You can easily save the decompiled script to a single text file or into a folder structure. AS3 Sorcerer also shows vital Flash file information including contents of SWF header, Metadata and File Attributes tags. You can use AS3 Sorcerer to examine AS3 class scripts in a Flash file, for learning purposes or for recovering your work if the source is lost (AS1/2 scripts are not supported).
