How to Test an SWF File
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.
Click "File" in the main menu bar. Scroll down and click "Open."
Browse for the SWF file you saved on your desktop. Click the "Open" button.
