Copying File(s) from Directory to Another

Is there a way to copy a file/doc/image from the system.ResourceDirectory (or any directory) and copy it to one of the other writable system directories?

The only way I know how is to download from an external source:

network.download(  
 "http://developer.anscamobile.com/demo/hello.png",  
 "GET",  
 networkListener,  
 "helloCopy.png",  
 system.TemporaryDirectory )  

It’s a very random question to ask, I know. [import]uid: 154122 topic_id: 28663 reply_id: 328663[/import]
