Introduction

Khan Academy is a website offering thousands of free educational videos on a lot of different subjects, be it Mathematics, Science, History, Economics, Astronomy, Art history and a lot more! The Wikipedia article of Khan Academy give details information on what it is exactly.

The videos are available on their website where you can (optionally) log in, this will give you some features like tracking what you have watched, commenting and asking questions to other people, doing tests and when you pass them very succesfully, the website will optimally show you new videos instead of showing you videos that you do not need to watch because you have understood a specific subject very well. When you use their website, the team behind Khan Academy also track what you are doing so they can improve their website. There is no doubt that by using their website you can learn faster than if you download all the videos on your computer.

FAQ

How do I only download specific videos? I do not want to download everything!

One of the most useful feature with torrents is that you can download just what you need. Every torrent software has this option. In Deluge, click on your torrent and look at the Files tab at the bottom, you can right-click on folders and select “Do not download”.

When will a new torrent file be released with new videos?

There is no release dates. This torrent is voluntary work so it happens only when we find the time to make a new one. It usually happens once or twice a year.

A new torrent is out, can I download it over the old torrent I had so as to save bandwidth?

Khan Academy regularly change the structure, folder names and filenames so it is better to delete everything and start downloading the new torrent.

Why is some filenames of video cut-off?

Windows filesystem, unfortunately, has a limit of around 255 characters for the complete path with the filename. So we have implemented a limit of 200 characters for the path and the filename of each videos. The remaining 55 characters is left for the path that the user will download the torrent (i.e. C:\Users\name\Downloads).

How do subtitles work exactly?

A subtitle file, which has an extension .srt, is just a text file containing all the subtitles of a video. To be able to use it, the subtitle file must have the exact same filename as the video and be in the same folder as the video. By just opening the video with VLC Media Player, it will automatically read the subtitle file.

To copy the subtitles files in the same folder as the videos, go into the Subtitles folder, unzip the language file that you need and just copy all the folders into the folder video so as to merge them. It will place all the subtitles files in the right folder. Note that there isn’t subtitles files for every video. Unfortunately, not all videos are translated.

      Yes I’m the one seeding. It is on a seedbox with a 20 Mbps upload speed so there should be a good download speed.

        You can always watch it on youtube! Find someone with a better internet connection. It will take about 30 DVDs to fit everything, that is a lot.

    This torrent is unseeded, which is too bad because I could really use it. Can you drop me an email or something if you start reseeding, Zurd? 🙂

    • Zurd Zurd

      Sometimes this torrent goes to Pause in my seedbox. No idea why but I always restart it. I check it around once a week. It’s been running for at least the past 3 days without problem!

      Like I said below to someone else, there was a problem with the seedbox, it lasted just a few days though. We are 4 peers connected at the moment, working quite fine!

      There was some problem with the seedbox at that time which lasted for a few days. It’s been seeding fine for quite some weeks now!

    Thank you, so much. I think it would be so much better if you could include each video subtitle in the torrent also and I would be very thankful if you show me anyway that I could get all the subtitles by my self. Thank you.

    • Zurd Zurd

      I always wanted to add the subtitles too but kind of forgotten all about it!

      I will see what I can do in the next torrent!
