[flexcoders] how to open a file system UNC path (windows share)

[vaster3302]

How can I open a UNC (windows share) in windows explorer from flex (flash 
builder 4)?

I tried a couple different things:

var request:URLRequest = new URLRequest("file://\\\\myserver\myfolder"); 
var loader:URLLoader = new URLLoader(); 
loader.load(request); 
which gives a stream error

and

var urlRequest:URLRequest = new URLRequest("file://\\\\myserver\myfolder");
navigateToURL(urlRequest, "_blank");
which opens a browser window with file://myserver\myfolder in the url.

I want to open a folder (and hopefully a file) as if the user navigated in to 
the share and double clicked it.

Thanks!
