I have a MyBook Essentials Edition 2.0 external backup drive. I had everything from my previous computer backed up on this drive. The old computer died.(blues screen of death after accidental power loss during shut down). It was running on Windows XP Pro. My new computer is Windows 7. I plug in my MyBook and I can see the drive on the computer but when I try and open the files it says the computer doesn't know what program to use to open them. The files are .bkf format. Can someone help me get my files on to my new computer? Many thanks!
