    How can I add a new supported extension that is really just a bitmap with a different file extension?


      I have a program that writes a bitmap file with the extension .fbm. They really write it for their own use but it would be very useful if Windows (and Lightroom / Photoshop) knew it was really just a bitmap image and treated it accordingly. Anyone have any suggestions on how to do this? Corel Photo Paint at least opens it so that program must try to find out what is in the file rather than relying on the extension. Photoshop gives me an error saying that it could not fill the request because it isn't the right kind of document. Any way to tell Photoshop that it is just a bitmap since it doesn't seem to look.
