What is a .torrent file?

Torrent is a metadata file for BitTorrent — containing file information and tracker URLs for peer-to-peer downloading, not the content itself.

What is it

You have a .torrent file — a small metadata file that coordinates peer-to-peer file sharing. The torrent itself doesn't contain the shared content. It contains information about the files (names, sizes, checksums) and tracker URLs that help your BitTorrent client find other people who have the data.

BitTorrent's genius is that downloaders simultaneously become uploaders. Instead of one server straining under demand, every peer shares pieces of the file with every other peer. The more popular a torrent, the faster it downloads. This architecture is perfectly legal — it's used by Linux distributions, game launchers (Blizzard, Steam for initial downloads), and legitimate file distribution. It's also used for piracy, which is why "torrent" carries a stigma it doesn't entirely deserve.

qBittorrent (free, open-source) is the recommended client — clean, no ads, no bundled malware. Transmission (free) is excellent on macOS and Linux. Avoid uTorrent (once the standard, now ad-infested). Magnet links (starting with `magnet:`) are replacing .torrent files — they encode the same information in a URL, eliminating the need for a separate file.
