A Theme or Page for File / PDF sharing

I am looking for a simple file sharing page to share docs like PDF downloads with the public. The page should accommodate frequent loading of new versions of docs (and the deletion of older ones) for sharing. The page will be a subdomain. Preferably something like this.

http://simple-press.com/resources/

Can you recommend a WP or other 3rd party software that can do this?

Thank you.
