Recommendations for a WebDAV client
In Nautilus (the file browser), select File > Connect to ... and select WebDAV. Enter the information you need, such as a host name, a directory, port and username. Check the box to create a bookmark, and you'll find it in your Files and Folder lense and in the left pane in Nautilus.
You'll be able to use your WebDAV share as if it were a local folder.
On Ubuntu 14.04:
1) Open Nautilus (File manager)
2) Click on 'Connect to Server'
3) As server address enter:
davs://<username>@<webdav_address>
It is important that webdav_address doesn't contain the protocol. So for example if your web url is: https://example.com/webdav
and your username is alice, the corresponding address for the server will be:
davs://[email protected]/webdav
All of the server connections are handled in the same way in nautilus. You fill out the data for nautilus to connect to the remote server at which point it will be added as a bookmark to the bookmarked folders list.
The first time you try to connect to the server if it is password protected you will be asked to provide the password and you will be asked whether you want to save the password permanently, for the current session or forget immediately. Once the server has been mounted it can be browsed like any other folder on your system.
Hope this helps
