There's a reason everyone used ZIP compression. It's a standard, and widely supported. 7z files aren't.


.zip is also ancient and inefficient (space-wise) compared to newer compression methods such as bz2, 7z, and xz - time to get out of the stone age eh?

I've been using 7zip (software) exclusively for all my archiving needs on Windows for years now - it creates ultra-tight .zip files too for those who need compatibility.

So why didn't they use it create an 'Ultra-tight' standard openable on everything .zip file? Instead of something that requires the user to spend 5-10 minutes finding some obscure often strange program that opens it?

They want people to try this, why add the additional step? to save 4 or 5 MB of a 216.3MB download?

You don't have 7z on your Linux systems? It's better than unrar at least. It can decompress most anything, and follows the magic code method to determine which algorithm the file is compressed with, like BSDtar does. It does not have the stupid GNUtar dependence on file extensions.

7z has to follow the magic key method because it analyzes the files to be archived and uses one of multiple algorithms to compress the files. It could be compressed by either LZMA or bzip2.

7-zip is THE BEST lossless data compression program on Windows.

Get with the times.

If they wanted something really esoteric, they would have compressed the file in a PAQ* compression, which would give them awesome compression, but take all your system resources and 4 days to decompress.

Maybe because they're working on a research OS, so the idea of an "extra step" as tiny as installing 7z isn't considered a big deal... because it isn't.

Yeesh.
