Action Script Viewer (ASV) is a SWF (Flash) decompiler, a Win32 application which mainly
* lets you see the actionscripts in SWF (Flash movie) files,
* lets you extract resources (bitmaps, sounds, videos, fonts etc., also outlines of vector symbols as actionscript or SVG or a JSFL Tool) from SWF files,
* lets you browse the internals of SWF files while providing infomation about frames, instance names, symbols, movie clips etc. and a timeline view with context sensitive preview,
* helps you reconstruct the FLA file for a SWF by exporting SWF resources and a JSFL command.
ASV has many features which are listed on this page, below. You can get a feel of ASV by downloading ASV 3.00 Demo (very dated, still better than nothing). You can read more about what ASV can do for you by downloading the ASV 5 help file. See our Reviews section to learn what industry experts think about ASV.
ASV is a viewer, it does not have editing capability. (Apart from simple editing of movie properties, SWF metadata, adding/modifying the ScriptLimits and FileAttributes Tags and editing certain actionscript constants). ASV is an advanced decompiler, a professional tool for the serious developer.
