Hi. I read a couple of threads that seem similar, tried those things - no luck. This is Windows 7, Home Premium, 64 Bit, 3 Gig of memory, etc. 500 Gig - Backup drive is an external through the USB - 454 Gig., 151 G used. Backup seems to work fine - did it twice now, with same error message. Backup encountered a problem while backing up file C:\Windows\System32\config\systemprofile\Videos. Error:(The system cannot find the file specified. (0x80070002) I navigate to that spot, and sure enough, there is nothing there that says "Video". Reading the other thread, it appears that I moved the "Video" files. I tried opening various things, in Explorer - no luck in resolving it. I did, at some point, try to eliminat a duplicate reference to My Videos. May have upset the "library" stuff. I would put it back if I could figure out how. When I open "Libraries", I see Documents, Music, Pictures, Videos. I assume that one is the problem. When I click on Videos, all I have is "Public Videos". My Videos is down under Public Videos. Music gives me Public Music and My Music. Under "Pictures" I have My Pictures, Public Pictures, Videos (C:), and Prints (C:) Interesting. I never have figured out what the "Libraries" thing does exactly - usually mess around with the C drive directly. But . . . in the interests of getting rid of this message, I'll put it back, or whatever. Thanks. Really a minor issue - I love Windows 7 compared to all of those other things you folks have generated in the past! Still not caught up to Mac, but gaining!
