the fle "OneCommanderV3.json" to somethingelse, for example"OneCommanderV3.json.deactivated". This fle will berecreated when you get to Step 4.
3. Open the Windows Task Manager, click on theProcesses tab, and search for any entries for One
Commander, either in the Apps or Background
Processes sections. If you fnd any, select them andclick the "End task" button at the bottom right-handcorner of the Task Manager window, or right-click onthem and select "End task".
4. Try starting One Commander. If it works, great!
However, you'll need to go through your Settings again,
because they will have been reset to One
Commander's default values.

5. Troubleshooting

Something is spamming your flesystem with flechanges errors
If a program is constantly changing many fles at once thebufer that holds flesystem changes may get full and One
Commander will miss changes on disk. It may also degrade
the life of your SSD (solid state drive). Go to Settings >Advanced for a utility that will help you identify theofending program.

When maximized on a two-screen display, theMain Window spreads slightly on to the second
screenThis is an unfortunate feature of the third party library that
renders the Main Window. The only fx available is to turn of
the Acrylic window efect in Settings > Theme, shut down the
program and restart.

Drag and drop not working with other programs
If you can't get another program to accept a fle dropped
when you've dragged it from One Commander, try selecting"Use old Drag & Drop system" in Settings > Advanced.

If none of that helped...
Please email support@onecommander.com or go to the
support forum at Google Groups.

program (here, OneCommander.exe), that afect the waythat the program behaves once launched.
Open a Terminal window, change the current folder in theCommand Line to the one in which OneCommander.exe islocated, and then use one of the following switches to start
One Commander (e.g. "OneCommander -nowindow"). In
each case, <path> must be the full pathname for the path
you want One Commander to open in, enclosed in quotes if
the path contains spaces, e.g. "C:\Users\<Username>\Documents".
At a particular path:onecommander.exe "C:\path"
To open in the same tab:
onecommander.exe -o "C:\path"
To open in a new tab:
onecommander.exe -o "C:\path" -newtab
To start One Commander with the Main Window inthe default position (the equivalent of starting One
Commander and pressing Shift+F1):

Click and hold on the dotted line to move the divider(actually, you can click and hold anywhere along the divider'slength except on the arrows for the same result).
Click on an arrow to move the divider as far as it will go. For
example, clicking on a Browser Divider arrow hides theBrowser that's in the direction in which the arrow points.
Clicking on an arrow when the divider is at its limit of travel
restores the divider to its default position.

Settings
Most of One Commander's settings take the form ofcheckboxes or sliders, and are self-explanatory. In thissection we provide some additional explanations where they
are needed.
Sliders can be adjusted either with the mouse cursor, or byclicking on them and moving them with cursor keys. Cursor
keys can be helpful if the slider is a little laggy (whichhappens when One Commander is showing you the resultsof the change in real time, as for example in Settings >General > Item properties).
The settings are stored in folders at C:\Users\<username>\OneCommander\ for the Microsoft Store version, orin {OneCommanderFolder}\Settings for portable version.
They can be reached quickly by clicking on(Aboutprogram) in the Main Window and then clicking the Settings
Location button at the bottom of the dialog.
Some settings changes are applied immediately; others
require a program restart. You'll know you need to do thiswhen this appears at the bottom of the settings window:. If you make a change that
requires a restart, One Commander will ask whether you
want to restart the program now:

Installing One Commander
V3
One Commander Version 3 comes in two forms, both of which
will be automatically updated as new versions become
available. The Store version is easier to install, but has a few
minor limitations. The Portable version does not have theselimitations, but takes a couple more steps to install.
Portable version: This is downloaded fromhttps:\\onecommander.com, and comes as a zip fle.
Unlike normal Windows programs, it can be installed inany folder of your choice, including on portable drives(e.g. USB drives). To install this version:
Download a zip fle from onecommander.com.
Right-click the zip fle and select "Properties". At thebottom of the General tab, under "Security", checkthe "Unblock" box:

Extract the contents of the zip fle in the usual manner tothe folder in which you want to store the program.
Create a shortcut for the fle OneCommander.exe: Rightclick on the fle OneCommander.exe and select "Create
shortcut". This creates the shortcut fle"OneCommander.exe - Shortcut.lnk", which, when you
double-click on it, runs One Commander.
Move the shortcut to any convenient location. For
example, you can put it on the Start Menu, at C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start

Microsoft Store version: This is installed by the Store on
your computer and updated from there. It is mainly thesame as the Portable version, with the following
diferences:
The Settings fles are found at "C:\Users\<Username>\OneCommander".
It cannot run ActiveX controls, meaning that One
Commander's native Preview can't open certain fle
types (mainly Microsoft Ofce fles).
Upgrading from Version 2: If you want to re-use your Version
2 settings, go to Settings > Window and click on

Installing One Commander on morethan one computer
If you would like to move your settings to One Commander ona second computer:
1. Install One Commander on the second computer.
2. On a removable medium (e.g. a USB drive), make a copyof the frst computer's fle "OneCommanderV3.json",which you can fnd in the Settings folder.
3. On the second computer, locate the Settings folder andrename the fle "OneCommanderV3.json" to somethingelse, for example "OneCommanderV3.json.installation".
4. Copy/move the "OneCommanderV3.json" fle from yourfrst computer into the Settings folder on the second
computer.
This will move over your basic settings. Others, such as
Favorites and Tabs, can't be copied over because theyreference folders specifc to the frst computer.
If you have a Pro licence, you will need to contact
support@onecommander.com to arrange for the Pro licenceto be valid on the second computer.

you don't know what these are, then you don't need toworry about this setting.
Check and notify when there is text on clipboard:This refers to the notifcation that appears when you
return to One Commander and there is text in the

Fix Stylus lag: May help if you are experience lags in
response to stylus operations.
Use old Drag & Drop system: Turn on if some otherprograms don't accept drop operations from One

currently experimental; only use it if you're
comfortable with making changes to the Windows

wrong).
Register Win+E hotkey: This changes the action of
Win+E so that it opens One Commander if it's runningin the background, or starts One Commander if it's
shut down. It doesn't replace Windows File Explorer,
although because of a shortcoming in the way that
Windows receives the message, if you click on the
Windows File Manager icon in the Windows Taskbar it
launches One Commander. Windows File Explorer isstill available when it's launched in other ways (e.g.
from the Start menu or by double-clicking on a folder

