While these files are transparent to BitComet users, they damage the performance of other clients, because peers must devote resources and bandwidth to the padding files, with no benefit to the non-BitComet users. Starting with version 0.85 (from early 2007), BitComet added a non-standard option to its torrent maker that ensures that no two data files in a multi-file torrent occupy the same BitTorrent "piece." To accomplish this, BitComet includes in the torrent a collection of empty "padding" files which houses the remainder of each file's last "piece". BitComet is capable of downloading files over HTTP and FTP as well as bittorrent, and it includes download plugins for Firefox, Internet Explorer, and Maxthon. BitComet uses the Kademlia (mainline) DHT to operate even when the tracker is offline. torrent files, on a searchable P2P network, with other BitComet users through the torrent sharing feature, named "Torrent Share" in previous versions and renamed to "Torrent Exchange" since v.1.17. It also has a "Preview Download Mode" in which all pieces of the torrent will be, basically, downloaded sequentially thus allowing the user to play a media file while downloading (provided that the downloading speed and piece availability stay ahead of playing bitrate).īitComet also allows users to share their. When downloading, BitComet provides the option to prioritize the first and last portions of media files so that files may be previewed before they are completely downloaded. Along with the features typical of contemporary BitTorrent clients, it supports UPnP gateway configuration, bandwidth scheduling, Webseeding, selecting only certain files for download inside a torrent package, NAT traversal (removed in v.1.03), Peer Exchange (in older versions, using a proprietary protocol and starting with v.1.19 also by using the Extension Protocol, implementing a PEX mechanism compatible with μTorrent / Mainline PEX), Initial-Seeding (Super-Seeding) and support for Magnet Links. To complete a particular download, it can draw parts of files from many sources across different P2P and client–server protocols.īitComet's main features include an embedded Internet Explorer window to let users search for torrents. The BitComet program is a multi-threaded multi-protocol hybrid download manager and BitTorrent peer-to-peer (P2P) file-sharing application.
