I'm doing some archival work with a very large (over a thousand) number of .nwc files, which are all in compressed format. I want to uncompress them all so I can use the abc2nwc utility, ultimately so that I can index them in a database. Is there a way I can do this without opening and saving each file manually?
There is no automatic solution built into the program.
You could automatic this with some kind of macro, or Windows script, but you would need experience in this sort of thing in order to save yourself any time.
