I have a topic in my Discourse forum that contains an upload link.
This is an executable file that I would like to update with a newer version, without changing the URL, so that any existing external links remain functional.
Hi Uwe! No, it’s not possible to upload files to Discourse and keep their original file name. You’ll want to upload it elsewhere and link to it from your forum.
Put a permalink (managed at /admin/config/permalinks) to the upload on the topic. When you update the file, also update the permalink and you can get the behavior you need.
