4.1.3 Video player
You can play videos in Nextcloud with the Video Player app by simply clicking on the file. Video streaming by the native
Nextcloud video player depends on your Web browser and the video format. If your Nextcloud administrator has enabled
video streaming, and it doesn’t work in your Web browser, it may be a browser issue. See https://developer.mozilla.org/
en-US/docs/Web/HTML/Supported_media_formats#Browser_compatibility for supported multimedia formats in Web
browsers.

hide these files in your file browsers, unless you choose to display them. Usually these are configuration files, so having
the option to hide them reduces clutter.

4.1.5 Previewing files
You can display uncompressed text files, OpenDocument files, videos, and image files in the Nextcloud embedded viewers
by clicking on the file name. There may be other file types you can preview if your Nextcloud administrator has enabled
them. If Nextcloud cannot display a file, it starts a download process and downloads the file to your computer.

4.1.12 Creating or connecting to a Federation Share link
Federated Cloud Sharing allows you to mount file shares from remote Nextcloud servers, and manage them just like a
local share. See Using Federation Shares to learn to how to create and connect to new Federated Cloud shares.

4.2 Accessing Nextcloud files using WebDAV
Nextcloud fully supports the WebDAV protocol, and you can connect and synchronize with Nextcloud Files over WebDAV. In this chapter, you will learn how to connect Linux, macOS, Windows, and mobile devices to your Nextcloudserver.
WebDAV stands for Distributed Authoring and Versioning. It is an HTTP extension that makes it easy to create, read,and edit files hosted on remote Web servers. With a WebDAV, client you can access your Nextcloud Files (including
shares) on Linux, macOS and Windows in a similar way as any remote network share, and stay synchronized.
Before we get into configuring WebDAV, let’s take a quick look at the recommended way of connecting client devices to
Nextcloud.

4.2. Accessing Nextcloud files using WebDAV

17

Nextcloud User Manual, Release latest

4.2.1 Official Nextcloud desktop and mobile clients
The recommended way to synchronize a computer with a Nextcloud server is by using the official Nextcloud sync clients.
You can configure the client to save files in any local directory and you can choose which directories on the Nextcloudserver to sync with. The client displays the current connection status and logs all activity, so you always know whichremote files have been downloaded to your PC and you can verify that files created and updated on your local PC areproperly synchronized with the server.
The recommended way to synchronize Android and Apple iOS devices is by using the official Nextcloud mobile apps.
To connect the official Nextcloud apps to a Nextcloud server use the same URL you use to access Nextcloud from yourweb browser - e.g.:https://cloud.example.com
https://example.com/nextcloud (if Nextcloud is installed in a subdirectory called,→"nextcloud")

4.2.2 Third-party WebDAV clients
If you prefer, you may also connect your computer to your Nextcloud server by using any third-party client that supports
the WebDAV protocol (including what may be built into your operating system).
You can also use third-party WebDAV capable apps to connect your mobile device to Nextcloud.
When using third-party clients, keep in mind that they may not be optimized for use with Nextcloud or implement
capabilities you consider important to your use case.
Mobile clients that Nextcloud community members have reported using include:• FolderSync (Android)• WebDAV Navigator (iPhone)
The URL to use when configuring third-party apps to connect to Nextcloud is a bit lengthier than the one for official
clients:
https://cloud.example.com/remote.php/dav/files/USERNAME/
https://example.com/nextcloud/remote.php/dav/files/USERNAME/ (if Nextcloud is␣,→installed in a subdirectory called "nextcloud")Note: When using a third-party WebDAV client (including your operating system’s built-in client), you should use an application password for login rather than your regular password. In addition improved security, this increases performance
significantly <https://github.com/nextcloud/server/issues/32729#issuecomment-1556667151>_. To configure an application password, log into the Nextcloud Web interface, click on the avatar in the top right and choose Personal settings.
Then choose Security in the left sidebar and scroll to the very bottom. There you can create an app password (which canalso be revoked in the future without changing your main user password).

Note: In the following examples, you should replace example.com/nextcloud with the URL of your Nextcloud server(omit the directory part if the installation is in the root of your domain), and USERNAME with the username of theconnecting user.
See the WebDAV URL (bottom left in settings) on your Nextcloud.

4.2.3 Accessing files using LinuxYou can access files in Linux operating systems using the following methods.
Nautilus file manager
When you configure your Nextcloud account in the GNOME Control Center, your files will automatically be
mounted by Nautilus as a WebDAV share, unless you deselect file access.
You can also mount your Nextcloud files manually. Use the davs:// protocol to connect the Nautilus file manager toyour Nextcloud share:
davs://example.com/nextcloud/remote.php/dav/files/USERNAME/

Note: If your server connection is not HTTPS-secured, use dav:// instead of davs://:Note: The same method works for other file managers that use GVFS, such as MATE’s Caja and Cinnamon’s Nemo.

4.2. Accessing Nextcloud files using WebDAV

19

Nextcloud User Manual, Release latest

Accessing files with KDE and Dolphin file manager
To access your Nextcloud files using the Dolphin file manager in KDE, use the webdav:// protocol:
webdav://example.com/nextcloud/remote.php/dav/files/USERNAME/

You can create a permanent link to your Nextcloud server:
1. Open Dolphin and click “Network” in the left-hand “Places” column.
2. Click on the icon labeled Add a Network Folder. The resulting dialog should appear with WebDAV alreadyselected.
3. If WebDAV is not selected, select it.
4. Click Next.
5. Enter the following settings:• Name: the name you want to see in the Places bookmark, for example, Nextcloud.
• User: the Nextcloud username you used to log in, for example, admin.
• Server: the Nextcloud domain name, for example, example.com (without http:// before or directories afterwards).
• Folder – Enter the path nextcloud/remote.php/dav/files/USERNAME/.
6. (Optional) Check the “Create icon” checkbox for a bookmark to appear in the Places column.
7. (Optional) Provide any special settings or an SSL certificate in the “Port & Encrypted” checkbox.

