While NT-based versions of Windows have supported per-folder encryption functionality via the Encrypting File System (EFS) for years, Windows Vista was the first to introduce full-disk encryption in the form of BitLocker. Now, in Windows 7, Microsoft has enhanced BitLocker with the ability to protect removable storage devices, such as USB-based hard drives, flash devices, and other media. This functionality is called BitLocker To Go, and while the technology is aimed squarely at enterprises, it's quite useful for almost any Windows 7 user.
