Most of us who download scene releases don’t keep the original RARs, sample, NFO & SFV files after extracting the goodies inside. If you unpack and delete the RARs, there’s no way to get back to the originals without some major hacking - and even this doesn’t guarantee that the rar set will pass a proper CRC check when reseeding. But if you have the *.avi or *.mkv file, Rescene is a cool utility that lets users rebuild scene release NFO, SFV and RARs from a single extracted file back into their original scene format.
