The extension (in today's OS X) and the old file type (creator was different??) is usually, up to, four (single-byte) characters.Mac OS had a 4 character field for storing file types, yes. These could be any four characters. It also had another 4 character field for storing the application associated with that file (the creator). For example, in BBEdit, the combination of TEXT/R*ch indicated that the file was a normal text file, and that it should be opened by BBEdit (R*ch) as opposed to, say, teachText (TTXT, IIRC).
None of this had anything at all to do with extensions.
