Accessing ownCloud Files Using WebDAV
ownCloud fully supports the WebDAV protocol, and you can connect and synchronize with your ownCloud files over WebDAV. In this chapter you will learn how to connect Linux, Mac OS X, Windows, and mobile devices to your ownCloud server via WebDAV. Before we get into configuring WebDAV, let’s take a quick look at the recommended way of connecting client devices to your ownCloud servers.
The recommended method for keeping your desktop PC synchronized with your ownCloud server is by using the ownCloud Desktop Client. You can configure the ownCloud client to save files in any local directory you want, and you choose which directories on the ownCloud server to sync with. The client displays the current connection status and logs all activity, so you always know which remote files have been downloaded to your PC, and you can verify that files created and updated on your local PC are properly synchronized with the server.
The recommended method for syncing your ownCloud server with Android and Apple iOS devices is by using the ownCloud mobile apps.
To connect to your ownCloud server with the ownCloud mobile apps, use the base URL and folder only:
In addition to the mobile apps provided by ownCloud, you can use other apps to connect to ownCloud from your mobile device using WebDAV. WebDAV Navigator is a good (proprietary) app for Android devices, iPhones, and BlackBerry devices. The URL to use on these is:
If you prefer, you may also connect your desktop PC to your ownCloud server by using the WebDAV protocol rather than using a special client application. Web Distributed Authoring and Versioning (WebDAV) is a Hypertext Transfer Protocol (HTTP) extension that makes it easy to create, read, and edit files on Web servers. With WebDAV you can access your ownCloud shares on Linux, Mac OS X and Windows in the same way as any remote network share, and stay synchronized.
|In the following examples, You must adjust example.com/ to the URL of your ownCloud server installation.|
You can access files in Linux operating systems using the following methods.
davs:// protocol to connect the Nautilus file manager to your
If your server connection is not HTTPS-secured, use
To access your ownCloud files using the Dolphin file manager in KDE, use
You can create a permanent link to your ownCloud server:
Open Dolphin and click "Network" in the left hand "Places" column.
Click on the icon labeled Add a Network Folder. The resulting dialog should appear with WebDAV already selected.
If WebDAV is not selected, select it.
Enter the following settings:
Name: The name you want to see in the Places bookmark, for example ownCloud.
User: The ownCloud username you used to log in, for example admin.
Server: The ownCloud domain name, for example example.com (without http:// before or directories afterwards).
Folder – Enter the path
(Optional) Check the "Create icon checkbox" for a bookmark to appear in the Places column.
(Optional) Provide any special settings or an SSL certificate in the "Port & Encrypted" checkbox.
You can create WebDAV mounts from the Linux command line. This is useful if you prefer to access ownCloud the same way as any other remote filesystem mount. The following example shows how to create a personal mount and have it mounted automatically every time you log in to your Linux computer.
davfs2WebDAV filesystem driver, which allows you to mount WebDAV shares just like any other remote filesystem. Use this command to install it on Debian/Ubuntu:
apt-get install davfs2
Use this command to install it on CentOS, Fedora, and openSUSE:
yum install davfs2
Add yourself to the
usermod -aG davfs2 <username>
Then create an
ownclouddirectory in your home directory for the mountpoint, and
.davfs2/for your personal configuration file:
mkdir ~/owncloud mkdir ~/.davfs2
cp /etc/davfs2/secrets ~/.davfs2/secrets
Set yourself as the owner and make the permissions read-write owner only:
chown <username>:<username> ~/.davfs2/secrets chmod 600 ~/.davfs2/secrets
Add your ownCloud login credentials to the end of the
secretsfile, using your ownCloud server URL and your ownCloud username and password:
example.com/owncloud/remote.php/dav/files/USERNAME/ <username> <password>
Add the mount information to
example.com/owncloud/remote.php/dav/files/USERNAME/ /home/<username>/owncloud davfs user,rw,auto 0 0
Then test that it mounts and authenticates by running the following command. If you set it up correctly you won’t need root permissions:
You should also be able to unmount it:
Now every time you login to your Linux system your ownCloud share should
automatically mount via WebDAV in your
~/owncloud directory. If you
prefer to mount it manually, change
If you experience trouble when you create a file in the directory, edit
/etc/davfs2/davfs2.conf and add:
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
/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:
|The Mac OS X Finder suffers from a series of implementation problems and should only be used if the ownCloud server runs on Apache and mod_php, or NGINX 1.3.8+.|
To access files through the Mac OS X Finder:
Choose Go > Connect to Server.
The "Connect to Server" window opens.
