Folders on server, how can I get Google to index the PDF?

[denvercardonations]

I have a folder lots of pdf files in a folder on my server, in order to get Google to index these PDFs, do I just set folder permissions to 755, the PDFs to 644, and and directly link to these from my website?

But, I have a queston? Can we get backlinks by PPT and PDF's sharing.
Is it helpful to rank our website?
