Folder Guard® is a powerful computer security software that you can
use to control access to files, folders, and other Windows resources,
such as Control Panel, Start Menu, and so on. You can use Folder Guard
to lock your personal files and folders with passwords, to stop other 
sers from peeking into your records. You can even completely hide
your private folders from virtually all applications, and such folders
would remain invisible until you enter a valid password. 
You can also protect sensitive system files from modification or destruction, disable
access to the removable drives, restrict access to Control Panel, and more.
