The sharing feature in the WebInterface is an option you can enable in the [user manager] for specific [folders|VFS].  Just like the upload, download delete permissions, you can also add 'share'.

A shared item is by default copied to a temp location.  A new random username and password is generated with a set time for when it will expire and that user and its files will be removed.  You fill out an email form of the notice you want to send to the user and they will get a link giving them direct access to the files.

If you enable the advanced checkbox, there are a few other options that will be enabled that you can also use.
