I decompiled a swf movie to source files, got three folders:
Edited one .as file that needed to be edited inside the action folder.
Now I need to make a swf back again with the edited file integrated.
How do I make a swf movie with the source files, frame, action and misc tags?
You'll probably have to refer to the decompiler's user manual for that - I would think a good decompiler would provide an fla file with whatever supporting elements are needed to make it work.
