| Ext. | Explanation |
|---|---|
| .swf | .swf files are completed, compiled and published files that cannot be edited with Adobe Flash. However, many '.swf decompilers' do exist. Attempting to import .swf files using Flash allows it to retrieve some assets from the .swf, but not all. |
| .fla | .fla files contain source material for the Flash application. Flash authoring software can edit FLA files and compile them into .swf files. |
| .as | .as files contain ActionScript source code in simple source files. FLA files can also contain Actionscript code directly, but separate external .as files often emerge for structural reasons, or to expose the code to versioning applications. They sometimes use the extension .actionscript |
| .swd | .swd files are temporary debugging files used during Flash development. Once finished developing a Flash project these files are not needed and can be removed. |
| .asc | .asc files contain Server-Side ActionScript, which is used to develop efficient and flexible client-server Macromedia Flash Communication Server MX applications. |
| .flv | .flv files are Flash video files, as created by Adobe Flash, ffmpeg, Sorenson Squeeze, or On2 Flix. It's container format that uses (mostly) h.263 for video and MP3 for audio. |
| .swc | .swc files are used for distributing components; they contain a compiled clip, the component's ActionScript class file, and other files that describe the component. |
| .jsfl | .jsfl files are used to add functionality in the Flash Authoring environment; they contain Javascript code and access the Flash Javascript API. |
| .swt | .swt files are 'templatized' forms of .swf files, used by Macromedia Generator. |
| .flp | .flp files are XML files used to reference all the document files contained in a Flash Project. Flash Projects allow the user to group multiple, related files together to assist in Flash project organization, compilation and build. |
| .spl | .spl files are FutureSplash documents. |
| .aso | .aso files are cache files used during Flash development, containing compiled ActionScript byte code. An ASO file is recreated when a change in its corresponding class files is detected. Occasionally the Flash IDE does not recognize that a recompile is necessary, and these cache files must be deleted manually. They are located in %USERPROFILE%\Local Settings\Application Data\Macromedia\Flash8\en\Configuration\Classes\aso on Win32 / Flash8. |
| .avi | AVI file is a video file, standing for Audio Video Interleave. Flash includes several compression codecs, including some from Radius. |
| .gif | A GIF image; either a single static frame or multi-frame animation. |
| .png | A PortableNetworkGraphic image. |
