FreeOTFE Explorer is a system which allows FreeOTFE volumes to be accessed not only without installing any software, but also on PCs where no administrator rights are available. This makes it ideal for use (for example) with USB flash drives, and when visiting Internet Cafés (AKA Cybercafés), where PCs are available for use, but only as a "standard" user.

FreeOTFE is a free, open source, "on-the-fly" transparent disk encryption program for PCs and PDAs. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.
