How that works is the <three ramdom hi-ascii characters> aren't necessarily
hi-ascii.

It's the bytes that represent the ProDOS filetypes.

For example, with a ShrinkIt archive...It's filetype is:
Main:     $E0
Auxtype:  $8002

So, on the HFS disk, the filetype would end up being
'p$E0$80$02'.

The HFS FST does this on the GS end and the Appleshare FST knows how
to translate what the Mac sends for filetypes.

I'm not sure how random-access text files are stored as a filetype or
binary files with an adress other than $0000.  Never have experimented
on that.