4.2.4 Creating WebDAV mounts on the Linux command line
You can create WebDAV mounts from the Linux command line. This is useful if you prefer to access Nextcloud thesame way as any other remote filesystem mount. The following example shows how to create a personal mount and haveit mounted automatically every time you log in to your Linux computer.
1. Install the davfs2 WebDAV filesystem driver, which allows you to mount WebDAV shares just like any otherremote filesystem. Use this command to install it on Debian/Ubuntu:
apt-get install davfs2

2. Use this command to install it on CentOS, Fedora, and openSUSE:
yum install davfs2

3. Add yourself to the davfs2 group:

20

Chapter 4. Files & synchronization

Nextcloud User Manual, Release latest

usermod -aG davfs2 <username>

4. Then create a nextcloud directory in your home directory for the mount point, and .davfs2/ for your personal
configuration file:mkdir ~/nextcloud
mkdir ~/.davfs2

5. Copy /etc/davfs2/secrets to ~/.davfs2:
cp/etc/davfs2/secrets ~/.davfs2/secrets

6. Set yourself as the owner and make the permissions read-write owner only:
chown <linux_username>:<linux_username> ~/.davfs2/secrets
chmod 600 ~/.davfs2/secrets

7. Add your Nextcloud login credentials to the end of the secrets file, using your Nextcloud server URL and your
Nextcloud username and password:
https://example.com/nextcloud/remote.php/dav/files/USERNAME/ <username> <password>or$PathToMountPoint $USERNAME $PASSWORD
for example/home/user/nextcloud john 1234

8. Add the mount information to /etc/fstab:
https://example.com/nextcloud/remote.php/dav/files/USERNAME/ /home/<linux_,→username>/nextcloud davfs user,rw,auto 0 0

9. Then test that it mounts and authenticates by running the following command. If you set it up correctly you won’t
need root permissions:
mount ~/nextcloud

10. You should also be able to unmount it:umount ~/nextcloudNow every time you login to your Linux system your Nextcloud share should automatically mount via WebDAV in your~/nextcloud directory. If you prefer to mount it manually, change auto to noauto in /etc/fstab.

4.2.5 Known issues

Nextcloud User Manual, Release latest

Solution
If you experience trouble when you create a file in the directory, edit /etc/davfs2/davfs2.conf and add:
use_locks 0Problem
Certificate warnings
Solution
If you use a self-signed certificate, you will get a warning. To change this, you need to configure davfs2 to recognize
your certificate. Copy mycertificate.pem to /etc/davfs2/certs/. Then edit /etc/davfs2/davfs2.
conf and uncomment the line servercert. Now add the path of your certificate as in this example:
servercert /etc/davfs2/certs/mycertificate.pem

4.2.6 Accessing files using macOS
Note: The macOS Finder suffers from a series of implementation problems and should only be used if the Nextcloudserver runs on Apache and mod_php, or Nginx 1.3.8+. Alternative macOS-compatible clients capable of accessing
WebDAV shares include open source apps like Cyberduck (see instructions here) and Filezilla. Commercial clients
include Mountain Duck, Forklift, Transmit, and Commander One.
To access files through the macOS Finder:
1. From the Finder’s top menu bar, choose Go > Connect to Server…:

22

Chapter 4. Files & synchronization

Nextcloud User Manual, Release latest

2. When the Connect to Server… window opens, enter your Nextcloud server’s WebDAV address in the Server
Address: field, i.e.:
https://cloud.YOURDOMAIN.com/remote.php/dav/files/USERNAME/

3. Click Connect. Your WebDAV server should appear on the Desktop as a shared disk drive.

4.2.7 Accessing files using Microsoft Windows
If you use the native Windows implementation of WebDAV, you can map Nextcloud to a new drive using Windows
Explorer. Mapping to a drive enables you to browse files stored on a Nextcloud server the way you would browse files
stored in a mapped network drive.
Using this feature requires network connectivity. If you want to store your files offline, use the Desktop Client to sync all
files on your Nextcloud to one or more directories of your local hard drive.
Note: Windows 10 now defaults to allow Basic Authentication if HTTPS is enabled before mapping your drive.
On older versions of Windows, you must permit the use of Basic Authentication in the Windows Registry:• launch regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\WebClient\Parameters.
• Create or edit the BasicAuthLevel (Windows Vista, 7 and 8), or UseBasicAuth (Windows XP and Windows Server 2003), DWORD value and set its value data to 1 for SSL connections. A value of 0 means that BasicAuthentication is disabled, and a value of 2 allows both SSL and non-SSL connections (not recommended).
• Then exit Registry Editor, and restart the computer.

Mapping drives with the command line
The following example shows how to map a drive using the command line. To map the drive:
1. Open a command prompt in Windows.
2. Enter the following line in the command prompt to map to the computer Z drive:
net use Z: https://<drive_path>/remote.php/dav/files/USERNAME/ /user:youruser␣
,→yourpassword

with <drive_path> as the URL to your Nextcloud server. For example:

The computer maps the files of your Nextcloud account to the drive letter Z.
Note: If you get the following error System error 67 has occurred. The network name cannot
be found., open the Services app and make sure that the WebClient service is running and started automaticallyat startup.

Note: Though not recommended, you can also mount the Nextcloud server using HTTP, leaving the connection unencrypted.
If you plan to use HTTP connections on devices while in a public place, we strongly recommend using a
VPN tunnel to provide the necessary security.
An alternative command syntax is:
net use Z: \\example.com@ssl\nextcloud\remote.php\dav /user:youruser
yourpassword

Mapping drives with Windows Explorer
To map a drive using Microsoft Windows Explorer:
1. Open Windows Explorer on your MS Windows computer.
2. Right-click on Computer entry and select Map network drive… from the drop-down menu.
3. Choose a local network drive to which you want to map Nextcloud.
4. Specify the address to your Nextcloud instance, followed by /remote.php/dav/files/USERNAME/.
For example:
https://example.com/nextcloud/remote.php/dav/files/USERNAME/

Note: For SSL-protected servers, check Reconnect at sign-in to ensure that the mapping is persistent upon
subsequent reboots. If you want to connect to the Nextcloud server as a different user, check Connect using
different credentials.
5. Click the Finish button.
Windows Explorer maps the network drive, making your Nextcloud instance available.

