     * @return  void
     */

    {
        $CI =& get_instance();
        $CI->load->helper('directory'); // directory_map

        foreach (directory_map($root, TRUE as $item)
        {
            $filename = $root.'/'.$item;
            
            if (is_file($filename))
            {
                $this->add_data(
                    $zip_prefix.$item, file_get_contents($filename));
            }
            else
            {
                $this->add_dir($zip_prefix.$item);
