I ran a deep scan last night and recovered the files, (about 800gb total) and the majority of them came up with total gibberish as the filenames. Is there any way to determine what these files might be? They range in size from about 200mb to 4 gigabytes. I've attached a snapshot of what I'm looking at. Several other files like any video or images were recovered with the usual [numberhere].avi/jpg/exe etc. But I cant seem to figure out what happened with these other gibberish ones.
