Back up file extension says "JPG_LAST File"

I have a New pc, Win 10. I already had a My Book (with working folders) and My Passport Ultra for Back ups. Starting all fresh, I set up the Passport to do a backup of the My Book and the C:drive on pc. The C: drive looks fine and i can actually see doc/photo on the back-up on passport (in the preview window). The MyBook made it’s own volume with alot of '0’s and the names of the files show up, but when i look at the actual files, i cannot view (ex: a photo) in preview window, nor can i open it…
