This article outlines the additional software packages necessary to expand the features and functionality of file managers, particularly where using a
window manager
such as
Openbox
. The ability to access partitions and removable media without a password—if affected—has also been provided.
Áttekintés
Megjegyzés
When installed, the software packages listed below will automatically be sourced by all installed - and capable - file managers, and within all desktop environments and/or window managers.
A file manager alone will not provide the features and functionality that users of full desktop environments such as
Plasma
or
Xfce
will be accustomed to. This is because additional software packages will be required to enable a given file manager to:
Display and access other partitions
Display, mount, and access removable media (e.g. USB sticks, optical discs, and digital cameras)
Enable networking / shared networks with other installed operating systems
Enable thumbnailing
Archive and extract compressed files
Automatically mount removable media
When a file manager has been installed as part of a full desktop environment, most of these packages will usually have been installed automatically. Consequently, where a file manager has been installed for a standalone window manager then - as is the case with the window manager itself - only a basic foundation will be provided. The user must then determine the nature and extent of the features and functionality to be added.
Additional features
This article or section needs expansion.
Reason:
Mention KDE file managers which use KIO instead of GVFS for mounting and other functionality (Discuss in
Talk:File manager functionality (Magyar)
)
When using a lightweight environment, the more added file manager features, the more memory usage is needed. See also
udisks
.
Felcsatolás
The Gnome virtual filesystem (
gvfs
) provides mounting and trash functionality. GVFS uses
udisks2
for mounting functionality and is the recommended solution for most file managers.
Folders used by GVFS:
/usr/lib/
contains
gvfsd-*
files, where
*
refers to the various supported file system types.
/usr/share/gvfs/mounts/
contains mount rules for GVFS. To use one's own rules, create
~/.gvfs/mounts
.
Additional packages for installation usually follows the
gvfs-* pattern
, for example:
gvfs-mtp
: media players and mobile devices that use
MTP
gvfs-gphoto2
: digital cameras and mobile devices that use
PTP
gvfs-afc
: Apple mobile devices
File manager daemon
Most graphical file managers have the ability to automount devices plugged in while the program is running. You can leverage this for a system-wide solution by running the file manager in
daemon
mode (i.e. as a background process), if supported. For example, when using
PCManFM
in
Openbox
, the following command would be added to the
~/.config/openbox/autostart
file:
pcmanfm -d &
It will also be necessary to configure the file manager itself in respect to volume management (e.g. what it will do and what applications will be launched when certain file types are detected upon mounting).
Tipp
Most desktop environments will start the file manager in daemon mode by default so manual intervention will not be required in these use cases.
Standalone
Another option is to install a separate
mount application
. The advantages of using this are:
Less memory may be required to run as a background/
daemon
process than a file manager
It is not file-manager-specific, allowing them to be freely added, removed, and switched
gvfs
is not needed to be installed for mounting, lessening memory usage. If it is installed, then its daemon
can be masked
, and started only on demand. This is useful for example as a fallback for
mtp
, where some implementations may not work.
Networks
Megjegyzés
It will also be necessary to enable
Bluetooth
and/or networking with
Windows
to enable the relevant file manager functionality in turn.
obexftp
AUR
: Bluetooth device mounting and file transfers (see
Bluetooth
)
gvfs-smb
: Windows File and printer sharing for
Non-KDE
desktops (see
Samba
)
kdenetwork-filesharing
: Windows File and printer sharing for
KDE
(see
Samba#KDE
)
sshfs
: FUSE client based on the
SSH
File Transfer Protocol
Windows access
If using
gvfs-smb
, to access Windows/
Cifs
/Samba file shares first open the file manager, and enter the following into the path name, changing
server_name
and
share_name
as appropriate:
smb://
server_name
/
share_name
Apple access
AFP support is included in
gvfs
. To access AFP files first open the file manager, and enter the following into the path name, changing
server_name
and
share_name
as appropriate:
afp://
server_name
/
share_name
sftp access
SFTP support is also included in
gvfs
. To access folders via sftp, open the file manager, and enter the following into the path name, changing
user@server_name
and
folder_name
as appropriate:
sftp://
user@server_name
/
folder_name
WebDAV
For WebDAV, install
gvfs-dnssd
.
davs://
user@server_name
/
folder_name
Thumbnail previews
Megjegyzés
Some file managers may not support thumbnailing, even when the packages listed have been installed. Check the documentation for the relevant file manager.
You may not see thumbnails for remote storage, including
MTP
. Check your file manager's settings, e.g. for
Thunar
one has to set "Show thumbnails: always".
The following packages enable thumbnailing in most file managers, such as
PCManFM
,
SpaceFM
,
Thunar
, and
xfe
AUR
. They are not needed for
KDE
's Dolphin or Konqueror, which use a
separate thumbnailing system
.
tumbler
is the core backend for thumbnailing in many file managers. This
must
be installed to enable thumbnailing for various file types. It is not required for
GNOME Files
.

Use PCManFM to get thumbnails for other file types
This article or section needs language, wiki syntax or style improvements. See
Help:Style
for reference.
