Could the file area do with a tree folder structure. I am of the thinking that the file area could be used as a document repository and would be structured better for the users if it were more in a tree structure.
eg
folder structure for IT personell in the IT Team would look like (no exact thought into folder names):
Hardware -> Purchases
Hardware -> Systems -> Desktops
Hardware -> Systems -> Servers
Software -> Antivirus
There are many uses for a structural approach and maybe the file area isnt the place for it. Maybe a new App entirely.
