How to set a link to a Bitrix file for each article?

Question

1C-Bitrix

Having given a page with articles on the site, I encountered the problem that I have the same path to the file for all articles, but I would like each file to have its own. Well, or if it can be done in some other way, I will be glad to help. I thought to do everything on one page and draw the page through the ID in the GET request, but I did not understand how to do it.
