Mac-to-PC Utility?

[Nancy Allison]

Hi, everyone. I have many scanned jpg images on Mac-formatted zip disks. I
still have an elderly (Windows 2000) PC with a zip drive, so I need a
utility that can read the zip disks and transfer the files to the PC.
 
This is a one-time exercise, so I'd really rather not spend any money. Does
anyone know of a freeware utility (or any workaround) to do this?
 
I've googled this topic; haven't found any obvious candidates.
 
Thanks for your help.
