Is it possible to download all pdf files from the site?

Question

Automation

Good afternoon, I really hope for help!
The bottom line: there is a site address that has several pdf documents (no titles, only *.pdf). They are available to all users (without authorization).
You need to download them, because. there are a lot of them, and it will take a very long time to climb the site with "handles".
I am familiar with scripts, but I understand that "if I were a pest", I could gobble up a bunch of traffic by putting the file download on a cycle. In general, can I do this (how) and what could be the problems if there are several such sites?

Answer 1

If the site is well indexed in Yandex, you can try "Advanced Search" on the site among pdf documents - https://yandex.ru/search/?text=&lr=5&site=site.ru&...
If you're lucky, you'll get links to all files .
More precisely, you can say when you see the site, perhaps on it pdf are in the same directory with an open index.
