Here's the situation. I have about 30,000 zip files in a folder. Many are duplicates. I want to be able to eliminate the duplicates, and have as few zips as possible without losing any roms.

Example:
a.zip has 0.bin, 1.bin, 2.bin, 3.bin
b.zip has exactly the same, same crc's
c.zip has 0.bin only (same crc as above)
d.zip has 5.bin (different crc from anything above)

I need c.zip to get deleted. I need one of a.zip and b.zip to be deleted, the other kept. d.zip must not be touched as it has roms for a different game.

There is no dat file, and no such thing as split-merged or whatever.

Can cmp do this? If not, what can?
