Code

function template_preprocess_file(&$variables) {
  $view_mode = $variables['view_mode'] = $variables['elements']['#view_mode'];
  $variables['file'] = $variables['elements']['#file'];

  /** @var FileInterface $file */
  $file = $variables['file'];
  $variables['id'] = $file
    ->id();
  $variables['date'] = \Drupal::service('date.formatter')
    ->format($file
    ->getCreatedTime());
  $username = array(
    '#theme' => 'username',
    '#account' => $file
      ->getOwner(),
    '#link_options' => array(
      'attributes' => array(
        'rel' => 'author',
      ),
    ),
  );
  $variables['name'] = $username;
  $variables['file_url'] = $file
    ->toUrl('canonical')
    ->toString();
  $variables['label'] = $file
    ->label();
  $variables['page'] = $view_mode == 'full' && $file
    ->isPage();

  // Hide the file name from being displayed until we can figure out a better
  // way to control this. We cannot simply not output the title since
  // contextual links require $title_suffix to be output in the template.
  // @see http://drupal.org/node/1245266
  if (!$variables['page']) {
    $variables['title_attributes_array']['class'][] = 'element-invisible';
  }

  // Helpful $content variable for templates.
  $variables += array(
    'content' => array(),
  );
  foreach (\Drupal\Core\Render\Element::children($variables['elements']) as $key) {
    $variables['content'][$key] = $variables['elements'][$key];
  }

  // Attach the file object to the content element.
  $variables['content']['file']['#file'] = $file;
}
