AS3 File Reference Manager Class using the File Reference API


 / Published in: ActionScript 3
 

Based on the following references:

I created a simple file manager class that I will be extending in the near future for an AIR App I will also be releasing. If you have more that could be added, let me know and I would be glad to make modifications. Enjoy my fellow actionscriptrs!
