One program per function per extension. So for a given extension you
might have one program to print it, one to edit it, one to play the
music embedded within it (to make something up). One of these
functions will be the default function, and that one will be invoked
when a file of the given type is double-clicked in Windows Explorer.

I suspect that, in practice, the same program is used for the
different functions but with different command-line switches, or DDE
commands, or some way of telling the program what to do.
