ASV is a SWF decompiler and resource extractor, a 32-bit Windows utility application, that lets you view actionscripts embedded in SWF (Flash movie) files, extract resources and browse the internals of SWF files. ASV is an advanced SWF decompiler for serious Flash developers

ASV supports actionscripts in SWF files, version 7 and below, compiled by Macromedia Flash / Flash MX / Flash MX (professional) 2004. These scripts are decompiled and converted to text format, which you can then view on screen, save as a file, or copy to Clipboard. Pasting text directly into Flash script editor is possible, and the output syntax of ASV is very close to the original.

ASV displays lists of frame labels, instance names, library symbols; provides a timeline view with context sensitive preview with many options. ASV can extract most of the resources from SWF files and displays all the necessary information to help you reconstruct a FLA file you have lost. ASV even tries to help reconstructing a FLA file by generating a JSFL command file for Flash MX 2004 to rebuild the FLA
