    foreach ($dir as $f) {
      if($f != "." && $f != ".." && $f != ".DS_Store") {
         if(is_dir($dirname.DIRECTORY_SEPARATOR.$f)) {
            $dname = $dirname.DIRECTORY_SEPARATOR.$f;
            readRecursive($dname);
         } else {
            $fileslist[] = $dirname.DIRECTORY_SEPARATOR.$f;
         }
      }
