Folder Lock

Folder Lock™ is a fast file encryption software that can also password protect folders, lock files, protect USB Drives and lock CD/DVDs. Works perfectly on all flavors of Windows 7, Vista, XP and 2000 (supports 64-bit OS as well).
Folder Lock creates encrypted storages called 'Lockers'. You can keep as many of your private files & folders in your Locker and password protect it with a single click. You can transfer, secure and backup these Lockers. Lockers are portable, you can keep them in USB Drives, CD/DVD, & notebooks or transfer them via email or upload. These Lockers are undeletable on the computer where Folder Lock is installed.
You can create as many Lockers as you want. Different users can create different Lockers with different passwords as well. With Folder Lock, you can choose either to encrypt using 256-bit AES on-the-fly encryption or lock files, folders and drives anywhere on your computer. Each Locker can contain your encrypted files as well as your personal list of locked items.
Furthermore, Folder Lock's options like hack monitoring, stealth mode, data shredding, history cleaning, auto protection, portable USB autoplay feature & virtual keyboard can enhance file locking and encryption beyond anything ever achieved. In addition, a locker's delete, move and rename are password protected to prevent data loss.
