Flash Optimizer - description from Softdepia.com:
Flash Optimizer is a handy software solution for web-masters, web-designers,
Flash professionals and everyone who has ever come in touch with Macromedia Flash technology.
It manages to reduce your SWF files size up to 60-70% thanks to amazing algorithms of vectors,
shapes, morphing, Z-buffer, fonts and other optimizations.
Unlike any other similar software Flash Optimizer manages to optimize not only a separate part
of your Flash movie, but the whole SWF, including curves, zero-objects, ZLib optimization
and a whole lot more advanced techniques. It provides the simpliest user interface and
two types of compression configurations: simple and profound, allowing you to customize
more than 50 separate options, reaching the optimum compression with minimum quality loss.
Flash Optimizer brings a significant power into hands of Flash users,
allowing everyone to save traffic, time, interactivity and finally money!
