BitLocker to Go – Portable Encryption Utility for Windows 7
Microsoft introduced a concept of encryption of the entire disk with the BitLocker utility in Windows Vista. It was designed to protect customer information by encrypting machines in order to guarantee that the data was safe especially in scenarios involving stolen computers.
Later on, this concept was further extended to encrypt data on the portable drives like USB and Flash drives with the introduction of BitLocker on Go utility in Windows 7.
However, the USB and other portable drives encrypted with BitLocker to Go cannot be accessed directly in Windows Vista or Windows XP.
How to Open BitLocker To Go Encrypted Files in Vista and XP
Microsoft has released a special utility with the name BitLocker To Go Reader (bitlockertogo.exe), which is a program that works on computers running Windows Vista or Windows XP, allowing you to open and view the content of removable drives that have been protected (or encrypted) with BitLocker Drive Encryption in Windows 7. BitLocker To Go Reader allows people running Windows 7 to share their BitLocker-protected data on removable drives, such as USB flash drives or external hard drives, with anyone running Windows 7, Windows Vista, or Windows XP.Windows XP.
To open files on an encrypted drive, you need to unlock the drive using BitLocker To Go Reader and then copy the files to your computer. Once you copy the files from the encrypted drive, they will no longer be protected by BitLocker in the new location, even though they’ll still be protected on the encrypted drive.
Note: BitLocker To Go Reader works only on drives that have been encrypted using a password. If your drive is not encrypted with a password, you won’t be able to use the BitLocker To Go Reader.
