Flash Decompiler Trillix (former SWF to FLA Converter) converts Adobe Flash SWF files back into FLA format which can easily be edited in native Flash environment. Every group of objects such as morphs, shapes, texts, fonts, motions, sounds, ActionScripts, etc. could be placed in separate FLA library groups, which makes using and working with the resulting FLA file much easier.
Moreover, since Trillix version, in addition to SWF to FLA conversion, Flash Decompiler can extract all objects (images, sounds, video, shapes, text, morphs, ActionScripts, etc) used in SWF files into various file formats just in several clicks.
Additionally, you may customize FLA file workspace by enabling/disabling grids, rulers; specifying grid accuracy and so on. Every morph or shape can be placed on different layers to make sure that masks layers are working properly. Flash Decompiler Trillix is the only Mac OS tool to export the whole SWF movie in FLA format that supports Flash 10, Flash CS5 (except TLF texts and conversion to XFL format) and ActionScript 3.0.
