How to use the full-screen-toolbars related FLA and swf files in the resource file folder?

In the resource directory, if you want to use one of the three swfs, then rename it to fullscreenbar.swf, for example, if you want to use fullscreenbar_all.swf as the final full screen toolbar, just change the name from fullscreenbar_all.swf to fullscreenbar.swf. By default, fullscreenbar.swf is the renamed file of fullscreenbar_all.swf.
