WinMagic - SecureDoc Container Encryption
Container encryption offers users the ability to create what's called a "container" which is simply a pre-defined amount of space on a drive or device that holds sensitive data, e.g. 500 MB. Users can then drag and drop files into the container to have them automatically encrypted. Encrypted data can easily be shared based on "group" key sharing, e.g. sharing files locally as well as on network shares. http://winmagic.secutel.co.uk
