BitComet is a torrent downloading program. Torrents are special files that allow the downloader to receive parts of the selected file from an unlimited number of sources at the same time. If your status light on the download screen is yellow, you must fix your listening port and port forwarding options to make it turn green. A green light means that your BitComet is optimised to achieve maximum download velocity.
