Advice about working on Open Source files

Sorry if this post is in the wrong forum.

I’m trying to learn more about flash, and have found a couple of useful sites.

However, I’m having trouble working out how to use their source files, and wondered if anyone here might be able to help please.

Any advice / help much appreciated.
