private File getTargetFile(DropTargetEvent event) {
    // Determine the target File for the drop
    TreeItem item = tree.getItem(tree.toControl(new Point(event.x, event.y)));
    File targetFile = null;
    if (item != null) {
      // We are over a particular item in the tree, use the item's file
      targetFile = (File) item.getData(TREEITEMDATA_FILE);
    }
    return targetFile;
  }
});
