Small Web Format (SWF) files are Flash animation files that can be played in any browser with an Adobe Flash plug-in. When you are creating Flash animation, you will want to view the file the same way the end user will view it: through a browser. To test an SWF file, you can open it in your browser, a process that takes a few moments.
Save your SWF file to your desktop.
Launch your Web browser.
