How to create a Torrent file?

The following process is created using Transmission for Mac, but the method is also available under other OSes and using other major torrent clients.
Here are the necessary steps to create a Torrent.

  • After opening Transmission, the first thing that you should do is to click on the “Create” button, or go to “File – Create New Torrent File” menu (Command + N) …

  • ….Or something similar in another client. For example, the menu in uTorrent is “Create New Torrent” (Ctrl + N).

  • Then browse to the location of the file(s) that you want to share. Highlight the file(s) and click the “Select” button.

  • The next step is to customize the torrent settings. Start by adding trackers to the torrent, continue with the comment field, the “Private” option checkbox, and the “Create” button.

For those who are unfamiliar with the term “tracker“, here’s a short quote from Wikipedia:
A BitTorrent tracker is a server that assists in the communication between peers using the BitTorrent protocol. It is also, in the absence of extensions to the original protocol, the only major critical point, as clients are required to communicate with the tracker to initiate downloads. Clients that have already begun downloading also communicate with the tracker periodically to negotiate with newer peers and provide statistics; however, after the initial reception of peer data, peer communication can continue without a tracker.
You can use the OpenBitTorrent tracker for your torrent. This service is free to use.

Even though it’s possible to create a torrent without a tracker, I personally prefer to add at least one while creating a torrent file because my short experiments showed no activities in all of the trackerless torrents that I created.

The torrent creating process could take some time depending on the size of the shared file.

You can share the created torrent file easily by email since the size would be very small.

The receiver can open the torrent file using any torrent client installed on his/her computer and download the shared file.
But please remember to also open the torrent on your own computer using your torrent client and connect your computer to the internet to enable the file sharing. You will act as the seeder here. If you close the client then the download process on your friend’s computer will stop.

It’s also advisable to ask your friends to keep their torrent clients open even after they have finished downloading the file. They will also act as seeders. And the more seeders there are, the faster the download process will be.

If there are several people who have finished downloading and they continue seeding, you can disconnect your computer and the download process in other computers can go uninterrupted because the parts of the file are taken from other seeders.

It’s true that one of the biggest disadvantages of sharing files via torrent is that the torrent creator’s computer has to be connected to the net at all times. But this method is the perfect file sharing method for companies which have computers that always connected to the net.
