Simply "publish" your file in Flash (use the file option on the menu bar, scroll down to where it says Publish Preview, and over to HTML (or else hit F12). If you like, you can cut and paste out the swf code and place into a separate HTML file. Simply look for the two object tags <OBJECT> and </OBJECT> and copy them (and everything in between them) into your other HTML page.
Watch out for any URL's you have in your file. The codes for these come between the <A HREF> and closing </A> tags. You'll need these too, if you transfer the source code.
