How do you decompile a swf file [closed]

Solution 1:

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

Solution 2:

erlswf is an opensource project written in erlang for decompiling .swf files.
