SharedObject question (I think)

Is my code :

private var so:SharedObject = null;

   private function saveFile():void

   {

    try{

     so = SharedObject.getLocal("domain", "/");

    }

    catch (e:Error)

    {

        return;

    }

    so.data.main = _byteArray;

     var flushResult:String = so.flush( 10240 * 1024); //

     if (flushResult == SharedObjectFlushStatus.PENDING)

     {

      so.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);

     }

     else if (flushResult == SharedObjectFlushStatus.FLUSHED)

     {

     }              

   }

After running the flash player,

I saw the C: \ Users \ * \ AppData \ Roaming \ the Macromedia \ Flash Player \ # SharedObjects \ 4QUP95TY \ # the localhost file domain.sol and can get to the value of the object.

But when I turn off the flash player, the file is automatically deleted.

I use the " var flushResult:String = so.flush( 10240 * 1024)".

Why back in the flash player is turned off automatically deleted

How to deal with can be permanently stored in the local, rather than close the flash player is automatically deleted after
