From IPC Solutions:
I_Folder_Locker is folder locking software that can password protect folders, encrypt or lock files, and protect USB Drives. The program supports all flavors of Windows such as Windows 7, Vista, XP, and 2000 including their 64-bit variants. Folder Lock creates protected storages called 'Lockers'. You can keep as many of your private files & folders in Locker and password protect it with a single click. Lockers are fully protected with latest technologies so that no one can access, delete, rename, cut, and copy. All standard as well as advanced operations are disabled on locked storages. So no one can access your protected files and folders. It uses the windows methods to lock your folder so even after you remove this software no one can open that folder until or unless you unlock it with I_Folder_Locker by entering a valid password.
