If they have an Administrative account, they can see anything you can.
This doesnt do much at all..the ACL is easy to hack by changing ownership...NTFS is very weak
Even if you altered the ACL (Access Control List) to have only him on there a local admin could simply take ownership and access the file. I say for password protect EE as well.