4.2.8 Accessing files using Cyberduck
Cyberduck is an open source FTP, SFTP, WebDAV, OpenStack Swift, and Amazon S3 browser designed for file transfers
on macOS and Windows.
Note: This example uses Cyberduck version 4.2.1.
To use Cyberduck:
1. Specify a server without any leading protocol information.
For example: example.com
2. Specify the appropriate port.
The port you choose depends on whether or not your Nextcloud server supports SSL. Cyberduck requires that you
select a different connection type if you plan to use SSL.
For example:• 80 for unencrypted WebDAV• 443 for secure WebDAV (HTTPS/SSL)
3. Use the ‘More Options’ drop-down menu to add the rest of your WebDAV URL into the ‘Path’ field.
For example: remote.php/dav/files/USERNAME/
Now Cyberduck enables file access to the Nextcloud server.

4.2.9 Accessing public shares over WebDAV
Nextcloud provides the possibility to access public shares anonymously over WebDAV.
To access the public share, open:
https://example.com/nextcloud/public.php/webdav

in a WebDAV client, use the share token as username and the (optional) share password as the password. For example,
with a share link https://example.com/s/kFy9Lek5sm928xP, kFy9Lek5sm928xP will be the username.
Note: Settings → Administration → Sharing → Allow users on this server to send shares to other servers. This
option also allows WebDAV access to public shares and needs to be enabled to make this feature work, except if cURLis being used (see below).

Solution 1
The Windows WebDAV Client might not support Server Name Indication (SNI) on encrypted connections. If you encounter an error mounting an SSL-encrypted Nextcloud instance, contact your provider about assigning a dedicated IP
address for your SSL-based server.
Solution 2
The Windows WebDAV Client might not support TLSv1.1 and TLSv1.2 connections. If you have restricted your server
config to only provide TLSv1.1 and above the connection to your server might fail. Please refer to the WinHTTP documentation for further information.

Problem
Adding a WebDAV drive on Windows via the above described steps does not display the correct size of in Nextcloudavailable space and instead shows the size of the C: drive with its available space.
AnswerUnfortunately is this a limitation of WebDAV itself, because it does not provide a way for the client to get the available
free space from the server. Windows automatically falls back to show the size of the C: drive with its available spaceinstead. So unfortunately there is no real solution to this problem.

4.3 Managing deleted files
When you delete a file in Nextcloud, it is not immediately deleted permanently, only moved into the trash bin. It is not
permanently deleted until you manually delete it, or when the Deleted Files app deletes it to make room for new files.
Find your deleted files by clicking on the Deleted files button on the Files page of the Nextcloud Web interface. You’ll
have options to either restore or permanently delete files.

4.3.1 Quotas
Deleted files are not counted against your storage quota. Only your personal files count against your quota, not files whichwere shared with you. (See Storage quota to learn more about quotas.)

4.3.2 What happens when shared files are deleted
Deleting files gets a little complicated when they are shared files, as this scenario illustrates:
1. User1 shares a folder “test” with User2 and User3
2. User2 (the recipient) deletes a file/folder “sub” inside of “test”
3. The folder “sub” will be moved to the trash bin of both User1 (owner) and User2 (recipient)
4. But User3 will not have a copy of “sub” in their trash bin
When User1 deletes “sub” then it is moved to User1’s trash bin. It is deleted from User2 and User3, but not placed intheir trash bins.
When you share files, other users may copy, rename, move, and share them with other people, just as they can for any
computer files; Nextcloud does not have magic powers to prevent this.

4.3.3 How the deleted files app manages storage space
To ensure that users do not run over their storage quotas, the Deleted Files app allocates a maximum of 50% of theircurrently available free space to deleted files. If your deleted files exceed this limit, Nextcloud deletes the oldest files (files
with the oldest timestamps from when they were deleted) until it meets the memory usage limit again.
Nextcloud checks the age of deleted files every time new files are added to the deleted files. By default, deleted files stayin the trash bin for 30 days. The Nextcloud server administrator can adjust this value in the config.php file by setting
the trashbin_retention_obligation value. Files older than the trashbin_retention_obligation
value will be deleted permanently. Additionally, Nextcloud calculates the maximum available space every time a new fileis added. If the deleted files exceed the new maximum allowed space Nextcloud will permanently delete those trashedfiles with the soonest expiration until the space limit is met again.
Note: Your administrator may have configured the trash bin retention period to override the storage space management.
See admin documentation for more details.

4.4 Desktop and mobile synchronization
For synchronizing files with your desktop computer, we recommend using the Nextcloud Sync Client for Windows, macOSand Linux.
The Nextcloud Desktop Sync Client enables you to connect to your Nextcloud Server. You can create folders in yourhome directory, and keep the contents of those folders synced with your Nextcloud server. Simply copy a file into thedirectory and the Nextcloud desktop client does the rest. Make a change to the files on one computer, it will flow acrossthe others using these desktop sync clients. You will always have your latest files with you wherever you are.
Its usage is documented separately in the Nextcloud Desktop Client Manual.

4.4.1 Mobile clients
Visit your Personal page in your Nextcloud Web interface to find download links for Android and iOS mobile sync clients.
Or, visit the Nextcloud download page.
Unfortunately, 2-way-sync, a.k.a bidirectional sync, isn’t fully implemented in the Android client yet. See this issue on
GitHub for the current feature’s status.

