Help to scrape pdf file

it's a platform to receive pdf files from members, and I'm one of the members & i can upload files also, I've my files URLs, any one can download my files even if it's not a member it's free and available for download for all once you get the URL ,
the point here that i want to Scrape to know every pdf files that all members uploaded at the same website, cause it's not available to know other members URLs , is it possible ?

the form of URLs are all fixed like :

page.website.com/upload/getfile/idd_xxxxx-xxxx-xxxx:filename.pdf
