Same here, except it was decades ago and involved floppies,
so "flop <files>" and "unflop" were the commands I created
around split, cat, and tar. :-)

I immediately remember pax - it has multi-volume support. However,
I'm not sure if it preserves everything you're interested in. Of

rid of split. If you need compression, pax supports that, too.
