Getting a size from a loaded file via a File variable type ActionScript3

Cannot get my file size! I have a variable that loads the file, and then on my fileCompleteLoad event i want to check the size of that file (.png).

// clickButton event to load the file

public function onMouseClick(e:MouseEvent):void{
    _fileRef = new File();
    _fileRef.addEventListener(Event.SELECT, onFileSelected, false, 0, true);
    _fileRef.addEventListener(Event.CANCEL, onCancel, false, 0, true);
    _fileRef.addEventListener(IOErrorEvent.IO_ERROR, onIOError, false, 0, true);
    _fileRef.addEventListener(SecurityErrorEvent.SECURITY_ERROR, 
    onSecurityError,  false, 0, true);

    _fileRef.browse([_imageFilter]);
}

// selected event

public function onFileSelected(evt:Event):void
{
    _fileRef.addEventListener(ProgressEvent.PROGRESS, onProgress, false, 0, true);
    _fileRef.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
    _fileRef.load();
}


// thats my eventComplete

 public function onComplete(evt:Event):void
{
    _msgSuccessErrorTextField.text = "File was successfully loaded.";
    _pngInputTextField.text = String(_fileRef.nativePath);
    _atfOutputTextField.text = _fileRef.nativePath.replace(".png",".atf");
    _inputNativeProcess = _fileRef.nativePath;
    _outputNativeProcess = _atfOutputTextField.text;
    _flagLoadedFile = new Boolean(true);

    var test:Bitmap = evt.target.data as Bitmap;
    if(test){
        trace(test.height);
    }

    _fileRef.removeEventListener(Event.SELECT, onFileSelected);
    _fileRef.removeEventListener(ProgressEvent.PROGRESS, onProgress);
    _fileRef.removeEventListener(Event.COMPLETE, onComplete);
    _fileRef.removeEventListener(Event.CANCEL, onCancel);

Now, in that event i want to check my file size... I ve tried many things but didnt get success... and sometimes i get null from my _fileRef.data.

Any suggestions to solve that?

thx

the Answer is -

//add that on my public function onComplete(evt:Event):void{}

var loader:Loader = new Loader();

loader.loadBytes(byteArray);

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loaderComplete);

// build another event

publicfunction loaderComplete(event:Event):void
{
var loaderInfo:LoaderInfo = LoaderInfo(event.target);

var bitmapData:BitmapData = new BitmapData(loaderInfo.width,
loaderInfo.height, false,   0xFFFFFF);

bitmapData.draw(loaderInfo.loader);
// result: bitmapData

}

now i can get the Heigh, witdh and whatever... thx!

Just to make sure, are you getting the data inside the onComplete handler? The code you show doesn't do that right now. Should be something like : 

_fileRef.addEventListener(Event.COMPLETE, onComplete, false, 0, true);

private function onComplete(e:Event):void
{
    var test:Bitmap = e.target.data as Bitmap;
    if(test)
        trace(test.height);
}
