Repository support http://docs.moodle.org/en/Repositories is a new feature in Moodle 2.0:
* Moodle now supports integration with external repositories of content, making it really simple to bring documents and media into Moodle via an AJAX interface that looks like a standard Open dialogue in desktop applications.
* Initial plugins in 2.0 include: Alfresco, Amazon S3, Box.net, File system on Server, Flickr, Google Docs, Mahara, MERLOT, Picasa, Recent Files, Remote Moodle sites, WebDAV servers, Wikimedia, Youtube. These are simple to develop, so many more are expected.
* You can also import files from your desktop or by specifying a URL.
