The filename of a just loaded file via FileReference is not available

Question

To load 3 files locally into the Flash Player, one might using something like this manage the sequence after the user has chosen the files...

 private function uploadList(evt:Event):void{

  var arr:Array = fileReferenceList.fileList;

  for each(var item:FileReference in arr){
   item.addEventListener(Event.COMPLETE, onFileLoadComplete);
   item.load();
  }

 }

// Step 2 - go ahead and load the file and wait for step 3...this will be called three times in this use-case.

 private function onFileLoadComplete(e:Event):void {

     var loader:Loader = new Loader();

     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDataLoadComplete);
     loader.loadBytes(FileReference(e.target).data);
 }

// Step 3 - Flash Player has loaded the file and is ready for processing... // this example is an image being stuffed into a BitmapData object...

private function onDataLoadComplete(e:Event):void {
  var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData;
  var loader:Loader = Loader(e.target.loader);

...

}

// Step 4 - Where is the filename and file byte size located for each file passing through Step 3?

I've not been able to locate this data in existing objects.

My own resolution....

I stuff the info into a simple dictionary and retrieve it later.

Perhaps there are other solutions out there?

private function onFileLoadComplete(e:Event):void {

  if(FileReference(e.target).data.length == 0){
   return;
  }   

     var loader:Loader = new Loader();
  filenameDict[loader] = String(FileReference(e.target).name);

     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDataLoadComplete);
     loader.loadBytes(FileReference(e.target).data);
 }


 private function onDataLoadComplete(e:Event):void {
  var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData;

  var loader:Loader = Loader(e.target.loader);
  var file:String = filenameDict[loader];
  delete filenameDict[loader];

You can do it with arrays but as you can see from the code, Dictionary is the easier way.

var files:Array = [];
var loaders:Array = [];
private function onFileLoadComplete(e:Event):void 
{
  var loader:Loader = new Loader();
  files.push(e.target);
  loaders.push(loader);
  loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onDataLoadComplete);
  loader.loadBytes(FileReference(e.target).data);
}
private function onDataLoadComplete(e:Event):void
{
  var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData;
  var loader:Loader = Loader(e.target.loader);
  var index:Number = loaders.indexOf(loader);
  var file:String = FileReference(files[index]).name;
  /*
   * Clear the arrays to get rid of unwanted references that might 
   * prevent them from being garbage collected.
   * */
  files.splice(index);
  loaders.splice(index);
}

I was oblivious to FP10's FileReference when I made the first version of this post.
