Yes, they could also be identified (and some more interesting info gleaned)
from the first couple of bytes, the executable header. Don't remember the
definition of the top of my head, but I know hex 4AFB appears in it :-)

Resident extensions cannot be recognized as they are just pieces of code,
they are called after they are loaded (LRESPR), but don't have any defined
headers etc.

There is also file type 2 (or was it -1?) for linker files. Pity the file
type isn't used more often.
