function delete($force = FALSE) {

  // If any module returns a value from the reference hook, the

  // return a populated array that tests as TRUE.
  if (!$force && ($references = module_invoke_all('resource', $this))) {
    return $references;
  }

  // Let other modules clean up on delete.
  module_invoke_all('resource_delete', $this);

  // Make sure the file is deleted before removing its row from the
  // database, so UIs can still find the file in the database.
  if (unlink($this->url)) {
    db_query('DELETE FROM {resource} WHERE rid = %d', $this->rid);

    // remove internally used static cache entries.
    $this

    $this
      ->reset_cache('url::' . $this->url);
    return TRUE;