4.5 Encrypting your Nextcloud files on the server
Nextcloud includes a server side Encryption app, and when it is enabled by your Nextcloud administrator all of your
Nextcloud data files are automatically encrypted on the server. Encryption is server-wide, so when it is enabled you
cannot choose to keep your files unencrypted. You don’t have to do anything special, as it uses your Nextcloud login as
the password for your unique private encryption key. Just log out and in and manage and share your files as you normallydo, and you can still change your password whenever you want.
Its main purpose is to encrypt files on remote storage services that are connected to your Nextcloud server. This is aneasy and seamless way to protect your files on remote storage. You can share your remote files through Nextcloud in theusual way, however you cannot share your encrypted files directly from the remote service you are using, because theencryption keys are stored on your Nextcloud server, and are never exposed to outside service providers.
If your Nextcloud server is not connected to any remote storage services, then it is better to use some other form ofencryption such as file-level or whole disk encryption. Because the keys are kept on your Nextcloud server, it is possible
for your Nextcloud administrator to snoop in your files, and if the server is compromised the intruder may get access toyour files. (Read Encryption in Nextcloud to learn more.)

4.5.1 Encryption FAQ
How can encryption be disabled?
The only way to disable encryption is to run the “decrypt all” script, which decrypts all files and disables encryption.

32

Chapter 4. Files & synchronization

Nextcloud User Manual, Release latest

Is it possible to disable encryption with the recovery key?
Yes, if every user uses the file recovery key, “decrypt all” will use it to decrypt all files.
Can encryption be disabled without the user’s password?
If you don’t have the users password or file recovery key, then there is no way to decrypt all files. What’s more, runningit on login would be dangerous, because you would most likely run into timeouts.
Is it planned to move this to the next user login or a background job?
If we did that, then we would need to store your login password in the database. This could be seen as a security issue, so
nothing like that is planned.
Is group Sharing possible with the recovery key?
If you mean adding users to groups and make it magically work? No. This only works with the master key.

4.5.2 Using encryption
Nextcloud encryption is pretty much set it and forget it, but you have a few options you can use.
When your Nextcloud administrator enables encryption for the first time, you must log out and then log back in to create
your encryption keys and encrypt your files. When encryption has been enabled on your Nextcloud server you will see ayellow banner on your Files page warning you to log out and then log back in:

When you log back in it takes a few minutes to work, depending on how many files you have, and then you are returned
to your default Nextcloud page.

4.5. Encrypting your Nextcloud files on the server

33

Nextcloud User Manual, Release latest

Note: You must never lose your Nextcloud password, because you will lose access to your files. Though there is an
optional recovery option that your Nextcloud administrator may enable; see the Recovery Key Password section (below)
to learn about this.

4.5.3 Sharing encrypted files
Only users who have private encryption keys have access to shared encrypted files and folders. Users who have not yet
created their private encryption keys will not have access to encrypted shared files; they will see folders and filenames,
but will not be able to open or download the files. They will see a yellow warning banner that says “Encryption App isenabled but your keys are not initialized, please log-out and log-in again.”Share owners may need to re-share files after encryption is enabled; users trying to access the share will see a message
advising them to ask the share owner to re-share the file with them. For individual shares, un-share and re-share the file.
For group shares, share with any individuals who can’t access the share. This updates the encryption, and then the shareowner can remove the individual shares.
Recovery key password
If your Nextcloud administrator has enabled the recovery key feature, you can choose to use this feature for your account.
If you enable “Password recovery” the administrator can read your data with a special password. This feature enables theadministrator to recover your files in the event you lose your Nextcloud password. If the recovery key is not enabled, thenthere is no way to restore your files if you lose your login password.

4.5.4 Files not encrypted
Only the data in your files is encrypted, and not the filenames or folder structures. These files are never encrypted:• Old files in the trash bin.
• Image thumbnails from the Gallery app.
• Previews from the Files app.
• The search index from the full text search app.
• Third-party app data

34

Chapter 4. Files & synchronization

Nextcloud User Manual, Release latest

Only those files that are shared with third-party storage providers can be encrypted, the rest of the files may not be
encrypted.
Change private key password
This option is only available if the encryption password has not been changed by the administrator, but only the log-in
password. This can occur if your Nextcloud provider uses an external user back-end (for example, LDAP) and changed
your login password using that back-end configuration. In this case, you can set your encryption password to your new
login password by providing your old and new login password. The Encryption app works only if your login password
and your encryption password are identical.

4.6 File Sharing
Nextcloud users can share files and folders. Possible targets are:• public links• users• groups• circles• talk conversations• users or groups on federated Nextcloud servers
Note: Some options may not be available due to administrative configuration. See administrator documentation for
details.

4.6.1 Public link shares

4.7 Federated Shares
Federation Sharing allows you to mount file shares from remote Nextcloud servers, in effect creating your own cloud of
Nextclouds. You can create direct share links with users on other Nextcloud servers.

4.7.1 Creating a new Federation Share
Federation sharing is enabled by default. Follow these steps to create a new share with other Nextcloud or ownCloud
servers:
Go to your Files page and click the Share icon on the file or directory you want to share. In the sidebar enter theusername and URL of the remote user in this form: <username>@<nc-server-url>. In this example, that is
bob@cloud.example.com:

The sharee is receiving a notification in their Nextcloud, allowing them to either accept or decline the incoming share:

4.7.2 Adding a public share to your Nextcloud
Nextcloud public link share pages offer an option to add that file or folder as a federated share into your own Nextcloudinstance. Just enter your <username>@<nc-server-url> just like shown for outbound shares above:

4.8 Making anonymous uploads
You may create your own special upload directories so that other people can upload files to you without having to log into the server, and without being a Nextcloud user. They will not be allowed to see the contents of this directory, or to
make any changes. This is an excellent alternative to sending large attachments via email, using an FTP server, or using
commercial file-sharing services.

