I've created a button in flash and want to export and manipulate it in fireworks. I've been searching online about how to do this, but all I find is information about how to import fireworks files into flash and that is not what I need. Could you tell me if and how you can do this?
Unfortunately, your out of luck.
Fw, and other applications, for that matter, does not handle .fla/.swf files in that manner.
As your search yielded, Flash is better suited to handle native Fw files/artwork as library assets.
