Yep. That would be the traditional XP way of selecting by file type.
However, it's way easier being able to use wildcards, as FileMenuTools purports to being able to do.
I did find a useful solution that exists for everyone without an extra needed program, that should have been pretty obvious, but I hadn't thought of it before writing here:
-- Use Windows SEARCH, and put the wildcards, extension in there.
Sooo, Skwire, if no one has anything else to add to the discussion, maybe this one is done.
