An extension of arbitray length should be just as easy to parse as an
extension up to 3 characters. "Upto" implies that the extension can also
be 0, 1 or 2 characters long, so the parsing code should be sufficiently
flexible to handle 0..3 characters, and by extenstion 0..n characters is
not much more difficult (where n is the length of the filename).
With VFAT, there is no filesystem in common use that can't handle
extenstions >3 characters long.

My concern is being backward compatible with legacy systems or
compatible with special purpose realtime OS's. An application is either
portable or not, being a "little bit portable" is like being "a little
bit pregnant".
When in doubt use the Least Common Denominator.
