ScriptLogic Cloak enables you to hide the folders and files on NTFS partitions from users who don't have the necessary permissions to access them. This utility works by installing its own driver. The ScriptLogic Cloak File System Driver evaluates the access control lists (ACLs) of the folders or files each user attempts to access, as well as the user's group memberships. If the user doesn't have permissions for a file or folder, the File System Driver prevents Windows Server 2003 from displaying the file or folder.
