You can control bytesTotal (LoaderInfo) and then close the Loader ( myLoader.close() ) if it's too heavy...

import flash.display.Loader;
import flash.display.Sprite;
import flash.events.*;
import flash.net.URLRequest;

var url:String = "Image.gif";

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler);

var request:URLRequest = new URLRequest(url);
loader.load(request);

addChild(loader);

function progressHandler(event:ProgressEvent):void
{
if (event.bytesTotal > 10000000)
{
  loader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
  loader.close();
}
}

Thanks for your support . Actually  my question is i am able to show the percentage or frames loaded wile  downloading the file.But

I need how to stop the file  loading process while clicking on another button. If the user donot want  to wait complete loading the file, he want to stop the loading.

I have also write the below code. These code just remove the ProgressEvent but not stop the Loading

ldr.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS, progressHandler);
  ldr.close()