4.8.1 Setting up your own file drop
Go to Files and create or choose the folder, the anonymous upload should be made to:

a Nextcloud page with a “Click to upload” button:

This opens a file picker, and you select the file or directory you want to upload. You’re also able to just drop files into thewindow.
When your upload is completed, the filenames are listed:

Nextcloud User Manual, Release latest

4.9 Large file uploads
When uploading files through the web client, Nextcloud is limited by PHP and Apache configurations. By default, PHP
is configured for only 2 megabyte uploads. As this default upload limit is not entirely useful, we recommend that your
Nextcloud administrator increase the Nextcloud variables to sizes appropriate for users.
Modifying certain Nextcloud variables requires administrative access. If you require larger upload limits than have been
provided by the default (or already set by your administrator):• Contact your administrator to request an increase in these variables• Refer to the section in the Administration Documentation that describes how to manage file upload size limits.

4.10 Storage quotaYour Nextcloud administrator has the option to set a storage quota on users. Look at your the Personal page to see what
your quota is, and how much you have used.

It may be helpful to understand how your quota is calculated.
Metadata (thumbnails, temporary files, cache, and encryption keys) takes up about 10% of disk space, but is not counted
against user quotas. Some apps store information in the database, such as the Calendar and Contacts apps. This data is
excluded from your quota.
When other users share files with you, the shared files count against the original share owner’s quota. When you share afolder and allow other users or groups to upload files to it, all uploaded and edited files count against your quota. Whenyou re-share files shared with you, the re-share still counts against the quota of the original share owner.
Encrypted files are a little larger than unencrypted files; the unencrypted size is calculated against your quota.
Deleted files that are still in the trash bin do not count against quotas. The trash bin is set at 50% of quota. Deleted fileaging is set at 30 days. When deleted files exceed 50% of quota then the oldest files are removed until the total is below
50%.
Note: Your administrator may have configured the trash bin retention period to override the storage space management.
See administrator documentation for more details.

44

Chapter 4. Files & synchronization

Nextcloud User Manual, Release latest

When version control is enabled, the older file versions are not counted against quotas.
If you create a public share via URL and allow uploads, any uploaded files count against your quota.

4.11 Version control
Nextcloud supports simple version control system for files. Versioning creates backups of files which are accessible via
the Versions tab on the Details sidebar. This tab contains the history of the file where you can roll back a file to any
previous version. Changes made at intervals greater than two minutes are saved in data/[user]/files_versions.

To restore a specific version of a file, click the circular arrow to the right. Click on the timestamp to download it.
The versioning app expires old versions automatically to make sure that the user doesn’t run out of space. This pattern isused to delete old versions:• For the first second we keep one version• For the first 10 seconds Nextcloud keeps one version every 2 seconds
4.11. Version control

45

Nextcloud User Manual, Release latest• For the first minute Nextcloud keeps one version every 10 seconds• For the first hour Nextcloud keeps one version every minute• For the first 24 hours Nextcloud keeps one version every hour
• For the first 30 days Nextcloud keeps one version every day• After the first 30 days Nextcloud keeps one version every week
The versions are adjusted along this pattern every time a new version gets created.
The version app never uses more than 50% of the user’s currently available free space. If the stored versions exceed thislimit, Nextcloud deletes the oldest versions until it meets the disk space limit again.

4.11.1 Naming a version
You can give a name to a version.

When a version has a name, it will be excluded from the automatic expiration process.

4.11.2 Deleting a version
You can also manually delete a version without waiting for the automatic expiration process.

4.12 Projects
Users can associate files, chats and other items with each other in projects. The various apps will present these items in alist, allowing users to immediately jump to them. Projects are Nextcloud wide. When a user shares a file that is part of a
project, the share recipient can see that project, too. A click on any of the items in a project leads right to it, be it a chat,a file or a task.

4.12.1 Create a new project
A new project can be created by linking two items together. Start off by opening a file or folders sharing sidebar.
Click Add to a project and select the type of item you want to link with the current file/folder. A selector will open thatallows you selecting a Talk conversation for example.
Once the item has been selected a new project is being created and listed in the sharing tab of the sidebar. The same
project will also appear in the sharing sidebar of the linked items.
The list entry shows quick links to a limited number of items. By opening the context menu, the project can be renamed
and the full list of items can be expanded.

4.12.2 Adding more entries to a project
If another item should be added to an already existing project this can be done by searching for the project name in the

4.14 Using Federation Shares
Federation Sharing allows you to mount file shares from remote Nextcloud servers, in effect creating your own cloud of
Nextclouds. You can create direct share links with users on other Nextcloud servers.

4.14.1 Creating a new Federation Share
Federation sharing is enabled on new or upgraded Nextcloud installations by default. Follow these steps to create a newshare with other Nextcloud or ownCloud 9+ servers:
1. Go to your Files page and click the Share icon on the file or directory you want to share. In the sidebar enter theusername and URL of the remote user in this form: <username>@<oc-server-url>. The form automaticallyconfirms the address that you type and labels it as “remote”. Click on the label.

2. When your local Nextcloud server makes a successful connection with the remote Nextcloud server you’ll see a confirmation. Your only share option is Can edit.
Click the Share button anytime to see who you have shared your file with. Remove your linked share anytime by clicking
the trash can icon. This only unlinks the share, and does not delete any files.

4.14.2 Creating a new Federated Cloud Share via email
Use this method when you are sharing with users on ownCloud 8.x and older.
What if you do not know the username or URL? Then you can have Nextcloud create the link for you and email it to yourrecipient.

When your recipient receives your email they will have to take a number of steps to complete the share link. First theymust open the link you sent them in a Web browser, and then click the Add to your Nextcloud button.
The Add to your Nextcloud button changes to a form field, and your recipient needs to enter the URL of their Nextcloudor ownCloud server in this field and press the return key, or click the arrow.

