FreeOTFE, named for "on-the-fly disk encryption" creates one or more encrypted virtual disks using numerous available encryption algorithms (e.g. AES, Twofish, Serpent, and many more), and can be used to encrypt entire partitions. A separate application that doesn't require administrative rights called FreeOTFE Explorer is also available from the same site, using an Explorer-like interface (see version comparison).
64-bit users: FreeOTFE Explorer is functional, but Windows 7 64-bit users cannot use FreeOTFE as the drivers are unsigned.
Note: On startup, you will receive a message asking you to use portable mode drivers to start the virtual disk drivers (you need administrator rights to do this, otherwise the menu item will be grayed out). When you shutdown the program, you will also be given the option to stop the virtual disk drivers.
