A TORRENT file is an information file for downloaders that support the TORRENT protocol. Torrent itself is a file-sharing protocol for the sharing of files. It's especially good for large files because it distributes the load over many users, while with http or ftp, the load has to be carried by a single server. However, TORRENT only works really well if there are enough distributors who also offer the appropriate file.
In addition to the illegal use of TORRENT files are now also offered by some download portals (for example for game patches) and many other websites. Games also use this technique (e.g., Company of Heroes, Blizzard Downloader)
A TORRENT file is usually very small, because in the TORRENT file are only information about the file, its size, checksum and information about so-called trackers. These files can be downloaded with any browser.
To download the actual file, you need a TORRENT download program (torrent client) or a browser that supports this protocol. If it is often loaded and offered files, the download rate is correspondingly high. If there are no distributors (seeder), you will not get the file. A TORRENT file is not a guarantee to get a specific file.
Most often resolving problems with opening TORRENT files is very simple. Just install an appropriate program that supports such files. All of the listed programs support TORRENT files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of TORRENT files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate TORRENT files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the BitTorrent applications is not on the list, select "Browse" option in order to manually locate the directory where BitTorrent has been installed.
Sometimes problems with opening TORRENT files may not lie with the application itself, but can arise due to other causes, such as:
