Xfire's File Download System and Channels
Xfire's file download system is an exclusive P2P network that distributes gaming related files (patches, demos, movies, etc) to Xfire users entirely free of charge. It's fast, convienient, and can automatically pause your downloads when you enter a game to save bandwidth. The system uses a combination of web pages (to browse and begin downloading files) and the Xfire client (to monitor your downloads and manage files you've already finished downloading.)
To find files to download, head over to Xfire's Files pages. You can access it through the tab at the top of the website or through the button at the bottom of the files tab in the client.
