To further add on to that, I would frequently run into programs (and sometimes games) that would span multiple floppies where almost the entire first part of the archive was just installer data. Sometimes, the actual .zip file data would start on the tail end of the first disk and then span however many disks were needed while other times the first disk was just the installer and then the .zip data was on the other disks. In either case, PKZIP and PKUNZIP would be able to read that file but only in the 2nd case would they be able to read the file without that first disk.
Things got further complicated when RARs made the scene because I remember that some of the early .RAR apps offered their own implementations of .zip support that would create multi-span .zips where the installer data was on the first disk, the .zip data was on the other disks, but the container spanned all the disks.
This meant that you could potentially have 3 different ways of dealing with the same data and there was no safe way to assume which method was used:
1. Installer on disk 1, multi-spanned .zip on disks 2-n
2. Multi-span .zip on disks 1-n
3. Multi-span .zip on disks 1-n but installer data only on disk 1
