I just recovered data on a hard drive whose table got trashed and used photrec to recover the data. It, however, recovers the title of the files into hex, save the "extension" ( these are from my son's external drive which was a fat32 on his Windows system and contain his music collection, so the files are now named something like f548397.mp4). I've not been able to come across a utility to do this. I looked at convmv, but that doesn't seem to do it. There may be, I hope, some simple way to do this. Any help would be greatly appreciated.
