You Cannot Configure
NTFS Permissions to Hide Files or Folders from
Unauthorized Users
Microsoft Knowledge Base Article: 303758 - Novell
NetWare administrators can configure permissions
so that users cannot see files or folders in the
file system for which the users do not have Read
access by removing the File Scan (F) permission.
This type of access control is not supported by
the NTFS file system. Therefore, users can view
the contents of any folder for which the user
has the List permission. Removing the List permission
for the folder prevents the user from gaining
access to any file in the folder.
