Abstract:

Many Websites that use Flash could be optimized to load much more quickly than they currently do. By breaking up one large .swf into multiple smaller .swf files, you can decrease the time it takes your site to load, while at the same time making the site easier to manage. This article will look at how to break your Website into multiple .swf files, and discuss why it's a good idea.
