Overall storage space used (incl. recycle bin)

Dear NC community,

I there a simple way or an app to see the overall disk space used by all users?
The only overview I have in NC13 is the user by user overview, which doesn’t include data in the recycle bin.


The reasoning behind my question is, if you are using a Webspace or Cloud Provider as a host you might have storage limitations and you wanna make sure you are not exceeding storage limits.

Maybe there is a possibility to define an overall maximum for storage?
