To install your cloud directory as a filesystem, you first need davfs2 installed. 99% of the time, this will be included in your distributions repositories. In Debian
`apt-get install davfs2`
If you want to let normal users mount the filesystem
`dpkg-reconfigure davfs2`
and select "yes" at the prompt.
Now you need to add any user you want to be able to mount dav to the davfs2 group
Where {{Username}} is your username at your Red hub, example.com is the URL of your hub, /mount/point is the location you want to mount the cloud, and {{DesktopUser}} is the user you log in to one your computer. Note that if you are mounting as a normal user (not root) the mount point must be in your home directory.
You can now find your cloud at /home/bob/cloud and use it as though it were part of your local filesystem - even if the applications you are using have no dav support themselves.
