Short description of Folder Security 2.6 2.6: Folder Security is a software program designed to password-protect folders. It lets you prevent people from viewing, printing, or altering your confidential documents. Folders remain protected should your PC be rebooted into Windows Safe Mode or DOS. A nice feature is the ability to include a password hint. Choose something sensible and it will prompt you to remember your password, without giving it away to anybody else.
