How to open a folder using Actionscript 3.0

Question

Hi,
I have been trying for about a day to get this to work, but nothing seems to, so i'm finally going to ask.
So far, code wise, i have this:
     open_btn.addEventListener(MouseEvent.CLICK, OpenButtonHandler);
     function OpenButtonHandler(event:MouseEvent):void
From there, what code gets flash to literally open up a folder such as My Documents? The end use of this code will be for a CD, whereby the flash .exe file will call up folders from the disc through clicking buttons. Also, please make me awear of under what situations the code may not work. At the moment, i am writting the .exe file to the desktop, and trying to open a folder on my desktop through the application.
Often times, everything i have tried so far, either causes Syntax Errors or no errors, but just doesn't work.
Thanks,
Ricky
EDIT:
Primarily in Windows, but if you know the Mac way too, that could be useful.

Answer 1

Is there no way to get buttons to open up explorer folders specified? It seems people are managing it somehow, but i can't do it. Others aprantly can do it using this code:
     on(release){
      getURL("flash",_black);
, but that's actionscript 2, not 3 which i am using. Surely actionscript 3 can do this and possibly even better seeing as it is a higher version?
I also found another bit of code that was like this:
     fscommand("exec","explorer\dirname");
,but again that didnt work. However, in another way it did because flash reported no errors when it was run, but nothing happened when the button was clicked.
The only other thing i tried was this:
     var request:URLRequest=new URLRequest("C:\\");
    navigateToURL(request);
The problem with that was that it tried to open the internet as expected unfortinatly, not windows explorer to open the folder C:\\.
Directing users to the appropiate locations on the disk wasn't really what i needed thanks for the suggestion though.
EDIT:
That last idea worked, sorry, but it opened in the default web-browser instead of using explorer, so i'm half way there. Is it possible to tell it what application to use to open the directory, so that way i can specify explorer?
