What is a torrent file and how does it work?


Torrent files are files transferred between users using Torrent technology. Torrent files use the file extension .torrent. Torrent files, when added to a torrent application, can be distributed among many people without having to pay high hardware costs and server fees for specific individuals. This is because every user will provide the bits of the complete Torrent file to users who do not have these specific bits, and at the same time receive the bits they do not have yet. Therefore, torrent files can also be shared relatively quickly.


The Torrent technology was first planned and developed by Bram Cohen in April 2001. After several months of development, it was first released on July 2, 2001. Today, Cohens technology is widely used. Although there are no specific measures, it is considered one of the most commonly used protocols on the Internet today.

Behind the technology

Torrent technology is operated by a Torrent client, which sends part of the Torrent file through the Torrent protocol. For example, the torrent client can be a personal computer, and the torrent file can be any file in the .torrent format.

To start sharing, the user must first create a .torrent file (for example, File.torrent). Torrent files contain information such as the tracker, the host that distributed the file first, and metadata, information about the files in the torrent file. People who want to get information must first download the torrent file (File.torrent in this case), run it with their torrent application, and then connect to the tracker, which will give you information about where to download which bits of the torrent Command file. .

Torrent files vs. HTTP Files

Although torrent files and their sharing are technically transmitted over the network, it has its advantages over the old HTTP download style. First, when downloading a file, the web browser will issue an HTTP GET request through a TCP socket. However, torrent files will send a lot of small data requests through many TCP sockets. In addition, HTTP will download sequentially, downloading first; however, seeds are downloaded randomly, and any highly available ones will be downloaded first.

This is why the torrent file has its advantages; it doesn’t require a lot of financial support, has a higher degree of redundancy, and is more resistant to potential abuse from fast-paced crowds than is often the case with HTTP. However, as with all things, there are downsides. The download will take some time to run at full speed because it may take some time to connect with other peers. Also, it takes time to become an effective loader. Don’t forget that although torrent file downloads will reach very high speeds, as torrent file bit availability decreases, the speed will eventually drop at the end of the download.

Torrent and file sharing

First, the user browses the Internet to find torrent files. After obtaining the torrent file, the user will connect to it through the torrent application and connect to the tracker. The user will then start downloading from the planter and a group of peers called groups. If there is a planter, the user will directly connect to the planter and start downloading, but will eventually start to exchange files with other peers, thereby reducing the load on the planter.

Torrent File Application

Surprisingly, Torrent files are widely used by many people and some companies today.

> Some bands like Ween use torrent files to distribute their free albums

> Podcasts increasingly use .torrent files to meet these high requirements for broadcasting MP3

> Americas Army games use torrent files to publish their games Updates and patches

> A large number of free and open source software uses torrent files to increase project usability and awareness

Torrent file limits

Although torrent files seem to be another good way to download and share files, they have some limitations, such as security issues .

> IP address exposure – Using torrent files can cause anonymity issues because all IP addresses of current and possibly former group users can be found and abused

> Internet speed – Broadband is best used when sharing torrent files, so dial-up users cannot take full advantage of torrent technology

> Leeching Question: Although sharing torrent files is good, there is not much incentive behind it. Therefore, there is no real reason to continue seeding after the download is complete. To solve this problem, some torrent sites have started to limit the download speed of users who upload infrequently.

Free torrent application to download torrent files

There are currently quality free open source and paid products on the market for downloading torrent files.

> BitTorrent: BitTorrent is the first official Torrent client created by Bram Cohen himself. It is compatible with major operating systems such as Microsoft Windows, Apple and Linux.

> Azuerus (Vuze)-is also a widely used torrent client, first released on SourceForge in June 2003. Released under the GNU General Public License, Azuerus is a continuously developed free client.

> Torrent (uTorrent): uTorrent, also known as microTorrent, is a torrent client written in C++. Due to its small size but powerful interface, it is another widely used free torrent client. It was first released by BitTorrent, Inc. and Ludvig Stigeus on December 7, 2006, but due to the popularity, scale and functionality of the application, it was later fully acquired by BitTorrent, Inc.
