To make downloads easier for those who have slow internet connection, the ISO file is split into multiple small parts. Each split part can be downloaded separately and joined locally on your machine.
You can easily join the split files using a utility called HJSplit. It is available for Windows and Linux.
Download all the parts of the file and they have extensions ending in .001, .002, .003 and so on. Make sure all of the parts are in the same directory. Run HJSplit and select the Join option. When it opens a file dialogue, only the first part of the file ending in .001 is visible. Select it and click join. If all the parts are available, the join process should complete successfully and you must find a single large ISO in the same folder. If you need help, please follow instructions on this page.
Additionally on Linux, you could join the files from terminal using the lxsplit utility. Open terminal, navigate to the directory where all the split files reside and execute the following command to join the files.
lxsplit -j xer0conf-xxxxxxxx.iso.001
(xxxxxxxx represents the release date of the ISO)
At the end of the process you must find xer0conf-xxxxxxxx.iso file.
With torrent you will also have to seed (upload) as much as you download, so that way you may be downloading 2GB of a file but you also have to upload about 2GB or more, that is 4GB (leeching+seeding) and counting! Using torrent protocol to share files is a good idea, when there are more participants and the responsibility of seeding (uploading) is equally distributed on everyone.
Right now, there aren't many active participants on torrent and so, if the participants grow in near future, sure we'll make it available on torrents as well.
Another way of looking at it. Lets say, you are trying to download something like a "Documentary on an Alien Life". That movie isn't gonna change everyday nor the director will decide to re-shoot a particular scene again and upload it on torrent. Once the movie is made, even after 5 years the story, the situations, the scenes will be same. So even after years, you could find people seeding (uploading) it on torrent.
But with xer0conf OS, the ISO released is usually a compilation of the most recent kernel, app updates, critical patches etc and so, the next kernel release may be in a week or may be in a month and thats why even if few people decide to share it on torrents, they may still be sharing an old compilation and not the latest one. And not everyone will readily just adapt to the most recent release and in such case, the number of participants on torrent with the latest copy of the OS may be in very less number and may be from a different timezone making it difficult to be available round the clock for seeding.
