Slice'n'Splice
Picture a scenario... You've spent a substantial part of the day down-loading the latest, fastest, bestest shoot-em-up game demo. And of course, you're not stupid, so you did this at work using the fast company internet connection. But you wouldn't dare actually play the thing at work, far too... It slices huge files into floppy (or any other) size chunks, and then splices them back together again. ... You realise, with mounting dismay, that you'll have to create the whole zip set again. ... Each chunk can be copied to a floppy independently of the rest.
