This script empty every trash of the system, remove old account listed by AccountsToDelete variable and delete main temp files of every users. 

Useful when someone complains about "disk space" on a computer shared by several users.

But be careful! This script is quite straightforward and is not still fully tested.


Put autoit3.exe and autoit3 Include\ dir in CLIENT_CONFIG dir.
