CPM and the MSDOS world standard never heard of 4 character types. Earlier standards, AOS, UNIX, VMS, just used everything after the last dot in the file name.
OS 9 and its four byte type codes were officially buried by Steve a few years ago and Tim is obviously from the next world (pun intended).
Some questions are:
Are the new file types case sensitive? What if one uses case sensitive HFS+?
Is .jpg made equal to .jpeg by the finder or elsewhere in the OS?
What characters are allowed in file types? Certainly not a dot. What else? A null?, A space?, An asterisk? FFFE in UTF-8?
How is the file type officially determined if there are two or more dots? fubar.tar.gz for instance?
Under what conditions does OX neXt guess at a file type? .command seems to be assumed for anything with no dots and the execute bit set, but then X11 gets into the act too.
Files originating on older Macs still have setfile -t 'xxxx' type codes and they can also have extensions. Which code prevails under what conditions? Are droplets and finder double clicks treated the same?
Somewhere there needs to be a Bible (case sensitive) with Truth. Classic was simple.