CHAPTERFIVEGROUPWARE

Nextcloud Groupware is a bundle of apps which is consisting of an Mail-client (IMAP/POP3) and a Calendar andContacts server (CalDAV/CardDAV) with the respective web interfaces.
We complete those productivity tools with Deck, a project management tool which allows you to create Kanban-style taskboards and share them with your team.
You can find out more about Nextcloud Groupware on our website.

5.1 Using the Contacts app
The Contacts app is not enabled by default in Nextcloud latest and needs to be installed separately from our App Store.
The Nextcloud Contacts app is similar to other mobile contact applications, but with more functionality. Let’s run throughbasic features that will help you maintain your address book in the application.
Below, you will learn how to add contacts, edit or remove contacts, upload a contact picture and manage your address
books.

5.1.1 Adding Contacts
When you first access the Contacts app, the system address book containing all users on the instance you are allowed tosee, plus an empty default address book becomes available:
To add contacts into your address book, you can use one of the following methods:• Import contacts using a Virtual Contact File (VCF/vCard) file
• Add contacts manually
The fastest way to add a contact is to use a Virtual Contact File (VCF/vCard) file.
Importing Virtual Contacts
To Import Contacts Using a VCF/vCard File:
1. On top left of the screen you have “Import contacts” button that is shown only when you don’t have any contacts
yet.
2. Find “Settings” at the bottom of the left sidebar, next to the gear button:

3. Click the gear button. The Contacts app “Import” button will appear:55

there.
See Groupware for more details about syncing your address books with iOS, macOS, Thunderbird and other CardDAV
clients.

5.1.3 Circles
Informal collaboration takes place within organizations: an event to organize for a few weeks, a short ideation session
between members from differents entities, workshops, a place to joke around and support team building, or simply invery organic organizations where formal structure is kept to a minimum.
For all these reasons, Nextcloud supports Circles, a feature embedded in the Contacts app, where every user is able tocreate its own circle, a user-defined aggregate of accounts. Circles can be used later on to share files and folders, added
to Talk conversations, like a regular group.

5.1. Using the Contacts app

Circles support 4 types of roles:• Member• Moderator• Admin can configure circle options (+moderator permissions)• OwnerMemberMember is the role with the lowest permissions. A member can only access the resources shared with the circle, and viewthe members of the circle.
Moderator
In addition to member permissions, a moderator can invite, confirm invitations and manage members of the circle.
Admin
In addition to moderator permissions, an admin can configure circle options.
Owner
In addition to admin permissions, an owner can transfer the circle ownership to another member of the circle. There canbe only one single owner per circle.

Circle options
Various self-explanatory options are available to configure a circle, to manage invites and membership, visibility of thecircle, allowance of other circle membership and password protection.
Shared items
New in version 5.5.

Items that are shared between two contacts will be displayed in the contact app. This includes media, calendar events, chatrooms, and shared deck cards, all of which will be visible in the contact details. This functionality is limited to contacts
listed in the system address book. Currently, our system only supports shared items between two contacts.

Sharing calendars
You may share your calendar with other users or groups. Calendars may be shared with write access or read-only. Whensharing a calendar with write access, users with whom the calendar is shared will be able to create new events into thecalendar as well as edit and delete existing ones.
Note: Calendar shares currently cannot be accepted or rejected. If you want to stop having a calendar that someone
shared with you, you can click on the 3-dot menu next to the calendar in the calendar list and click on “Unshare from me”.
To restore a share, the calendar can be reshared again, either for the whole group, resetting all unshares, or for a single
user.

Publishing a calendar
Calendars can be published through a public link to make them viewable (read-only) to external users. You may create apublic link by opening the share menu for a calendar and clicking on « + » next to « Share link ». Once created you cancopy the public link to your clipboard or send it through email.
There’s also an « embedding code » that provides an HTML iframe to embed your calendar into public pages.
Multiple calendars can be shared together by adding their unique tokens to the end of an embed link. Individual tokens
can be found at the end of each calendar’s public link. The full address will look like https://cloud.example.
com/index.php/apps/calendar/embed/<token1>-<token2>-<token3>
To change the default view or date of an embedded calendar, you need to provide a URL that looks like https://cloud.example.com/index.php/apps/calendar/embed/<token>/<view>/<date>. In this url
you need to replace the following variables:• <token> with the calendar’s token,• <view> with one of dayGridMonth, timeGridWeek, timeGridDay, listMonth, listWeek,
listDay. The default view is dayGridMonth and the normally used list is listMonth,• <date> with now or any date with the following format <year>-<month>-<day> (e.g. 2019-12-28).
On the public page, users are able to get the subscription link for the calendar and export the whole calendar directly.
Calendar Widget
You can embed your calendars into supported apps like Talk, Notes, etc… by either sharing the public link to makethe embed viewable (read-only) to all users or by using the internal link to make it private.
Subscribe to a Calendar
You can subscribe to iCal calendars directly inside of your Nextcloud. By supporting this interoperable standard (RFC5545) we made Nextcloud calendar compatible to Google Calendar, Apple iCloud and many other calendar-servers you
can exchange your calendars with, including subscription links from calendar published on other Nextcloud instances, as
described above.
1. Click on + New calendar in the left sidebar
2. Click on + New subscription from link (read-only)

You can also export, duplicate or delete an event from the basic editor.

Invite attendees to an event
You may add attendees to an event to let them know they’re invited. They will receive an email invitation and will be able
to confirm or cancel their participation to the event. Attendees may be other users on your Nextcloud instances, contacts
in your address books and direct email addresses. You may also change the level of participation per attendees, or disable
the email information for a specific attendee.
Changed in version 25: Attendee email response links no longer offer inputs to add a comment or invite additional guests
to the event.
Tip: When adding other Nextcloud users as attendees to an event, you may access their free-busy information if available,
helping you determine when the best time slot for your event is. Set your working hours to let others know when you areavailable. Free-busy information is only available for other users on the same Nextcloud instance.

Attention: Only the calendar owner can send out invitations. The sharees are not able to do that, whether they havewrite access to the event’s calendar or not.