Specify the address of the server in the Server Address field.
For example, the URL used to connect to the ownCloud server from the Mac OS X Finder is:
The device connects to the server.
For added details about how to connect to an external server using Mac OS X, check the vendor documentation
It is best to use a suitable WebDAV client from the WebDAV Project page .
If you must use the native Windows implementation, you can map ownCloud to a new drive. Mapping to a drive enables you to browse files stored on an ownCloud server the way you would files stored in a mapped network drive.
Using this feature requires network connectivity. If you want to store your files offline, use the ownCloud Desktop Client to sync all files on your ownCloud to one or more directories of your local hard drive.
|Prior to mapping your drive, you must permit the use of Basic Authentication in the Windows Registry. The procedure is documented in KB841215 and differs between Windows XP/Server 2003 and Windows Vista/7. Please follow the Knowledge Base article before proceeding, and follow the Vista instructions if you run Windows 7.|
The following example shows how to map a drive using the command line. To map the drive:
Open a command prompt in Windows.
Enter the following line in the command prompt to map to the computer Z drive, where <drive_path> is the URL to your ownCloud server:
net use Z: https://<drive_path>/remote.php/dav/files/USERNAME/ /user:youruser yourpassword
net use Z: https://example.com/owncloud/remote.php/dav/files/USERNAME/ /user:youruser yourpassword
The computer maps the files of your ownCloud account to the drive letter Z.
|Though not recommended, you can also mount the ownCloud 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\owncloud\remote.php\dav /user:youruser yourpassword
To map a drive using the Microsoft Windows Explorer:
Migrate to your computer in Windows Explorer.
Right-click on Computer entry and select Map network drive… from the drop-down menu.
Choose a local network drive to which you want to map ownCloud.
Specify the address to your ownCloud instance, followed by /remote.php/dav/files/USERNAME/.
|For SSL protected servers, check Reconnect at logon to ensure that the mapping is persistent upon subsequent reboots. If you want to connect to the ownCloud server as a different user, check Connect using different credentials.|
Windows Explorer maps the network drive, making your ownCloud instance available.
Cyberduck is an open source FTP and SFTP, WebDAV, OpenStack Swift, and Amazon S3 browser designed for file transfers on Mac OS X and Windows.
|This example uses Cyberduck version 4.2.1.|
To use Cyberduck:
Specify a server without any leading protocol information. For example:
Specify the appropriate port. The port you choose depends on whether or not your ownCloud server supports SSL. Cyberduck requires that you select a different connection type if you plan to use SSL. For example:
80 (for WebDAV) 443 (for WebDAV (HTTPS/SSL))
Use the `More Options' drop-down menu to add the rest of your WebDAV URL into the `Path' field. For example:
Now Cyberduck enables file access to the ownCloud server.
ownCloud provides the possibility to access public shares over WebDAV.
To access the public share, open:
in a WebDAV client, use the share token as username and the (optional) share password as password.
The Windows WebDAV Client might not support Server Name Indication (SNI) on encrypted connections. If you encounter an error mounting an SSL-encrypted ownCloud instance, contact your provider about assigning a dedicated IP address for your SSL-based server.
The Windows WebDAV Client might not support TSLv1.1 / TSLv1.2 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.
You receive the following error message: Error 0x800700DF: The file size exceeds the limit allowed and cannot be saved.
Windows limits the maximum size a file transferred from or to a WebDAV share may have. You can increase the value FileSizeLimitInBytes in HKEY_LOCAL_MacHINE\SYSTEM\CurrentControlSet\Services\WebClient\Parameters by clicking on Modify.
To increase the limit to the maximum value of 4GB, select Decimal, enter a value of 4294967295, and reboot Windows or restart the WebClient service.
Known problems and their solutions are documented in the KB2123563 article.
Go to the your ownCloud instance via your favorite Web browser.
Click through until you get to the certificate error in the browser status line.
View the cert, then from the Details tab, select Copy to File.
Save to the desktop with an arbitrary name, for example
Start, Run, MMC.
File, Add/Remove Snap-In.
Select Certificates, Click Add, My User Account, then Finish, then OK.
Dig down to Trust Root Certification Authorities, Certificates.
Right-Click Certificate, Select All Tasks, Import.
Select the Save Cert from the Desktop.
Select Place all Certificates in the following Store, Click Browse,
Check the Box that says Show Physical Stores, Expand out Trusted Root Certification Authorities, and select Local Computer there, click OK, Complete the Import.
Check the list to make sure it shows up. You will probably need to Refresh before you see it. Exit MMC.
