Make sure to create a “BitLocker recovery key” when you turn on BitLocker for the first time. To unlock this lock, a special BitLocker recovery key must be entered. If a potential security risk is detected, BitLocker locks the operating system drive. If you encrypt the drive where the operating system is located (drive C:), BitLocker checks at startup for conditions that could pose a security risk to your computer. Authorized users will be able to access these data bypassing the security layer. If you have shared files over the network, those files will remain encrypted as long as they are stored on the encrypted drive. Files copied to another drive or computer are copied out without a password.
As long as the files are stored on the encrypted drive, they are stored in encrypted form. Every file you upload to a drive that you encrypt is automatically encrypted by BitLocker.