Folder Columns andNavigation PaneThe folder tree is displayed as a series of columns. A single
click on any folder in a column opens that folder in a newcolumn to its right. Columns that behave like this are known
as Miller columns, in which all of the columns that are partof the tree branches leading to the currently-open folder
remain visible. This makes it easier to see where thecurrently-open folder sits in the folder tree structure, and tonavigate to other branches in the tree.
One Commander adds two features to standard Miller
columns to make it easier to work with folder displays inwhich a lot of folder columns are visible (when you're
working with a folder that is a long way from the drive root):
As each new folder is opened, the columns to its leftshrink to give room for the contents of the current
folder to be easily read.
As the cursor moves over folders to the left of thecurrent folder (i.e. over its parent folders), the folders
under the cursor expand while the cursor is over themso their contents can be seen. The responsiveness andspeed of this expansion, as well as many other featuresof the column display, can be adjusted in Settings >Columns.
Not everyone likes columns to change width in this way. They
can be turned of in Settings > Columns.

This group contains a miscellany of useful settings, most ofwhich are self-explanatory. They afect:
On start: Tabs shown when One Commander starts up.
The path can be an absolute path you'd like opened
when a new window opens (e.g. D:\myFolder) or it canbe a Windows environmental variable enclosed in %(e.g. %USERPROFILE%). "%USERPROFILE%" is a
shorthand version of "C:\Users\<your account name>".
So, for example, if you put"%USERPROFILE%\Documents" in the lower "On start:"box, when you start One Commander it opens a tab foryour Documents folder (and, by implication, forgets thetabs that were open in your previous session).
Creating a tab should: What a new tab shows when
it's created. So, using the example in the previous
bullet point, if you set this to"%USERPROFILE%\Documents", every new tab you
create by clicking

at the end of the row of tabs
opens your Documents folder.
New tab should be placed: Where the new tab shouldbe placed in relation to the current tab — immediately
after the current tab, or at the right-hand end of thetabs.
Tabs and favorites should show: Whether tabs andfavorites should show the full path name or just thename of the folder. You can also change the "alias" —i.e. the name of favorites or tabs — by right-clicking
and selecting "Change alias".

Large numbers of tabs
When you have a large number of Tabs, they shrink to be
narrow enough to accommodate all of them. This will
typically make them too narrow for the label text to bereadable, but their path will be displayed in a Tooltip:

When the cursor passes over narrow tabs, the Close Button
doesn't appear until you click on one of them. When you
do, the tab expands a little so that you can see both the tablabel and the

Columns
These settings apply to Folder Columns.
Create new columns without animating: When it's of andyou click on a folder in the Current Folder Column, the newcolumn slides in from the right instead of appearing
instantaneously. The sliding speed is determined by the
global animation duration.
Column Pane alignment: Sets the alignment of folders in
the Folder Panes individually for Standard and Columns
layouts. You may not notice the efect of this setting unlessthe columns are reasonably wide.

Interaction
This refers to the interaction between cursor and columns.
One Commander's default is to make Folder Columns
expand when the cursor enters them and contract when it
leaves. Some users like this because it makes it easier toview columns when a great many are displayed (i.e. when
the Current Folder is a long way from the drive root); others
don't.
Expand Column when cursor enters it: For each Layout,turns on this behavior.

Advanced Settings
Don't be put of by the "Advanced" label; it simply indicatesthat these are settings that many users won't be interested
in using. They adjust things like how quickly columns expand
when the cursor enters them (both in milliseconds), how

long the expansion takes, what width of column One
Commander should apply the expansion to, and a numberof settings for column widths, and they're self-explanatory.
They're worth experimenting with: you may fnd that they
improve One Commander's usability considerably. For
example, shortening Expand delay and Expand duration(say, to 400 ms each) makes the column expansion andcontraction much more responsive. If the delays are too
short, the columns will expand when the cursor is moving
quickly over them, which could get annoying.
If you come up with a mixture of settings that you really like,please, as the note says at the bottom of the tab, share yourfndings with support@onecommander.com

moves the item, regardless of whether the move is
between drives or between folders within the same

Templates for creating fles

documents, spreadsheets, text fles — you can create a
Template (a blank fle of that fle type) for that fle type. Then
when you need to create a fle of this type, navigate to thefolder that will hold the fle and click theicon in the
Folder Pane Toolbar or press Ctrl+N. This pops up your listof Templates:

Select the Template you need, fll in the File name, and thenclick either of the buttons at the bottom of the pop-up. The
new fle is created in the current folder (and opened if you
click "...and open").

The fle that's created from the Template will have theproperties of the Template fle in the Templates folder, forexample in Microsoft Word the default settings for font,styles etc. Make sure that the Template for that fle type has
all the default settings that you want, otherwise you'll haveto change them to your individual preferences every time

it will, however, show an image preview if there is one

Most of the File View Designer is self-explanatory, and theeasiest way of learning how to use it is to create a custom
fle view using the "Save as" button at the bottom of thewindow and experiment with it. You can see the efects ofchanges you make by clicking

near the top of thewindow and viewing the changes in the Edited view pane.
Specifc points:

String Format Column
This is for advanced use only. If it is left blank, all values in
the column are taken from One Commander's Settings. It
allows the user to go into great depth with customizing
formats. Examples that can be used include diferent date
and time formats (see https://docs.microsoft.com/enus/dotnet/standard/base-types/standard-date-and-timeformat-strings), for example the time in a specifc UTC zoneor showing milliseconds, months written in words in theuser's language, numbers formatted with commas, and soon.

Removal Order
When you make a Browser narrower, this setting determines
the order in which columns disappear from the display. You
can think of it as the reluctance of a particular column todisappear, where the higher the number the more reluctant
the column is to vanish. So in the example above, if you
shrink a Browser horizontally, Time is the frst column todisappear and Name is the last. You can verify the Removal
Order settings by clicking

and then moving theresizing handle in the Edited view pane to left and right.

Buttons across the bottom of the window
Load: Loads a File View Design fle (they all end in ".json")from the folder <Settings location>\Resources\FileDesigns.
Save: Saves current File View Design fle (i.e. the File View
Design shown in the Edited view line at the top of the File
View Designer window).
Save as: Saves current File View Design fle under a newname.
Apply to current folder-pane and close (without saving):
Applies the new File View to the current folder pane
temporarily; the next time this folder is viewed, the File View
will revert to the saved version.

