Screensaver ripping problem.

Hey. I'm having trouble ripping graphics from a rare 1994 PC screensaver I found off the internet. For some reason, I can't access them (except for system icons on Disk 1.) Any help on extracting the others? (I'm deeply sorry for all these help topics.) (Also, the attachments are separated like this in .zips because putting them together goes beyond the file size required, and the .dsk file types were invalid.)
