private var fileStream:FileStream;

private function downloadFile():void
{
    var file:File=File.desktopDirectory.resolvePath('fileName');
    fileStream=new FileStream();
    fileStream.open(file, FileMode.WRITE);

    var urlLoader:URLLoader=new URLLoader();
    urlLoader.addEventListener(Event.COMPLETE, onDownloadedComplete);
    urlLoader.dataFormat=URLLoaderDataFormat.BINARY;
    urlLoader.load(new URLRequest('downloadLink'));
}

private function onDownloadComplete(evt:Event):void
{
     fileStream.writeBytes((evt.target).data);
     fileStream.close();
