I'm interested in the full list of all possible abilities Drupal-specific Twig has to work with files, i.e. reading, writing, copying, renaming etc. Including all the abilities Twig itself has regardless of CMS. So please don't remove the tag Twig
.
Yet I just know about loading template partials like
{% include '@themename/header.html.twig' %}
It's an example of reading a file by its filesystem path
Can Drupal-specific Twig or Twig itself also rename a file? Or copy with renaming? And so on