Reason:
This section is not specific to PCManFM, it should be rewritten/generalized. (Discuss in
Talk:File manager functionality (Magyar)
)
PCManFM
supports image thumbnails out of the box. However, in order to view thumbnails of other file types, PCManFM uses the information provided in the files located at
/usr/share/thumbnailers
. The packages which provide a thumbnailer usually add the corresponding
.thumbnail
file at
/usr/share/thumbnailers
. For example, in order to get thumbnails for OpenDocument files, you may install
libgsf
from the official repositories. For video files' thumbnails, the package
ffmpegthumbnailer
is required. For PDF files, you may install
evince
from the official repositories, which provides
evince-thumbnailer
and the corresponding file at
/usr/share/thumbnailers
. However, if you prefer not to install
evince
, you can also replicate the functionality of
evince-thumbnailer
using
imagemagick
's
convert
command. This is accomplished by creating a new file with the
.thumbnailer
extension (e.g.:
imagemagick-pdf.thumbnailer
) at
/usr/share/thumbnailers
with the following content:
[Thumbnailer Entry]
TryExec=convert
Exec=convert %i[0] -background "#FFFFFF" -flatten -thumbnail %s %o
MimeType=application/pdf;application/x-pdf;image/pdf;
Megjegyzés
The
[0]
next to the input file is specified so that
convert
only generates a thumbnail of the first page. This is a
convert
-specific syntax and has nothing to do with the syntax of the thumbnailers' files.
Following this example, you can specify custom thumbnailers by creating your own
.thumbnail
files. Keep in mind that
%i
refers to the input file (the file which will have its thumbnail made),
%o
to the output file (the thumbnail image) and
%s
to the size of the thumbnail. These parameters will be automatically substituted with the corresponding data and passed to the thumbnailer program by PCManFM.
Tipp
If you only get thumbnails of certain files and not of all the files of the same type try increasing the maximum file size of the files that get a thumbnail at
Edit > Preferences > Display
.
Archive files
To extract compressed files such as tarballs (
.tar
and
.tar.gz
) within a file manager, it will first be necessary to install a GUI archiver such as
file-roller
. See
List of applications/Utilities#Archiving and compression tools
for further information. An additional package such as
unzip
must also be installed to support the use of zipped
.zip
files. Once an archiver has been installed, files in the file manager may consequently be right-clicked to be archived or extracted.
Archive files are mounted under folder
/run/user/$(id -u)/gvfs/
with automatically created mount point that contains full path to the file in its name where all
/
are replaced with
%252F
and
:
replaced with
%253A
hex codes
.
Example of path to the mounted archive
/full/path/to/file/name.zip
/run/user/$(id -u)/gvfs/archive:host=file%253A%252F%252F%252F
full%252Fpath%252Fto%252Ffile%252Fname.zip
NTFS read/write support
See the
NTFS
article.
Desktop notifications
Some file managers make use of
desktop notifications
to confirm various events and statuses like mounting, unmounting and ejection of removable media.
Enable Trash functionality on different filesystems (external drives)
The factual accuracy of this article or section is disputed.
Reason:
Should these folders not be created automatically? When is it necessary to create them manually? (Discuss in
Talk:File manager functionality (Magyar)
)
Make
trash directories
.Trash-
<uid>
for each users on the top level of filesystems:
For example (mount point: /media/sdc1, uid: 1000, gid: 1000):
# mkdir /media/sdc1/.Trash-1000
and
chown
them:
# chown 1000:1000 /media/sdc1/.Trash-1000
Hibaelhárítás
"Not Authorized" when attempting to mount drives
File managers using
udisks
require a
polkit
authentication agent. See
polkit#Authentication agents
.
Password required to access partitions
The need to enter a password to access other partitions or mounted removable media will likely be due to the default permission settings of
udisks2
. More specifically, permission may be set to the root account only, not the user account. See
Udisks#Configuration
for details.
Directories are not opened in the file manager
You may find that an application that is not a file manager,
Audacious
or
Visual Studio Code
for example, is set as the default application for opening directories — an application that specifies that it can handle the
inode/directory
MIME type in its desktop entry can become the default. You can query the default application for opening directories with the following command:
$ xdg-mime query default inode/directory
To ensure that directories are opened in the file manager, run the following command:
$ xdg-mime default
my_file_manager
.desktop inode/directory
where
my_file_manager
.desktop
is the desktop entry for your file manager —
org.gnome.Nautilus.desktop
for example.
Tipp
If you want the change to be system-wide, run the command above as root or create/edit the following file:
/usr/share/applications/mimeapps.list
[Default Applications]
inode/directory=
my_file_manager
.desktop
D-Bus
Some other applications instead use the
org.freedesktop.FileManager1
D-Bus protocol (e.g.
Firefox
). The following shows a list of currently installed services supporting this protocol:
$ grep -R FileManager1 /usr/share/dbus-1/services
To change what file manager is opened, symlink the file to
$XDG_DATA_HOME/dbus-1/services/
or
$HOME/.local/share/dbus-1/services/
if XDG_DATA_HOME variable is empty. Additionally, before the changes become active, kill the program currently implementing the D-Bus service.
Mount points created manually in /etc/fstab are not displayed
Due to this
gvfs commit
you need to create your mount point inside
/media/your-user-name/
.
