    How do I use EFS in bitlocker?


    Can I encrypt a single file that I have on a flash drive without encrypting the entire drive? How? I have W7 ultimate with bitlocker. Here is a tutorial for doing (EFS) Encrypting File System.

    Encrypt or Decrypt a Folder or File - Vista Forums

    It says to click the file I want to decrypt and click properties/general and I will see advanced option. The problem is when I do this I see no advance option. On my PC- under control pannel/ system security/bitlocker drive encryption, bit locker is currently turned off on all my drives. Do I need to enable it on my drive/drives? I was hesitant to do this because when I tried enabling this for my flash drive bitlocker drive encription opened and I feared this would encrypt the entire drive.

    Okay, I found this:
    Can I use EFS with BitLocker?
    "Yes, you can use Encrypting File System (EFS) to encrypt files on a BitLocker-protected drive. BitLocker helps protect the entire operating system drive against offline attacks, whereas EFS can provide additional user-based file level encryption for security separation between multiple users of the same computer. You can also use EFS in Windows 7 to encrypt files on other drives that are not encrypted by BitLocker. The root secrets of EFS are stored by default on the operating system drive; therefore, if BitLocker is enabled for the operating system drive, data that is encrypted by EFS on other drives is also indirectly protected by BitLocker".

    Does this mean in order to decrypt a single file on a flash drive I have to enable bitlocker on my OS drive? Is there an easier way for me to just encrypt a single file on my thumb drive?

I can't see how, in the case of having a laptop stolen, bitlocker would protect my data. If the laptop has a TPM chip, the encryption is tied to the TPM chip.. If the laptop is stolen, then the thief has access to the data on it because it would enable windows to load.. So, what is the point?...
