PenProtect enables you to protect the files your USB pen drives with 256-bit AES encryption. The program encrypts your files and also scrambles the folder and file names for additional privacy. To unlock your files, you need to run the PenProtect program (from the pen drive) and enter the proper password, which will restore your files to normal. You can choose to encrypt the entire drive or only selected files and folders. PenProtect comes as a single executable that is copied directly to your USB drive and run from there, no installation is needed.
