You have the recovered files but were they recovered by a 3rd party tool? This is what I was pointing out as to why you would end up seeing everything renamed. That will make it a real pain trying to sort everything out!
Unfortunately with the OS drive already wiped you now wouldn't be able to use other alternative methods that would simplify things. If they are still separate folders containing files however and not compressed as an archive the hassle would be sorting out which ones to see transferred back to the other machine.
Recovery programs tend to use their own naming system when recovering data. That would explain the renaming and what you have been leaving out. We will need a little more on how you went about recoverying from the drive.
