I'm sure other applications can do that too, but Bibble (since bought by Corel and named Aftershot or something) allows for several sets of settings to exist as "versions" of a RAW file, so it doesn't actually create "physical files" (the cropped/edited etc. JPEG/PNG version, that is) until it's time for the batch to output them how and where you want them, which means you can always delete and recreate the output files at will.
