Hey, thanks a lot! I finally figured it out with help from the stackoverflow thread that @heckflosse linked to. It probably took me half an hour, because I had no idea what the correct syntax was to make dcraw and the FOR command work with each other. Just for future reference, the command that worked for me is:
for %f in (*) do dcraw -w -W -T -6 %f
(That’s what I typed right into the command line, I didn’t actually make a bat file)
I’m really glad to find out that there IS a way to make dcraw see more than one file, even if it has to be slightly complicated.