Commander's appearance
There is a lot you can do to One Commander's appearance
using its various Settings in particular by choosing adiferent Theme. But there's even more you can do if you
don't mind exploring further under One Commander'shood. You can lift the hood by going to the Themes folder,
C:\User\<User Name>\One Commander\Themes (for theMicrosoft Store version), or the folder in which the Portableversion is installed. You can reach this folder quickly byclicking

on the About Program and then the Settings
Location button at the bottom of the dialog. You can create
a new theme by adding a new folder here and creating theTheme material that you want.

ThemesOne Commander comes with a number of built-in Themes,
which can be found at Settings > Theme. There are the usual
light and dark themes, as well as some alternatives.
A Theme is a combination of File Icons, Folder Icons, aThumbnail (for the Settings > Theme dropdown) and an.xaml fle that controls One Commander's appearance. You
can get a sense of what can be customized by exploring the.xaml fles for the built-in Themes.
You can vary the icons in use by choosing various options
available in Settings > Theme.
Any Theme can be given an Acrylic (translucent) efect bychecking the appropriate box in Settings > Theme. You may

notice a performance hit if you check this box, though.
Health and Safety Warnings:
Always make a copy of a theme before you edit it,
and work with the copy, not the original. When One
Commander is updated, it will overwrite any changes inthe built-in themes.
It's probably safest not to edit the built-in Themefles unless you really know what you are doing, but
to do your experimenting on a Theme that you create
yourself. If you do get into a mess, help is available
here.

Creating new Theme
Easy: make a copy of one of the Themes folders, and workwith that.

Accent Color
You can change the color that fles take when the mousepasses over them or they are selected in Settings > Theme.
Depending on the theme, an Accent color will be usedon certain elements, such as Columns Pane border or
Tabs border.
In some themes, the Accent Color is part of the theme
itself and changing it is disabled (for example in Nordor Nortorn themes).

2. The Main Window
The Main Window displays a sidebar and either one or two
browsers. When One Commander is opened for the frst
time, both browsers are visible with the theme and layout
you chose from the opening dialog box. The Folder Columns
are hidden to start with in the Standard Layout. You canreveal them by clicking the
button, to the right of thefolder path at the top of each browser:

or by dragging down the Navigation/Folder Pane Divider justunderneath the folder path (keep dragging until themessage "Expand more to show pane" disappears):

The browsers can be displayed in either Standard orColumns layouts. You can switch back and forth between
them as often as you like using the Layout Button (or)
at the bottom left of the Main window (in the Main Toolbar;
see next section on this page). When you do this, the only
thing that changes is the layout; the fles, folders, andsettings remain the same.

5. Troubleshooting
If something isn't working as it should, before you try
anything else, check to see whether there is an update
available for One Commander.

Shortcut key isn't working
This could be because it's being intercepted by another app,which can be tricky to track down. Windows allows apps tolist the system-wide hotkeys currently in use, but refuses to
identify which applications are using them. A utility called
Ethervane ActiveHotkeys (portable), which may not be
supported any more, lists hotkeys currently in use by
Windows. Then, by closing down apps one by one you
should be able to identify the culprit.

Filename not accepted
The following characters are not permitted in Windows fle
names:<>:"/\|?*
More information on fle naming can be found here.

Some folders, e.g. C:\Users\<user name>\AppData,

5. Troubleshooting

OK, we get the irony: if you can't start the app, how can you
read this? Except that there is a copy of this manual at
OneCommander.com, which is presumably where you'rereading this now. Here are three approaches, starting withthe simplest and ending with a restart that involves losing
your settings.
Approach 1: The Main Window may be hidden of screen.
Try pressing Shift+F1 to bring it back into view.
If that doesn't work:
Approach 2: One Commander may be "frozen". Open the
Windows Task Manager, click on the Processes tab, andsearch for any entries for One Commander, either in theApps or Background Processes sections. If you fnd any,
select them and click the "End task" button at the bottom
right-hand corner of the Task Manager window, or right-clickon them and select "End task". Try starting One Commander.
If that doesn't work:
Approach 3: There may be a problem with One
Commander's main settings fle.
1. Find the Settings folder (e.g. C:\Users\<username>\OneCommander\Settings\).
2. Rename the fle "OneCommanderV3.json" to somethingelse, for example"OneCommanderV3.json.deactivated". This fle will berecreated when you get to Step 4.
3. Open the Windows Task Manager, click on theProcesses tab, and search for any entries for One
Commander, either in the Apps or Background
Processes sections. If you fnd any, select them andclick the "End task" button at the bottom right-handcorner of the Task Manager window, or right-click onthem and select "End task".
4. Try starting One Commander. If it works, great!
However, you'll need to go through your Settings again,
because they will have been reset to One
Commander's default values.

5. Troubleshooting

Something is spamming your flesystem with flechanges errors
If a program is constantly changing many fles at once thebufer that holds flesystem changes may get full and One
Commander will miss changes on disk. It may also degrade
the life of your SSD (solid state drive). Go to Settings >Advanced for a utility that will help you identify theofending program.

When maximized on a two-screen display, theMain Window spreads slightly on to the second
screenThis is an unfortunate feature of the third party library that
renders the Main Window. The only fx available is to turn of
the Acrylic window efect in Settings > Theme, shut down the
program and restart.

Drag and drop not working with other programs
If you can't get another program to accept a fle dropped
when you've dragged it from One Commander, try selecting"Use old Drag & Drop system" in Settings > Advanced.

If none of that helped...
Please email support@onecommander.com or go to the
support forum at Google Groups.

For many users, One Commander will do everything theywant as it comes out of the box, so to speak. But there aremany features that can be changed, and if there's something
about One Commander that doesn't quite give you what you
need, you'll probably fnd a way of fxing it in the Settings.
You'll fnd adjustable settings in two main places:
Settings, for changing One Commander as a whole
Changing fles view, for changing the display in the
Current Folder Pane
If that's not enough for you, there are more possibilities if
you look in the folders reached by clicking on the About
program button in the Main Toolbar and then the Settings
Location button. Do be careful, though: only mess with thesefles if you know what you're doing!

