I am dealing with a Flash file which has been created by a third party. It has a lot of folders and files in the library and I can\'t seem to find any ActionScript anywhere.
I would export to swf then open it with a reverse engineer tool (like Sothink SWF Decompiler) and look through all the scripts/actions. The action name will tell you where to find it if you still need that (you'll see the decompiled code).
