That didn't work. I don't know if Win 7 does something different with the files, but I searched for .chk files there were a few for windows live mail and firefox, but nothing for the files I was looking for.
I downloaded Pandora Recovery, which locates deleted data, and it shoes the data has not been deleted?!, but the folder that my data is in isn't seen by windows explorer (and yes, I do have windows set to show hidden files and folders) so somehow windows erased the folder, but not the data in that folder - how do I get to my data?
(BTW - Pandora shows my data in a file called found.000, not the original folder I created, which is gone now, but from there everything else looks fine, but Pandora won't let me do anything with the files I see, because it "sees" them as NOT deleted)
