Protect Your Files From Unauthorized Users

Other users with permission to delete a file (users with Modify or Full Control permission) can't use your encrypted files-but they can make them difficult for you to use. Any such user can rename your files, which can make them difficult to find, and can also delete your files. (Even if the user merely deletes them to the Recycle Bin and doesn't remove them altogether, the deleted files are unavailable to you because you don't have access to any other user's Recycle Bin.) Therefore, if you're concerned about protecting your files from other authorized users as well as from a thief who steals your computer, you should modify the NTFS permissions to prevent any type of modification by other users.
