Decrypt bitlocker files using key
I saved a few files from an encrypted laptop to an external drive. I am now trying to access the files but am getting an access denied error. I have the unlock key but am not sure how to proceed.
The laptop has been decrypted and the drive was formatted so this is the only copy of the files that I have.
Any help would be greatly appreciated.

As I told you in your other thread: bitlocker CANNOT encrypt single files. So it is impossible that those files you are talking about are encrypted using bitlocker.
The access denial must have another reasonm.
Please explain.

I understant that bitlocker does not encrypt single files. We used it to encryt the entire drive. I created some files on the laptop and moved them to an external hard drive. When I look at the files in the external drive they are encrypted and I get an access denied error when trying to open them.

Who/what tells you they are encrypted? Access Denials have nothing to do with encryption.

The file names are green

Could it be that I transferred the files from the encrypted drive to another encrypted drive?
Green means efs encrypted, not bitlocker.

I transfered the file to an encrypted hard drive. Could that be the issue?

Time for feedback :)
Agreed with McKnife, BL encrypts the whole drive, it's a FileSystem encryption and the data is either visiable or not, locked or unlocked. EFS is a file/folder level encryption and they are typically visible at any time. I recommend AEFSDR from elcomsoft or PassWare's recovery suite. If you didn't save the certificates from that drive, or an "undelete" utility can't locate them, you will not recover the files. BL can also encrypt USB drives, and again it's the whole drive or partition that is encrypted not just a few files.

Efs recovery, as outlined in https:#a39219804 would normally solve it, otherwise, cracking, as suggested in https:#a39310222 as last option.
Forgot to object.
Agreed and object as well.
