Of course, the reason to support MacTypes is because you can also blindly remove the extension entirely. If you have a file that *does* have a MacType that is correct, and you specify both a MacType and extension, it will work properly in all cases. If you simply specify a dummy MacType, it won't work if the file ends up without an extension, because you didn't specify a MacType that matched.