Conventions andterminology used in thismanualContext Menu: The menu that pops up when you right-clickon something.
Key presses: "<name of key>+" means hold a particular socalled "modifer" key (Ctrl, Shift, Alt) down while pressing, which isanother, e.g. "Ctrl+C". "Win" is the Windows key
present on most keyboards, usually to the left of theSpacebar.
Mouse buttons: LMB = left mouse button; similarly, MMB
and RMB for middle and right mouse butttons. "Click"without any qualifcations means LMB click.
Path: Folders and fles are referred to generically as "paths",
a shorter version of "pathname", which specifes the paththe operating system must take to fnd a folder or fle.
Screenshots: Things to look for are highlighted in red, e.g.:

Settings Location: The folder in which One Commander'ssettings are stored. It can be reached from thebutton on
the Main Toolbar. It contains a number of sub-folders,
including the Settings Folder, which you'll need to access if
you want to move your settings to a copy of One
Commander on another second computer.
Terminal: The generic name for programs that provide
access to the Windows Command Line, for example CMD,

3. The Browsers and Layouts
The browsers are divided into three main panes (seescreenshots below):
Navigation Pane: Shows all attached and mapped
drives as a series of Miller columns that allow you tonavigate up and down the folder trees for each drive.
Current Folder Pane: Shows the contents of the folderthat is currently selected in the Navigation Pane.
Details Pane: Shows details of the folder or fle that iscurrently selected in the Current Folder Pane. If a fle isselected, this pane shows a preview of the contents ofthe fle if it can (not all fle types are supported).

Layouts
One Commander provides two layouts: Standard andColumns. You can see the diference by clicking on the/

buttons in the Main Toolbar. In brief, the Standard Layout
shows one or both Browsers side-by-side and a set of Folder
Columns at the top of the Browser with the Current Folder
below them, while the Columns Layout sets the Browsers
one above the other, with the Current Folder to the right, as
the fnal column in the Folder Column display. Path selection
is slightly diferent in each display, but other than that it isentirely a matter of personal preference as to which you use.

The Browsers
You can create multiple independent fle/folder views in eachhttps://onecommander.com/help/3._Full_reference_guide/..\2._Quick_introductory_guide\3._The_Browsers_and_Layouts.html[2022-05-19 22:13:28]

3. The Browsers and Layoutsbrowser by adding tabs. Click on the
button to the rightof the Browser Tabs to create a new tab, which will be aclone of the current tab (i.e. the tab that currently has thefocus). Alternatively, you can also specify a particular path
for all new tabs in Settings > Other.
Tabs can be closed by clicking on the

button that appears
when you move the cursor over the tab, or by clicking MMB.
Once deleted, they can't be restored.

You can resize either browser by dragging their borders, or
the Browser Divider separating them. Some borders have adrag handle surrounded by arrows:. The draghandle isn't strictly speaking necessary; it serves as areminder that the divider can be dragged. The arrows jump
the divider to the end of its travel.
If you try to reduce the width of a browser below a certain
point it tells you that it's about to collapse, meaning that it's
about to disappear from view so that you see a singlebrowser view. You can restore the dual-browser view bydragging the border or Browser Divider back again (or use
the drag handle or arrow). The browser will be restored
exactly as it was before.
If the Main Window is too narrow to show both Browsers in
the Standard Layout, one Browser will be closed. It will be reopened if you make the Main Window wide enough.
You can create background images for the Folder Panes —click here for how to do it.

6. Sidebar
The Sidebar is the centre of operations for One Commander.
It is divided into three main sections:

1. Drives
This lists the currently-attached and mapped drives. It can be
hidden by going to Settings > Window > uncheck Showdrives in Sidebar. The

button gives the following options:

Hide drives from the sidebar: hides the list of drives,
but keeps the box.
Refresh everything (F5; refreshes all folder displays tomake sure they're up to date).
Map network drive (mapped network drives will belabelled both with the destination folder in the mapped
drive and the network path in parentheses).

2. Favorites
One Commander allows you to identify as many favorite
folders as you like. They are arranged into groups in the
Sidebar. One Commander creates an initial group from a listof standard folders in your C:\Users\<username> folder, andyou can add as many groups as you like by clicking the "NewGroup" button. Here's an example of a Favorites Group:https://onecommander.com/help/3._Full_reference_guide/..\2._Quick_introductory_guide\6._Sidebar.html[2022-05-19 22:13:36]

6. Sidebar

Favorite folders have two basic uses:
They act as bookmarks for folders you use often:
click on a favorite folder and it opens in thecurrently-selected browser, in the currentlyselected tab
MMB opens the path in a new tab in the currentlyselected browser
You can quickly move or copy fles or folders from abrowser to a favorite folder by dragging (to move), or
holding the Ctrl key down and dragging (to copy), thefle or folder from the browser and dropping it onto
one of the items in the Favorites Group. Note thatdragging a fle or folder to a favorites group does notcreate a new favorite; it just moves or copies thatfolder or fle to the chosen favorite.
Basic operations for favorites groups:
Add folder to group: Click the "+" button to the right of
the group's name.
Rearrange folders within group, move folders
between groups: Drag folders up and down withingroup or between groups.
Create aliases (alternative names) for folders ingroups: Right-click on folder name and select "Change
Alias".
Remove folders from groups: Right-click on folder
name and select "Remove Path from List".

One Commander allows you to change themes — thecolours of the diferent components of the user interface,for example light or dark, and the icon packs it uses — andcreate new ones. It comes with a number of built-in themes,
which you'll fnd in Settings > Theme, which is also where
you can switch between them. You can edit them if you
don't mind editing .xaml fles.
You can give the themes an acrylic (translucent) efect bychecking the appropriate box in Settings > Theme, as well aschange the icons that One Commander uses as well as the
Accent Color (the color of items over which the mousemoves or that are selected).
More information about changing these themes or adding
new ones is here.

key down while dragging). Note that One
Commander drag and drop works a littlediferently from Windows File Explorer. Moving afle when you meant to copy it can cause a lot of
trouble, so be careful!
Dragging a fle or folder in One Commander
will always move it. To copy, you must always
hold the Ctrl key down.
One Commander attaches a label to the fle
or folder being dragged to tell you whether
it's being moved (red label) or copied (greenlabel).

right-clicking on a folder or fle.
Create new folders: click on the
button (orCtrl+Shift+N) in the Folder Pane Toolbar:

