I usually use this technique to track the changes of differents files on large projects.

In the FLA files I add in the source code (usually on the first frame) a list of strings begining with "FlashVersionResource" followed by "#" a key name, the equal sign and the value.

The key name can be one of the following :

• Version
• Author
• Product
• or anything you like.

example:

"FlashVersionResource#Version=1.0.0.3";
"FlashVersionResource#Author=Alexis ISAAC";
"FlashVersionResource#Product=test";

To display those informations, I open the property dialog in any explorer window on a swf file. It shows all the resource string included in the swf. You can download and install the Explorer extension here :
