Skydrive – Windows 8 – dat files with names that are too long

I moved to a new machine and installed skydrive.  I cleaned off everything that was on skydrive before I made the move.  Skydrive crashes because of some ".dat" files with names that are too long.  Then restarts, creates another Skydrive directory (under the previous one). When I figured out what was happening it was 6 levels deep. FYI there is nothing on my skydrive from what I can tell but the local machine thinks there is.  How do I kill Skydrive on the local machine, get rid of the long file names (they are Microsoft Store files which I never wanted), and start fresh?
