Transmission is a BitTorrent client for the Mac and Linux operating systems. It is the most popular client on Mac OS X and the default BitTorrent client on many Unix and Linux distributions, including Ubuntu, Mandriva, Fedora and OpenSuse.
Although open source and technically cross-platform in nature the developers of Transmission has not released a Windows version of the software yet.
Transmission-Qt Win is an unofficial Windows build of Transmission which features a simple interface on top of the cross-platform back-end. The interface and functions of the Windows port is identical to that found on the Mac and Linux counterpart.
Transmission is a pretty advanced BitTorrent client with powerful features, most of these already available on uTorrent and similar software with the exception of blocking bad peers with a blacklist.
Here are some of the more important features of Transmission:
- Prioritization to select which torrents, and which files inside those torrents, to download first
- Supports Magnet links
- Selective downloading
- Optionally move torrents to a different folder when they finish downloading
- Encrypted peer connections
- Torrent file creation
- A built-in web server so that users can control Transmission remotely via the web (using RPC or WebUI)
- Automatic port mapping (using UPnP/NAT-PMP)
- Fast Resume — with peer caching
- Blocklists for bad peers, periodically updated with the same bluetack peer list used by PeerGuardian and PeerBlock
- Single listening port for all torrents
- Scheduled bandwidth limits
- Global and per-torrent bandwidth caps
- Sorting/filtering options
- HTTPS tracker support
- IPv6 support
- Local Peer Discovery support
- and many more
Windows users who wish for a change, can go for it. It is based on the latest Transmission version 2.2.
