These are large files that are purchased as zips and are not zipped by me.
Having spent money on them I'm looking at a reasonably reliable way of
archiving them, and USB sticks seem to be a good option - but they're
limited to 4GB.  Of course I could reformat them and use, say, ext3, but I
want to play safe and be able to use them in non-linux contexts.

Thanks.  I'll have a look at that, but my initial reading of the manpage is
that the splits occur at the nominated splitsize, so individual files are
almost certain to be split across different zip files.  I'm looking to make
the splits so that each new zip contains complete, unsplit, files.
