I don't know why this happens so much, but it seems like a lot of torrents are packed as rar files. Why is this? This was useful back in the 90's with dial up and IRC/FTP, when you could lose connection at any time and lose a 700mb file, but in the modern age of high speed internet and bittorrent with built in error checking and resuming, this is way past redundant. Using rar hurts torrents because people (me included) will stop seeding early because the stupid rar files take up an extra 20gb of space per torrent. Using rar for something like an iso is a waste because you need to download the whole thing anyways and it is also stupid for mp3 because you can't pick what you want ahead of time. Can anyone justify the use of rar?