Attention: The server administration needs to setup the e-mail server in the Basic settings tab, as this mailwill be used to send invitations.

Assign rooms and resources to an event
Similar to attendees you can add rooms and resources to your events. The system will make sure that each room andresource is booked without conflict. The first time a user adds the room or resource to an event, it will show as accepted.
Any further events at overlapping times will show the room or resource as rejected.
Note: Rooms and resources are not managed by Nextcloud itself and the Calendar app will not allow you to add orchange a resource. Your Administrator has to install and possibly configure resource back ends before you can use themas a user.

Add attachments to events
You can import attachments to your events either by uploading them or adding them from files

Note: Attachments can be added while creating new events or editing existent ones. Newly uploaded files will be savedin files by default in the calendar folder in the root directory.
You can change the attachment folder by going to Calendar settings in the bottom left corner and changing
default attachments location.

Set up reminders
You can set up reminders to be notified before an event occurs. Currently supported notification methods are:• Email notifications• Nextcloud notifications
You may set reminders at a time relative to the event or at a specific date.
Note: Only the calendar owner and people or groups with whom the calendar is shared with write access will get
notifications. If you don’t get any notifications but think you should, your Administrator could also have disabled this foryour server.

Note: If you synchronize your calendar with mobile devices or other 3rd-party clients, notifications may also show up
there.

Add recurring options
An event may be set as “recurring”, so that it can happen every day, week, month or year. Specific rules can be added to
set which day of the week the event happens or more complex rules, such as every fourth Wednesday of each month.
You can also tell when the recurrence ends.

Trash binIf you delete events, tasks or a calendar in Calendar, your data is not gone yet. Instead, those items will be collected ina trash bin. This offers you to undo a deletion. After a period which defaults to 30 days (your administration may havechanged this setting), those items will be deleted permanently. You can also permanently delete items earlier if you wish.
The Empty trash bin buttons will wipe all trash bin contents in one step.
Tip: The trash bin is only accessible from the Calendar app. Any connected application or app won’t be able to display
its contents. However, events, tasks and calendars deleted in connected applications or app will also end up in the trashbin.

Automated User Status
When you have a calendar event scheduled that has a “BUSY” status, your user status will be automatically set to “In ameeting” unless you have set yourself to “Do Not Disturb” or “Invisible”. You can overwrite the status with a custom
message any time, or set your calendar events to “FREE”. Calendars that are transparent will be ignored.

5.2.6 Appointments
As of Calendar v3 the app can generate appointment slots which other Nextcloud users but also people without an accounton the instance can book. Appointments offer fine-granular control over when you are possibly free to meet up. This caneliminate the need to send emails back and forth to settle on a date and time.
In this section we’ll use the term organizer for the person who owns the calendar and sets up appointment slots. The
attendee is the person who books one of the slots.
Creating an appointment configuration
As an organizer of appointments you open the main Calendar web UI. In the left sidebar you’ll find a section for appointments, were you can open the dialogue to create a new one.
One of the basic infos of every appointment is a title describing what the appointment is about (e.g. “One-on-one” when an
organizer wants to offer colleagues a personal call), where an appointment will take place and a more detailed descriptionof what this appointment is about.
The duration of the appointment can be picked from a predefined list. Next, you can set the desired increment. The
increment is the rate at which possible slots are available. For example, you could have one hour long slots, but you
give them away at 30 minute increments so an attendee can book at 9:00AM but also at 9:30AM. Optional infos aboutlocation and a description give the attendees some more context.Every booked appointment will be written into one ofyour calendars, so you can chose which one that should be. Appointments can be public or private. Public appointments
can be discovered through the profile page of a Nextcloud user. Private appointments are only accessible to the people
who receive the secret URL.

Note: Only slots that do not conflict with existing events in your calendars will be shown to attendees.
The organizer of an appointment can specify at which times of the week it’s generally possible to book a slot. This could
be the working hours but also any other customized schedule.

Some appointments require time to prepare, e.g. when you meet at a venue and you have to drive there. The organizer canchose to select a time duration that must be free. Only slots that do not conflict with other events during the preparation
time will be available. Moreover there is the option to specify a time after each appointment that has to be free. To preventan attendee from booking too short notice it’s possible to configure how soon the next possible appointment might takeplace. Setting a maximum number of slots per day can limit how many appointments are possibly booked by attendees.
The configured appointment will then be listed in the left sidebar. Via the three dot menu, you can preview the appointment. You can copy the link to the appointment and share it with your target attendees, or let them discover your public
appointment via the profile page. You can also edit or delete the appointment configuration.
Booking an appointment
The booking page shows an attendee the title, location, description and length of an appointment. For a selected day
there will be a list with all the possible time slots. On days with no available slots, too many conflicts or a reached daily
maximum limit of already booked appointments, the list might be empty.
For the booking, attendees have to enter a name and an email address. Optionally they can also add a comment.
When the booking was successful, a confirmation dialogue will be shown to the attendee.
To verify that the attendee email address is valid, a confirmation email will be sent to them.

Only after the attendee clicks the confirmation link from the email the appointment booking will be accepted and forwarded to the organizer.
The attendee will receive another email confirming the details of their appointment.
Note: If a slot has not been confirmed, it will still show up as bookable. Until then the time slot might also be bookedby another user who confirms their booking earlier. The system will detect the conflict and offer to pick a new time slot.

Working with the booked appointment
Once the booking is done, the organizer will find an event in their calendar with the appointment details and the attendee.
If the appointment has the setting “Add time before event” or “Add time after the event” enabled, they will show up as
separate events in the calendar for the organizer.
As with any other event that has attendees, changes and cancellations will trigger a notification to the attendee’s email.
If attendees wish to cancel the appointment they have to get in contact with the organizer, so that the organizer can cancel
or even delete the event.

