I've downloaded a PDF in Dupal and used the created URL. In one way or another, this document has not been registered or has been deleted. This URL (the promotion of which is widespread) leads to a page not found. I've uploaded a new document, but Drupal has slightly renamed the URL.
Can I somehow modify this URL to match the original download or redirection?
I'm not sure which version I'm using (or where to find it).
