Folder Guard

Folder Guard is a Windows security program which you can use to restrict access to files, folders, and other computer resources. If you share your computer with your business colleagues, family, or roommates, you can use Folder Guard to stop other users from opening your personal files, or even completely hide your documents until a valid password is entered. You can protect sensitive system files from modification or destruction, disable access to the floppy, CD-ROM, and other removable drives, restrict access to Control Panel, Start Menu, applications, and more.