The outbox is only visible when there is a message waiting to be handled by the outbox.
You can re- open the composer for a message in the outbox any time before the “send”- operation is triggered.
Note: When an error occurs during sending, three error messages are possible:
Could not copy to “Sent” mailbox
The mail was sent but couldn’t be copied to the “Sent” mailbox. This error will be handled by the outbox and the
copy operation will be tried again.
Mail server error
Sending was unsuccessful with a state than can be retried (ex: the SMTP server couldn’t be reached). The outbox
will retry sending the message.
Message could not be sent
Sending might or might not have failed. The mail server can’t tell us the state of the message. Since the Mail
app has no way to determine the state of the message (sent or unsent) the message will stay in the outbox and theaccount user has to decide how to proceed.

TALK

Nextcloud Talk offers audio/video and text chat integrated in Nextcloud. It offers a web interface as well as mobile apps.
You can find out more about Nextcloud Talk on our website.

6.1 Basics of Nextcloud Talk
Nextcloud Talk lets you chat and have video calls on your own server.
Chats and calls take place in conversations. You can create any number of conversations. There are two kinds of conversations:
1. One-on-one conversations. This is where you have a private chat or call with another Talk user. You can’t add
other people to this conversation or share it with a link. You start a direct one-on-one chat by looking for anotheruser in the search bar and then clicking their name.
2. Group conversations. Besides the person who created the conversation, a group conversation can have any numberof people in it. A group conversation can be shared publicly with a link, so external guest users can join a call. It
can also be listed, so other people on your Nextcloud server can join the conversation.

133

Nextcloud User Manual, Release latest

6.1.1 Creating a chat
You can create a direct, one-on-one chat by searching for the name of a user, a group or a team and clicking it. For asingle user, a conversation is immediately created and you can start your chat. For a group or circle you get to pick a nameand settings before you create the conversation and add the participants.

If you want to create a custom group conversation, click the button next to the search field and filters button and then on

Some administrators decide to share their global address book with other Nextcloud instances (so called Trusted Servers)or even with the wider world. This is helpful when two instances want to work closely together, or when people want to
use Nextcloud as a virtual telephone book for others to browse. It also allows searching for contacts, creating shares andmuch more.
You can change what personal data of yours is shared by setting the scope of your data. Clicking on the lock icon will
open the following dropdown next to each entry:

If you set your data to Private, nobody but you will be able to see it.
If you set your data to Local, all logged in users within your Nextcloud instance will be able to see the information, but
noone outside of it.
If you set your data to Federated, the trusted server(s) which are added by your administrator will be able to see thisdata, in addition to all logged in users.
If you set your data to Global, anyone can see your data. For some use cases this is wanted. Someone with a public facingrole such as marketing or sales might want to share their contact with a wide variety of connections which might not be

USING TWO-FACTOR AUTHENTICATION

Two-factor authentication (2FA) is a way to protect your Nextcloud account against unauthorized access. It works byrequiring two different ‘proofs’ of your identity. For example, something you know (like a password) and something you
have like a physical key. Typically, the first factor is a password like you already have and the second can be a text message
you receive or a code you generate on your phone or another device (something you have). Nextcloud supports a varietyof 2nd factors and more can be added.
Once a two-factor authentication app has been enabled by your administrator you can enable and configure it in Setting
your preferences. Below you can see how.

9.1 Configuring two-factor authentication
In your Personal Settings look up the Second-factor Auth setting. In this example this is TOTP, a Google Authenticator
compatible time-based code:
You will see your secret and a QR code which can be scanned by the TOTP app on your phone (or another device).
Depending on the app or tool, type in the code or scan the QR and your device will show a login code which changes
every 30 seconds.

9.2 Recovery codes in case you lost your 2nd factor
You should always generate backup codes for 2FA. If your 2nd factor device gets stolen or is not working, you will beable to use one of these codes to unlock your account. It effectively functions as a backup 2nd factor. To get the backup
codes, go to your Personal Settings and look under Second-factor Auth settings. Choose Generate backup codes:
You will then be presented with a list of one-time-use backup codes:
You should put these codes in a safe spot, somewhere you can find them. Don’t put them together with your 2nd factor
like your mobile phone but make sure that if you lose one, you still have the other. Keeping them at home is probably thebest thing to do.

9.3 Logging in with two-factor authentication
After you have logged out and need to log in again, you will see a request to enter the TOTP code in your browser. If
you enable not only the TOTP factor but another one, you will see a selection screen on which you can choose two-factor
method for this login. Select TOTP:

Now, just enter your code:
If the code was correct you will be redirected to your Nextcloud account.
Note: Since the code is time-based, it’s important that your server’s and your smartphone’s clock are almost in sync. A
time drift of a few seconds won’t be a problem.

9.4 Using two-factor authentication with hardware tokens
You can use two-factor authentication based on hardware tokens. The following devices are known to work:• TOTP based:– Nitrokey Pro– Nitrokey Storage• FIDO U2F based:

186

Chapter 9. Using two-factor authentication

Nextcloud User Manual, Release latest– Nitrokey FIDO U2F

9.5 Using client applications with two-factor authentication
Once you have enabled 2FA, your clients will no longer be able to connect with just your password unless they also havesupport for two-factor authentication. To solve this, you should generate device specific passwords for them. See Manage
connected browsers and devices for more information on how to do this.

9.6 Considerations
If you use WebAuthn to login to your Nextcloud be sure to not use the same token for 2FA. As this would mean you areagain only using a single factor.

At the bottom of the list you find a button to create a new device-specific password. You can choose a name to identify
the token later. The generated password is used for configuring the new client. Ideally, generate individual tokens forevery device you connect to your account, so you can disconnect those individually if necessary:
Note: You have only access to the device password when creating it, Nextcloud will not save the plain password, hence
it’s recommended to enter the password on the new client immediately.

Note: If you are Using two-factor authentication for your account, device-specific passwords are the only way to configure
clients. The server will deny connections of clients using your login password then.
