    Files backed up to an external harddrive that end up with the file extension "last"...


    Backed up files on PC running Windows 10 to a WD My Passport Ultra external hard drive. But the files all have a file extension "last" attached to them making them unreadable. Is this a Windows issue/fix, or is it possibly caused by the software associated with the external drive. Am a novice PC user so any explanation/answer/fix provided would be most helpful if dumbdowned. THX for any help you can provide!

    :)

    File History of files on external USB harddisk drive

    Hi,

    I have a external harddisk connected to my pc using USB. This drive contains personal files which I want to add to file history. I simply want that everytime I connect my external harddrive to my pc, that file history backs up the files on it to a location
    on the network. How do I do that?

    * I have file history working for files on an internal harddrive

    * I did add my external harddrive to the Documents library

    * I tried adding the folder on the external harddrive using the "Add a folder" using the windows 10 settings. But the folder seems to dissappear from the list after a while.

    Another detail: the disk is encrypted using DiskCryptor. Everytime I connect the drive windows says it has to be formatted. When I mount the drive by providing the key to DiskCryptor the drive becomes a valid one.

    File back up to bitlockered external drive

    Thanks John.

    By trial and error the solution is,

    • Set the file back up to the desired external USB drive, Back up using file history.
    • Run backup to completion.
    • Dismount, (Remove) the drive used.
    • Remount (Plug in) the drive used for the file back up (Steps 1&2) and encrypt using Bitlocker.
    Note you can only encrypt drives using some versions of Windows (Pro for eg not Home)

    • Once the external drive has been encrypted dismount.
    • Remount the drive, go to the file back up option, Open, Settings, Backup,
      Back up using file history      .
    • The drive should now still be visible and has been encrypted.
    • Accessing the drive will be dependant on how it was set up in Bitlocker,
      Open with this PC, password, pin code       etc.
    • Repeat file back up as in the first two steps.

    Hope this helps someone else.
