Huh, I'm trying to model what an exploit would look like here - who &
what would be vulnerable to this? Obviously you *can* create a disk
file with a non-EXE extension & whatever contents you want, but under
what circumstances is another program gonna call the load-and-execute
routine on any arbitrary filename (other than, as mentioned, app-menu
utilities or command-shell alternatives?) Or if the game is to replace
one of an application suite's own I-can't-believe-it's-not-EXEs with a
Trojan, which developers bothered to mask their secondary EXEs under a
different extension, and why...?

(I mean, yes, installers might well build a final EXE from smaller
and/or compressed/encrypted chunks, but the *resulting* file would
normally still have an EXE extension, and be invoked the usual way.)

Not saying that it doesn't make sense to check files on a better-safe-
than-sorry heuristic, just trying to figure out how you'd get to the
point of pulling that kind of trick in the first place...