Create a new fle from a template: click on the
button (or Ctrl+N); you can select from a number of
popular fle types to create a new fle of that type in thecurrent folder. You can create as many of your own
templates as you like; see here for more.
Filtering list of folders or fles: with the cursor in afolder column or folder pane, start typing the name of
the folder or fle; folders or fles not containing thestring of characters you've typed are fltered out, so it
also is a quick way of searching for a folder or fle in along list. At the top of the column or pane One
Commander records what you've typed; cancel theflter by clicking the "X" or pressing the Esc key:

You can have as many flters running concurrently as you
like.
Note that the Spacebar key can't be used for fltering,
because it's used for previewing the selected item:

4. Folder columns

use left/right arrowss to move between folder columns.
The right arrow also opens the folder from the Current
Folder pane.
The easiest way of understanding how this works is to try it.
Files or folders selected using the keyboard are surrounded
by a box of "marching ants":

In the Columns Layout, the rightmost column is also theCurrent Folder Pane. Folders in this pane need to be doubleclicked to open (although you can set it to open with a singleclick in Settings > Other).
The columns to the left of the Current Folder Column
compress to allow you a good view of the Current Folder
Column. If they're compressed too much to give a clear viewof their contents, you can expand them by moving themouse cursor over them. You can change many features of
how this works in Settings > Columns, for example how
quickly the columns respond to the mouse movements, howmuch they expand, and so on. Alternatively, if you don't likethese animations, you can turn them of in Settings >Columns.

Browser Tabs
Either Browser can have any number of Tabs, each with its
own Current Folder. So any instance of One Commander canhave a very large number of folders available to be selected
as Current Folders.
You can quickly change focus between Browsers with Alt+F,
and change the order of the Tabs by dragging them.

Tab Aliases
The Tab Alias is the name that appears on the Tab. By default
it is the name of the Tab's Current Folder, but you canchange this by selecting Change alias in the Tab's Context
Menu. You can change this default behavior in Settings >Other, to show the full path for the Tab.

Creating Tabs
Click thebutton to the right of the current set of
Tabs. The new Tab will be a clone of the Tab thatcurrently has the focus, unless you change thisbehaviour in Settings > Other. Alternatively, select the
Tab to be duplicated and press Ctrl+T.
Right-click any folder and select Open in... You have thechoice of opening that folder as a new Tab in the
Current Browser, the other Browser, or a new Window.

Moving/copying Tabs between
Browsers
Tabs can be moved to the other Browser (if open) using
Alt+MMB. Copying a Tab to the other Browser is a two-stepprocess: duplicate the Tab with Ctrl+T or clicking on the
button, then move the new Tab to the other Browsers with
Alt+MMB.

Closing Tabs
Click on the
button at the right-hand side of the Tab(which may not be visible if there are too many Tabs;
see next section), or
MMB

Large numbers of tabs
When you have a large number of Tabs, they shrink to be
narrow enough to accommodate all of them. This will
typically make them too narrow for the label text to bereadable, but their path will be displayed in a Tooltip:

When the cursor passes over narrow tabs, the Close Button
doesn't appear until you click on one of them. When you
do, the tab expands a little so that you can see both the tablabel and the

Button.

Commander's appearance
There is a lot you can do to One Commander's appearance
using its various Settings in particular by choosing adiferent Theme. But there's even more you can do if you
don't mind exploring further under One Commander'shood. You can lift the hood by going to the Themes folder,
C:\User\<User Name>\One Commander\Themes (for theMicrosoft Store version), or the folder in which the Portableversion is installed. You can reach this folder quickly byclicking

on the About Program and then the Settings
Location button at the bottom of the dialog. You can create
a new theme by adding a new folder here and creating theTheme material that you want.

ThemesOne Commander comes with a number of built-in Themes,
which can be found at Settings > Theme. There are the usual
light and dark themes, as well as some alternatives.
A Theme is a combination of File Icons, Folder Icons, aThumbnail (for the Settings > Theme dropdown) and an.xaml fle that controls One Commander's appearance. You
can get a sense of what can be customized by exploring the.xaml fles for the built-in Themes.
You can vary the icons in use by choosing various options
available in Settings > Theme.
Any Theme can be given an Acrylic (translucent) efect bychecking the appropriate box in Settings > Theme. You may

notice a performance hit if you check this box, though.
Health and Safety Warnings:
Always make a copy of a theme before you edit it,
and work with the copy, not the original. When One
Commander is updated, it will overwrite any changes inthe built-in themes.
It's probably safest not to edit the built-in Themefles unless you really know what you are doing, but
to do your experimenting on a Theme that you create
yourself. If you do get into a mess, help is available
here.

Creating new Theme
Easy: make a copy of one of the Themes folders, and workwith that.

Accent Color
You can change the color that fles take when the mousepasses over them or they are selected in Settings > Theme.
Depending on the theme, an Accent color will be usedon certain elements, such as Columns Pane border or
Tabs border.
In some themes, the Accent Color is part of the theme
itself and changing it is disabled (for example in Nordor Nortorn themes).

Copying/moving by Drag and Drop
The approach to dragging and dropping items used byWindows is a bit confusing: it behaves diferently dependingon whether you are dragging and dropping within or
between drives. One Commander's default method isslightly diferent but has the virtue of consistency:
Dragging without Ctrl key: One Commander always
moves the item, regardless of whether the move is
between drives or between folders within the same
drive.
Dragging with Ctrl key: One Commander always copies

You can change the information shown in the Folder Panecolumns, by modifying an existing File View or creating a
new one, using the File View Designer. It is reached from thebutton in the Folder Pane Toolbar and selecting Edit FileViews.
File Views designs are stored in .json fles in the folder<Settings location>\Resources\FileDesigns. The File View
currently being edited is shown in the "Edited view" feld at

Most of the File View Designer is self-explanatory, and theeasiest way of learning how to use it is to create a custom
fle view using the "Save as" button at the bottom of thewindow and experiment with it. You can see the efects ofchanges you make by clicking

near the top of thewindow and viewing the changes in the Edited view pane.
Specifc points:

String Format Column
This is for advanced use only. If it is left blank, all values in
the column are taken from One Commander's Settings. It
allows the user to go into great depth with customizing
formats. Examples that can be used include diferent date
and time formats (see https://docs.microsoft.com/enus/dotnet/standard/base-types/standard-date-and-timeformat-strings), for example the time in a specifc UTC zoneor showing milliseconds, months written in words in theuser's language, numbers formatted with commas, and soon.

