Actually, I wouldn't try and use longer filenames if I could...
Why not use as many characters as you can -
01234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ - and store them that way....

5.3 format (assuming all the extensions have the same 3 letters) gives
you 60,466,176 combinations - 60 million ought to be plenty...
If the name of the file was to have meaning, then you could embed that
in the file itself as meta-data - after all, the files would have to
be parsed anyway, to see what the header info was.

What was the driving force in using separate files?
