FLA, SWF, ActionScript 3.0, Flash 11.4
Was removed as you do not need to decompile the SWF files, you only need to Open the swf in Sothink Decompiler and edit inside the application. Doing so makes the swf file still usable, if you decompile, it will not work properly.
Sorry for not catching the link still here sooner. I've too many posts to catch them all.
Use Sothink to examine the contents of the files and edit pictures Inside the application.
Another good application for viewing the action script to see how it is fully working is: JPEXS Free Flash Decompiler.
No recompiling is not going to be successful, but you can definitely see the scripts and how to work with them by opening the swf files in one of these apps.
Added this post 1 week after the fact, due to getting a "Like" on a post with a link that I forgot to remove.
Techniques are mentioned here in this post for what you can / can not do.
