Vildisi spent too much time on this

Why they don't go with tar or pax or plain bzip2 / xz is beyond me.
- But I guess they are too lazy to use #BitTorrent and/or #IPFS and merely want to prop up #Filehosting providers...
Jay@kkarhan @vildis It's legacy stuff from the usenet days. One file being broken allows you to just download missing blocks for it from other usenet providers so that you don't have to redownload the entire thing all over again because one piece is missing/broken on your provider. Most tools these days basically make the rar files essentially transparent anyways, so you never really need to worry about it...?
