Copy a file to user's desktop in Flash

Hello experts,

I'm re-programming in Flash the content and user interface of an old CD that uses a stand-alone exe projector file that was originally made in MacroMedia Director.

One of the functions I'm re-doing is the ability of this program and disk to paste a PowerPoint document from the CD onto the user's desktop when they click a button in one of the screens. I've tried the button on a Windows XP system and it works fine. No extra windows or anything, it simply shows up on the desktop.

Can Flash do this in AS2? (Which I'm more familiar with than AS3.) Or do I have to move up to AS3 or is it not possible to do in Flash at all?

Thanks!
