Fichier Torrent


In the BitTorrent file distribution system, a torrent file or meta-info file is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms.[1] A torrent file does not contain the content to be distributed; it only contains information about those files, such as their names, folder structure, sizes, and cryptographic hash values for verifying file integrity. Torrent files are normally named with the extension ".torrent".




fichier torrent



A torrent file acts like a table of contents (index) that allows computers to find information through the use of a BitTorrent client. With the help of a torrent file, one can download small parts of the original file from computers that have already downloaded it. These "peers" allow for downloading of the file in addition to, or in place of, the primary server.


The BitTorrent system has been created to ease the load on central servers, as instead of having individual clients fetch files from the server, BitTorrent can crowd-source the bandwidth needed for the file transfer and reduce the time needed to download large files. Many free/freeware programs and operating systems, such as the various Linux distributions offer a torrent download option for users seeking the aforementioned benefits. Other large downloads, such as media files, are often torrented as well.


A small torrent file is created to represent a file or folder to be shared. The torrent file acts as the key to initiating downloading of the actual content. Someone interested in receiving the shared file or folder first obtains the corresponding torrent file, either by directly downloading it or by using a magnet link. The user then opens that file in a BitTorrent client, which automates the rest of the process. In order to learn the internet locations of peers who may be sharing pieces, the client connects to the trackers named in the torrent file, and/or achieves a similar result through the use of distributed hash tables. Then the client connects directly to the peers in order to request pieces and otherwise participate in a swarm. The client may also report progress to trackers, to help the tracker with its peer recommendations.


A torrent is uniquely identified by an infohash, a SHA-1 hash calculated over the contents of the info dictionary in bencode form. Changes to other portions of the torrent does not affect the hash. This hash is used to identify the torrent to other peers via DHT and to the tracker. It is also used in magnet links.


The new format uses SHA-256 in both the piece-hashing and the infohash, replacing the broken SHA-1 hash. The "btmh" magnet link would contain the full 32-byte hash, while communication with trackers and on the DHT uses the 20-byte truncated version to fit into the old message structure.[2] It is possible to construct a torrent file with only updated new fields for a "v2" torrent, or with both the old and new fields for a "hybrid" format. However, as a torrent would have different infohashes in v1 and v2 networks, two swarms would form, requiring special handling by the client to merge the two. In addition, as v2 adds keys to info, there can be no [3]


A core feature of the new format is its application of merkle trees, allowing for 16KiB blocks of a piece to be individually verified and re-downloaded. Each file now always occupy whole piece sizes and have an independent merkle root hash, so that it's possible to find duplicate files across unrelated torrent files of any piece length. The file size is not reduced, but the info dictionary required for magnet links are (only in v2-only torrents).[3]


A torrent file can also contain additional metadata defined in extensions to the BitTorrent specification.[4] These are known as "BitTorrent Enhancement Proposals." Examples of such proposals include metadata for stating who created the torrent, and when.


The specification recommends that nodes "should be set to the K closest nodes in the torrent generating client's routing table. Alternatively, the key could be set to a known good node such as one operated by the person generating the torrent."


In BEP-0017, a new key, httpseeds, is placed in the top-most list (i.e., with announce and info). This key's value is a list of web addresses where torrent data can be retrieved. Special server support is required. It remains at Draft status.


Private torrents are to be used with a private tracker. Such a tracker restricts access to torrents it tracks by checking the peer's IP, refusing to provide a peer list if the IP is unknown. The peer itself is usually registered to the tracker via a gated online community; the private tracker typically also keep statistics of data transfer for use in the community.


Decentralized methods like DHT, PeX, LSD are disabled to maintain the centralized control. A private torrent can be manually edited to remove the private flag, but doing so will change the info-hash (deterministically), forming a separate "swarm" of peers. On the other hand, changing the tracker list will not change the hash. The flag does not offer true privacy, instead operating as a gentlemen's agreement.


BEP-0030[10] extends BitTorrent to support Merkle trees (originally implemented in Tribler). The purpose is to reduce the file size of torrent files, which reduces the burden on those that serve torrent files.


This wikiHow teaches you how to "open" a torrent file. Torrent files are essentially links to online information which allows you to download a pertinent file or group of files. You'll need a program such as qBitTorrent to open a torrent file. You can open torrent files on Windows, Mac, and Android platforms. You can also open them on an iPhone or iPad, but it will require a different set of steps, as Apple has banned torrent apps on its App Store.


The Pirate Bay est apprécié pour sa grande communauté, qui assure au moins un seeder sur presque tous les torrents du site, quelle que soit leur ancienneté. Nous avons essayé de télécharger des titres obscurs datant de plus de dix ans et nous avons constaté que des seeders partageaient toujours ces fichiers.


Pour tenter de tirer profit de vos clics, les sites de torrents afficheront un bouton plus visible qui ne lancera pas le téléchargement du fichier torrent, mais un logiciel différent et sans rapport avec celui-ci.


Créé par Bram Cohen en 2011, le système aujourd'hui appelé BitTorrent est capable de distribuer des quantités importantes de données à différents utilisateurs. Une fois sur votre ordinateurordinateur, le fichier Torrent se comporte comme n'importe quel autre fichier. Il a notamment permis le téléchargement de LinuxLinux via son protocole. Certaines applicationsapplications ou logiciels utilisent un protocole Torrent, c'est le cas de Mozilla ou du navigateurnavigateur Opéra 9. Ce protocole vous permettra de télécharger davantage de données en vous récompensant. En effet, avec lui, plus vous partagerez et plus vous recevrez de données. Le principe de base repose sur la multitude d'utilisateurs, plus il y a de téléchargements, plus les prochains iront rapidement et seront efficaces.


Pour télécharger un fichier Torrent, vous devrez tout d'abord rechercher un fichier Torrent à télécharger notamment via un annuaire spécialisé sur Internet. Il vous suffira de taper votre recherche suivi de Torrent. Ensuite, vous devrez télécharger le fichier en .torrent sur votre ordinateur. Puis, vous devrez ouvrir le fichier. Pour cela, il vous faudra posséder un logiciel comme Big Torrent ou uTorrent qui sera nécessaire au téléchargement des fichiers et à leur ouverture. Ce logiciel est gratuit et se trouve facilement sur Internet. Le logiciel commence alors à rechercher les ordinateurs qui contiennent des fragments de votre fichier et commence alors à les télécharger sur votre ordinateur. Une fois le fichier complètement téléchargé, gardez-le en stock et ne supprimez pas votre téléchargement, cela permettra à d'autres de le télécharger depuis votre ordinateur. Plus vous téléchargerez en .torrent, plus vous augmenterez votre ratio et plus vos téléchargements iront vite.


2. Vous vous retrouvez avec un fichier en .torrent sur votre ordinateur que vous allez devoir ouvrir avec votre client BitTorrent préféré. Pour ce faire, effectuez un double-clic sur le fichier, puis cliquez sur le bouton Ajouter .
