Not exactly. The file type lives in the file header, not the resource
fork. But it is a concept peculiar to the mac which apple appears to be
moving away from.

VAX/VMS has always had file extensions and always used them to mark file
types. It was (is) not possible to have a file without a "." in it. As I
recall you could have about 30 characters before the "." and about 30
after it (or you could after ~1982 or so).

Well, not really. Posix has a ~256 character in filename limit. VMS
still has the limits above (~30 character extensions).