Removal Order
When you make a Browser narrower, this setting determines
the order in which columns disappear from the display. You
can think of it as the reluctance of a particular column todisappear, where the higher the number the more reluctant
the column is to vanish. So in the example above, if you
shrink a Browser horizontally, Time is the frst column todisappear and Name is the last. You can verify the Removal
Order settings by clicking

and then moving theresizing handle in the Edited view pane to left and right.

Buttons across the bottom of the window
Load: Loads a File View Design fle (they all end in ".json")from the folder <Settings location>\Resources\FileDesigns.
Save: Saves current File View Design fle (i.e. the File View
Design shown in the Edited view line at the top of the File
View Designer window).
Save as: Saves current File View Design fle under a newname.
Apply to current folder-pane and close (without saving):
Applies the new File View to the current folder pane
temporarily; the next time this folder is viewed, the File View
will revert to the saved version.

You can change the way that fles and folders are displayedin the Folder Pane by changing the File View. One
Commander has a number of built-in File Views, which you
can modify and add to. One Commander remembers theFile View you have selected for each folder.
The File Views are listed by clicking the

button in the
Folder Pane Toolbar. The button pops up the following list:

Default: the basic fle view, showing for each item thename (with some metadata, such as the number ofpages in a .docx fle), "age" of the item (how long since
it was last modifed), date and time of last modifcation,
attributes, and size.
Name Only: displays just fle/folder names, with noother columns.
Powershell: Similar to Default, but with the columns ina diferent order (attributes, date, size, name).
Thumbnail Grid: Displays thumbnails in a grid; change
the size of the thumbnails by holding Ctrl and rotating
the Mouse Wheel.

Folder Columns andNavigation PaneThe folder tree is displayed as a series of columns. A single
click on any folder in a column opens that folder in a newcolumn to its right. Columns that behave like this are known
as Miller columns, in which all of the columns that are partof the tree branches leading to the currently-open folder
remain visible. This makes it easier to see where thecurrently-open folder sits in the folder tree structure, and tonavigate to other branches in the tree.
One Commander adds two features to standard Miller
columns to make it easier to work with folder displays inwhich a lot of folder columns are visible (when you're
working with a folder that is a long way from the drive root):
As each new folder is opened, the columns to its leftshrink to give room for the contents of the current
folder to be easily read.
As the cursor moves over folders to the left of thecurrent folder (i.e. over its parent folders), the folders
under the cursor expand while the cursor is over themso their contents can be seen. The responsiveness andspeed of this expansion, as well as many other featuresof the column display, can be adjusted in Settings >Columns.
Not everyone likes columns to change width in this way. They
can be turned of in Settings > Columns.

Memory management in
One Commander
One Commander is made in Microsoft's .NET framework,
which manages memory for One Commander. Windows
may let a program's memory footprint grow while theprogram is used but when Windows needs memory again, it
will compact the program memory and reclaim unused
resources.
One Commander caches icons so they are loaded faster the
next time they are needed in the program session. All
displayed fle properties are also cached while they are in
the list, so scrolling through large folders will use morememory, but the memory will be released once the user
opens another folder (at Windows' own schedule).
Each thumbnail in the fle list and displayed preview will takea chunk of memory. For example, a previewed 10-Megapixel
photo will take 10x3 Megabytes (3 as number of color
channels), even if the image is a compressed jpeg.
Tabs don’t take additional memory in One Commander.
If you choose to keep the program running in the
background on close (see the option in Settings > Window)
all windows, fle properties, previews and the rest will be
unloaded from memory, but the program will keep cachedicons and compiled code for a faster next start, while
minimizing RAM usage.

The Microsoft Store version of One Commander is notable to show previews of Microsoft Word or Excel fles;
it will, however, show an image preview if there is one
embedded in the fle. This limitation is imposed byWindows, which does not allow the necessary ActiveX
components to run in Store apps.

Resizing individual panes
Most panes are surrounded by a border or divider that canbe dragged to resize the pane in question. Some borders
appear when the cursor moves over them, but are hidden
otherwise.
Many borders or dividers have Drag Handles (the double
dotted lines) and Open/Close Arrows:

Some panes have buttons to open and close them, forexample the Navigation Panes can be opened and closed
using the upwards/downwards pointing arrows to the rightof the Folder Column headers:or thebutton that appears at the top of the Main Toolbar

Most of One Commander's settings take the form ofcheckboxes or sliders, and are self-explanatory. In thissection we provide some additional explanations where they
are needed.
Sliders can be adjusted either with the mouse cursor, or byclicking on them and moving them with cursor keys. Cursor
keys can be helpful if the slider is a little laggy (whichhappens when One Commander is showing you the resultsof the change in real time, as for example in Settings >General > Item properties).
The settings are stored in folders at C:\Users\<username>\OneCommander\ for the Microsoft Store version, orin {OneCommanderFolder}\Settings for portable version.
They can be reached quickly by clicking on(Aboutprogram) in the Main Window and then clicking the Settings
Location button at the bottom of the dialog.
Some settings changes are applied immediately; others
require a program restart. You'll know you need to do thiswhen this appears at the bottom of the settings window:. If you make a change that
requires a restart, One Commander will ask whether you
want to restart the program now:

2. The Main Window
The Main Window displays a sidebar and either one or two
browsers. When One Commander is opened for the frst
time, both browsers are visible with the theme and layout
you chose from the opening dialog box. The Folder Columns
are hidden to start with in the Standard Layout. You canreveal them by clicking the
button, to the right of thefolder path at the top of each browser:

or by dragging down the Navigation/Folder Pane Divider justunderneath the folder path (keep dragging until themessage "Expand more to show pane" disappears):

The browsers can be displayed in either Standard orColumns layouts. You can switch back and forth between
them as often as you like using the Layout Button (or)
at the bottom left of the Main window (in the Main Toolbar;
see next section on this page). When you do this, the only
thing that changes is the layout; the fles, folders, andsettings remain the same.

each case, <path> must be the full pathname for the path
you want One Commander to open in, enclosed in quotes if
the path contains spaces, e.g. "C:\Users\<Username>\Documents".
At a particular path:onecommander.exe "C:\path"

To open in a new tab:
onecommander.exe -o "C:\path" -newtab
To start One Commander with the Main Window inthe default position (the equivalent of starting One
Commander and pressing Shift+F1):

Window, but One Commander continues to run in the
background so that it can be quickly re-opened without
having to be reloaded. When the Main Window is closed inthis way, any processes such as fle operations that were in
progress when the WindowClose button was clicked will becompleted properly. Also, when it is running in the
background, One Commander monitors for drive changes sothat you're able to see fle changes when you open the Path
Editor.
After showing the "Run in background?" dialog box, One
Commander then explains how to close it down completely:https://onecommander.com/help/3._Full_reference_guide/Settings/..\Starting,_Reopening,_and_Closing_One_Commander.html[2022-05-19 22:17:25]

5. Troubleshooting
If something isn't working as it should, before you try
anything else, check to see whether there is an update
available for One Commander.

