Hi, if I remember correctly, workbench looks into envarc:sys for all the different icons for disk. They have names like def_ram.info and def_trashcan.info. You could try running snoopdos and check to see what workbench is looking at for the icon. You could also cheat, go into Icon->Information, copy your Zip Icon across, select save. This does work, because I've done it myself!
