    Hi John,

    We suggest that you try the troubleshooting steps below:

    • Open your External Hard Drive file in File Explorer.
    • Type the name of the file you want to search on the search box and click Enter.
    The file will show up in Search Results and you will be able to move it to the correct folder.

    Let us know if you need further help.
     
  3. Cannot decrypt files on personal external drive

    I have a 4TB WD MyBook which I use as an external drive that is always connected to my desktop .

    On there, I encrypted a folder with other files in it. Whenever I tried to decrypt the folder or the files, I receive and error saying:

    An error occurred applying attributes to the file:

    E:\Files\201...\Morris.jpg

    The specified file could not be decrypted.

    Not sure how to go about this error.

    Any advise would be appreciated. Thanks!

    How to decrypt and copy over a Bit Locker encrypted folder stored on an external drive, in Windows 10

    I had used BitLocker to encrypt my Windows 10 PC, and periodically backed up my files to a folder on an external drive (that also included backups from different, non-encrypted computers in other folders).

    Last week I had to factory reset my PC because it was freezing frequently. When I tried to copy over my files from the external drive, the folder they are stored in along with all the files are encrypted and couldn't be transferred.

    When I try to open the files directly from the external drive they have a locked padlock icon and the error message says:

    • "It looks like you don't have permission to view this file. Check the permissions and try again".

    The error messages I receive when I copy over individual files from the external drive to my (reset) PC are:

    • "You'll need to provide administrator permission to copy this file", and
    • "You require permission from Everyone to make changes to this file"

    when I try to copy over entire folders, the error message I get is:

    • "Do you want to copy this folder without encryption? A problem is preventing this folder from being encrypted"

    I have the bit locker recovery key for my PC prior to factory reset. However I can't find a way to transfer my folder back from the external drive into my (now reset) PC.

    Does anyone have any suggestions?

    Thanks!
