Sharing Remote Files

Hi, I have a large number of documents and visio designs (100+ in quantity and 5GB+) I wish to be made available for download from my WP site. The documents reside on a local file server, and I want to avoid uploading them onto the server hosting the WP site, due to disk space, backup times, version control, etc..Is there an efficient way\plugin I can use to share these files via my WP site, without uploading them to the WP server?