Shortcut key isn't working
This could be because it's being intercepted by another app,which can be tricky to track down. Windows allows apps tolist the system-wide hotkeys currently in use, but refuses to
identify which applications are using them. A utility called
Ethervane ActiveHotkeys (portable), which may not be
supported any more, lists hotkeys currently in use by
Windows. Then, by closing down apps one by one you
should be able to identify the culprit.

Filename not accepted
The following characters are not permitted in Windows fle
names:<>:"/\|?*
More information on fle naming can be found here.

Some folders, e.g. C:\Users\<user name>\AppData,
not visible
Make sure that you've checked all the "Visibility" options in
Settings > View.

5. Troubleshooting

OK, we get the irony: if you can't start the app, how can you
read this? Except that there is a copy of this manual at
OneCommander.com, which is presumably where you'rereading this now. Here are three approaches, starting withthe simplest and ending with a restart that involves losing
your settings.
Approach 1: The Main Window may be hidden of screen.
Try pressing Shift+F1 to bring it back into view.
If that doesn't work:
Approach 2: One Commander may be "frozen". Open the
Windows Task Manager, click on the Processes tab, andsearch for any entries for One Commander, either in theApps or Background Processes sections. If you fnd any,
select them and click the "End task" button at the bottom
right-hand corner of the Task Manager window, or right-clickon them and select "End task". Try starting One Commander.
If that doesn't work:
Approach 3: There may be a problem with One
Commander's main settings fle.
1. Find the Settings folder (e.g. C:\Users\<username>\OneCommander\Settings\).
2. Rename the fle "OneCommanderV3.json" to somethingelse, for example"OneCommanderV3.json.deactivated". This fle will berecreated when you get to Step 4.
3. Open the Windows Task Manager, click on theProcesses tab, and search for any entries for One
Commander, either in the Apps or Background
Processes sections. If you fnd any, select them andclick the "End task" button at the bottom right-handcorner of the Task Manager window, or right-click onthem and select "End task".
4. Try starting One Commander. If it works, great!
However, you'll need to go through your Settings again,
because they will have been reset to One
Commander's default values.

5. Troubleshooting

Something is spamming your flesystem with flechanges errors
If a program is constantly changing many fles at once thebufer that holds flesystem changes may get full and One
Commander will miss changes on disk. It may also degrade
the life of your SSD (solid state drive). Go to Settings >Advanced for a utility that will help you identify theofending program.

When maximized on a two-screen display, theMain Window spreads slightly on to the second
screenThis is an unfortunate feature of the third party library that
renders the Main Window. The only fx available is to turn of
the Acrylic window efect in Settings > Theme, shut down the
program and restart.

Drag and drop not working with other programs
If you can't get another program to accept a fle dropped
when you've dragged it from One Commander, try selecting"Use old Drag & Drop system" in Settings > Advanced.

If none of that helped...
Please email support@onecommander.com or go to the
support forum at Google Groups.

the ones to the left of the Current Folder Column, using the:Mouse: Click on the folder. A new column displaying thecontents of that folder will appear to the right of the column

Keyboard: You can move through the entire directory treeusing just four cursor keys. You can:move between panes, and between folders and fleswithin panes, using a combination of Tab and Cursor
Arrow keys (Shift+Tab to move in the opposite
direction), and Enter to open folders (this doesn't movethe keyboard focus to the folder within) or fles;

4. Folder columns

use left/right arrowss to move between folder columns.
The right arrow also opens the folder from the Current
Folder pane.
The easiest way of understanding how this works is to try it.
Files or folders selected using the keyboard are surrounded
by a box of "marching ants":

In the Columns Layout, the rightmost column is also theCurrent Folder Pane. Folders in this pane need to be doubleclicked to open (although you can set it to open with a singleclick in Settings > Other).
The columns to the left of the Current Folder Column
compress to allow you a good view of the Current Folder
Column. If they're compressed too much to give a clear viewof their contents, you can expand them by moving themouse cursor over them. You can change many features of
how this works in Settings > Columns, for example how
quickly the columns respond to the mouse movements, howmuch they expand, and so on. Alternatively, if you don't likethese animations, you can turn them of in Settings >Columns.

3. The Browsers and Layouts
The browsers are divided into three main panes (seescreenshots below):
Navigation Pane: Shows all attached and mapped
drives as a series of Miller columns that allow you tonavigate up and down the folder trees for each drive.
Current Folder Pane: Shows the contents of the folderthat is currently selected in the Navigation Pane.
Details Pane: Shows details of the folder or fle that iscurrently selected in the Current Folder Pane. If a fle isselected, this pane shows a preview of the contents ofthe fle if it can (not all fle types are supported).

Layouts
One Commander provides two layouts: Standard andColumns. You can see the diference by clicking on the/

buttons in the Main Toolbar. In brief, the Standard Layout
shows one or both Browsers side-by-side and a set of Folder
Columns at the top of the Browser with the Current Folder
below them, while the Columns Layout sets the Browsers
one above the other, with the Current Folder to the right, as
the fnal column in the Folder Column display. Path selection
is slightly diferent in each display, but other than that it isentirely a matter of personal preference as to which you use.

The Browsers
You can create multiple independent fle/folder views in eachhttps://onecommander.com/help/3._Full_reference_guide/Settings/..\..\2._Quick_introductory_guide\3._The_Browsers_and_Layouts.html[2022-05-19 22:18:07]

3. The Browsers and Layoutsbrowser by adding tabs. Click on the
button to the rightof the Browser Tabs to create a new tab, which will be aclone of the current tab (i.e. the tab that currently has thefocus). Alternatively, you can also specify a particular path
for all new tabs in Settings > Other.
Tabs can be closed by clicking on the

button that appears
when you move the cursor over the tab, or by clicking MMB.
Once deleted, they can't be restored.

