I'm not talking about making a zip file with all the flyers. That would be pointless. png already compresses for size savings and it's not like the snaps folder to worry about F12 clunking it up. I'm talking about scanning them unzipped and ending with them unzipped. There will be a small zip made by clrmame with just the newly dropped in ones from the new packs, then you unzip those into the folder with the others. I can't explain it any better.
