About Flash

Flash is an authoring tool that allows you to create anything from a simple animation to a complex interactive web application, such as an online store. You can make your Flash applications media rich by adding pictures, sound, and video. Flash includes many features that make it powerful but easy to use, such as drag-and-drop user interface components, built-in behaviors that add ActionScript to your document, and special effects that you can add to objects.

When you author in Flash you work in a Flash document, a file that, when saved, has the file extension .fla. When you are ready to deploy your Flash content, you publish it, creating a file with the extension .swf. The Flash Player, described in the next section, runs the SWF file.
