hi! I'm now starting to learn how to use adobe flash cs4. In the create file, there's a few choices of file type and I did not know which I should choose. Can I know what is the difference between action script and flash? If I wanted to create a project that include songs and pictures introducing my college, what file should I choose? Any good advice? Thanks in advance.

You should use the Flash (ActionScript 3.0) file option for a new CS4 package. However, make sure whichever you use (3.0 or 2.0) you are entering that info when googling or youtubing. You can waste a lot of time trying out a tutorial or code snippet and having it not work as intended or at all for that matter, as it may only be an attribute of the 2.0 version and not 3.0 or the other way around.
Hope this helps!
