Folder Lock is a fast file-security program that can password-protect, lock, hide and encrypt any number of files, folders, drives, pictures and documents in seconds. Protected files are hidden, undeletable, inaccessible and highly secure. Files can also be protected on USB Flash Drives, Memory Sticks, CD-RW, floppies and notebooks. Protection works even if files are taken from one PC to another on a removable disk, without the need to install any software.
