create your site file

There are two types of Flash files that we'll be working with. A FLA file is the working file you create in Flash and do all of your design and development in. FLA files are opened only with Flash. At the other end of the process, a SWF file is the file you export from Flash and post on the Web. The SWF file is your Flash movie and can be opened by browsers, the Flash Player, and some other applications.