Open Browser, select Tools, Delete Browsing History.
Select all but In Private Filtering Data, complete.
Go to Internet Options, Content Tab, Clear SSL State.
Close browser, then re-open and test.
You cannot download more than 50 MB or upload large Files when the upload takes longer than 30 minutes using Web Client in Windows 7.
Workarounds are documented in the KB2668751 article.
Make Windows service WebClient start automatically:
Open Control Panel.
Go to Administrative Tools.
Find WebClient service.
Right-click on it and choose Properties.
Select Startup type: Automatic.
Click OK button.
Or in command prompt (as Admin):
sc config "WebClient" start=auto sc start "WebClient"

Since WebDAV is an extension of HTTP cURL can be used to script file operations.
To create a folder with the current date as name:
$ curl -u user:pass -X MKCOL "https://example.com/owncloud/remote.php/dav/files/USERNAME/$(date '+%d-%b-%Y')"
To upload a file
error.log into that directory:
$ curl -u user:pass -T error.log "https://example.com/owncloud/remote.php/dav/files/USERNAME/$(date '+%d-%b-%Y')/error.log"
To move a file:
$ curl -u user:pass -X MOVE --header 'Destination: https://example.com/owncloud/remote.php/dav/files/USERNAME/target.jpg' https://example.com/owncloud/remote.php/dav/files/USERNAME/source.jpg
To get the properties of files in the root folder:
$ curl -X PROPFIND -H "Depth: 1" -u user:pass https://example.com/owncloud/remote.php/dav/files/USERNAME/ | xml_pp <?xml version="1.0" encoding="utf-8"?> <d:multistatus xmlns:d="DAV:" xmlns:oc="http://owncloud.org/ns" xmlns:s="http://sabredav.org/ns"> <d:response> <d:href>/owncloud/remote.php/dav/files/USERNAME/</d:href> <d:propstat> <d:prop> <d:getlastmodified>Tue, 13 Oct 2015 17:07:45 GMT</d:getlastmodified> <d:resourcetype> <d:collection/> </d:resourcetype> <d:quota-used-bytes>163</d:quota-used-bytes> <d:quota-available-bytes>11802275840</d:quota-available-bytes> <d:getetag>"561d3a6139d05"</d:getetag> </d:prop> <d:status>HTTP/1.1 200 OK</d:status> </d:propstat> </d:response> <d:response> <d:href>/owncloud/remote.php/dav/files/USERNAME/welcome.txt</d:href> <d:propstat> <d:prop> <d:getlastmodified>Tue, 13 Oct 2015 17:07:35 GMT</d:getlastmodified> <d:getcontentlength>163</d:getcontentlength> <d:resourcetype/> <d:getetag>"47465fae667b2d0fee154f5e17d1f0f1"</d:getetag> <d:getcontenttype>text/plain</d:getcontenttype> </d:prop> <d:status>HTTP/1.1 200 OK</d:status> </d:propstat> </d:response> </d:multistatus>
To get the file id of a file, regardless of location, you need to make a PROPFIND request. This request requires two things:
A PROPFIND XML element in the body of the request method.
The path to the file that you want to find out more about
Here’s an example PROPFIND XML element, which we’ll store as
<?xml version="1.0"?> <a:propfind xmlns:a="DAV:" xmlns:oc="http://owncloud.org/ns"> <!-- retrieve the file's id --> <a:prop><oc:fileid/></a:prop> </a:propfind>
|You could pass this directly to the Curl request. However, it can often be easier to create, maintain, and to share, if it’s created in a standalone file.|
With the file created, make the request by running the following Curl command:
curl -u username:password -X PROPFIND \ -H "Content-Type: text/xml" \ --data-binary "@propfind-fileid.xml" \ 'http://localhost/remote.php/dav/files/admin/Photos/San%20Francisco.jpg'
This will return an XML response payload similar to the following example. It contains the relative path to the file and the fileid of the file.
<?xml version="1.0"?> <d:multistatus xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns" xmlns:cal="urn:ietf:params:xml:ns:caldav" xmlns:cs="http://calendarserver.org/ns/" xmlns:card="urn:ietf:params:xml:ns:carddav" xmlns:oc="http://owncloud.org/ns"> <d:response> <d:href>/remote.php/dav/files/admin/Photos/San%20Francisco.jpg</d:href> <d:propstat> <d:prop> <oc:fileid>4</oc:fileid> </d:prop> <d:status>HTTP/1.1 200 OK</d:status> </d:propstat> </d:response> </d:multistatus>
The example above’s been formatted for readability, using
