FLA2SWF

Automated publishing of FLA files has been possible in Flash since at least Flash 8 using JSFL so why use a tool FLA2SWF?
Flash doesnt provide this functionality out-of-the-box, so youll have to find and install an extension that works with the version of Flash youre using. FLA2SWF works with Flash 8, Flash CS3, Flash CS4 as well as older versions of Flash that dont have JSFL support. Adding FLA2SWF to your existing build process is quick and easy.
Before you start drooling and dreaming about recovering the FLA source from SWF files, we didn’t reverse engineer the FLA format and we don’t know of any undocumented APIs in Flash. We did this the hard way. The FLA2SWF application uses Flash to open the FLA file and publish the SWF, it just automates the process so you don’t have to do it yourself.
usage:
fla2swf.exe filespec
example:
fla2swf.exe c:\project1\flas\first.fla
FLA2SWF uses Flash to open the specified FLA file, tells Flash to publish the FLA file and then waits for the publish operation to finish. If there are errors in the output window, these are extracted and written to the report file.
NOTE:
No installer is required, FLA2SWF is completely standalone and was designed to run on all current versions of the Windows desktop operating systems and works with all versions of Flash from Flash MX (6) to Flash CS4 (10).
