Not really what I said, if auditing is turned off (which it likely is) then if a student gained access to a folder, the admins would not be able to trace it. Now if the student opened and change something in the folder, the properties on the file would be updated with the students information and they could get busted like that.
So even if auditing is turned off, and a student edits a file, the admins could see that the student edited it?