You can resize either browser by dragging their borders, or
the Browser Divider separating them. Some borders have adrag handle surrounded by arrows:. The draghandle isn't strictly speaking necessary; it serves as areminder that the divider can be dragged. The arrows jump
the divider to the end of its travel.
If you try to reduce the width of a browser below a certain
point it tells you that it's about to collapse, meaning that it's
about to disappear from view so that you see a singlebrowser view. You can restore the dual-browser view bydragging the border or Browser Divider back again (or use
the drag handle or arrow). The browser will be restored
exactly as it was before.
If the Main Window is too narrow to show both Browsers in
the Standard Layout, one Browser will be closed. It will be reopened if you make the Main Window wide enough.
You can create background images for the Folder Panes —click here for how to do it.

Open folders or fles by double-clicking on them (youcan change this to a single click in Settings > Other) orpressing Enter.
Move/copy fles using
Mouse: Drag and drop between browsers or toand from other Windows apps (to copy, hold Ctrl
key down while dragging). Note that One
Commander drag and drop works a littlediferently from Windows File Explorer. Moving afle when you meant to copy it can cause a lot of
trouble, so be careful!
Dragging a fle or folder in One Commander
will always move it. To copy, you must always
hold the Ctrl key down.
One Commander attaches a label to the fle
or folder being dragged to tell you whether
it's being moved (red label) or copied (greenlabel).

Filtering list of folders or fles: with the cursor in afolder column or folder pane, start typing the name of
the folder or fle; folders or fles not containing thestring of characters you've typed are fltered out, so it
also is a quick way of searching for a folder or fle in along list. At the top of the column or pane One
Commander records what you've typed; cancel theflter by clicking the "X" or pressing the Esc key:

You can have as many flters running concurrently as you

Installing One Commander
V3
One Commander Version 3 comes in two forms, both of which
will be automatically updated as new versions become
available. The Store version is easier to install, but has a few
minor limitations. The Portable version does not have theselimitations, but takes a couple more steps to install.
Portable version: This is downloaded fromhttps:\\onecommander.com, and comes as a zip fle.
Unlike normal Windows programs, it can be installed inany folder of your choice, including on portable drives(e.g. USB drives). To install this version:
Download a zip fle from onecommander.com.
Right-click the zip fle and select "Properties". At thebottom of the General tab, under "Security", checkthe "Unblock" box:

Extract the contents of the zip fle in the usual manner tothe folder in which you want to store the program.
Create a shortcut for the fle OneCommander.exe: Rightclick on the fle OneCommander.exe and select "Create
shortcut". This creates the shortcut fle"OneCommander.exe - Shortcut.lnk", which, when you
double-click on it, runs One Commander.
Move the shortcut to any convenient location. For
example, you can put it on the Start Menu, at C:\Users\<username>\AppData\Roaming\Microsoft\Windows\Start

Microsoft Store version: This is installed by the Store on
your computer and updated from there. It is mainly thesame as the Portable version, with the following
diferences:
The Settings fles are found at "C:\Users\<Username>\OneCommander".
It cannot run ActiveX controls, meaning that One
Commander's native Preview can't open certain fle
types (mainly Microsoft Ofce fles).
Upgrading from Version 2: If you want to re-use your Version
2 settings, go to Settings > Window and click on

Installing One Commander on morethan one computer
If you would like to move your settings to One Commander ona second computer:
1. Install One Commander on the second computer.
2. On a removable medium (e.g. a USB drive), make a copyof the frst computer's fle "OneCommanderV3.json",which you can fnd in the Settings folder.
3. On the second computer, locate the Settings folder andrename the fle "OneCommanderV3.json" to somethingelse, for example "OneCommanderV3.json.installation".
4. Copy/move the "OneCommanderV3.json" fle from yourfrst computer into the Settings folder on the second
computer.
This will move over your basic settings. Others, such as
Favorites and Tabs, can't be copied over because theyreference folders specifc to the frst computer.
If you have a Pro licence, you will need to contact
support@onecommander.com to arrange for the Pro licenceto be valid on the second computer.

which you'll fnd in Settings > Theme, which is also where
you can switch between them. You can edit them if you
don't mind editing .xaml fles.
You can give the themes an acrylic (translucent) efect bychecking the appropriate box in Settings > Theme, as well aschange the icons that One Commander uses as well as the

6. Sidebar
The Sidebar is the centre of operations for One Commander.
It is divided into three main sections:

1. Drives
This lists the currently-attached and mapped drives. It can be
hidden by going to Settings > Window > uncheck Showdrives in Sidebar. The

button gives the following options:

Hide drives from the sidebar: hides the list of drives,
but keeps the box.
Refresh everything (F5; refreshes all folder displays tomake sure they're up to date).
Map network drive (mapped network drives will belabelled both with the destination folder in the mapped
drive and the network path in parentheses).

2. Favorites
One Commander allows you to identify as many favorite
folders as you like. They are arranged into groups in the
Sidebar. One Commander creates an initial group from a listof standard folders in your C:\Users\<username> folder, andyou can add as many groups as you like by clicking the "NewGroup" button. Here's an example of a Favorites Group:https://onecommander.com/help/3._Full_reference_guide/Settings/..\..\2._Quick_introductory_guide\6._Sidebar.html[2022-05-19 22:18:51]

6. Sidebar

Favorite folders have two basic uses:
They act as bookmarks for folders you use often:
click on a favorite folder and it opens in thecurrently-selected browser, in the currentlyselected tab
MMB opens the path in a new tab in the currentlyselected browser
You can quickly move or copy fles or folders from abrowser to a favorite folder by dragging (to move), or
holding the Ctrl key down and dragging (to copy), thefle or folder from the browser and dropping it onto
one of the items in the Favorites Group. Note thatdragging a fle or folder to a favorites group does notcreate a new favorite; it just moves or copies thatfolder or fle to the chosen favorite.
Basic operations for favorites groups:
Add folder to group: Click the "+" button to the right of
the group's name.
Rearrange folders within group, move folders
between groups: Drag folders up and down withingroup or between groups.
Create aliases (alternative names) for folders ingroups: Right-click on folder name and select "Change
Alias".
Remove folders from groups: Right-click on folder
name and select "Remove Path from List".
