How do you decompile a swf file [closed]

I am the maintainer of a site that has allegedly 'lost' the source code to a flash swf file. How do I decompile this source?

Are there any programs online or offline that I could use?

Can you still open SWF files?

To open an SWF file, you can use VLC Player or the hidden Flash player from Adobe that developers often use. You can also convert and edit them.

How do I open a .swf file with contents?

open the file with Adobe Flash CS6 Professional. Then you can convert it into a . FLA and view and edit it's content. SWF files are made with this program so it should be able to open and edit the easily.

Is swf file editable?

swf files cannot be edited directly. Convert the swf file into the source file. Source file basically decompiles the swf files and break it into the text,images or other things that you have used to make the swf file.

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.
