Better than xz?
And what's the difference?
I alwasy though 7zip was a bit sketchy like rar archives, zips are more common on windows and on linux everywhere I see there are either gz, bz2 or xz.
- user-the-name 6y agoxz is based on LZMA, which was originally introduced by 7-Zip. xz is a much simplified version of the massively, insanely over-engineered and frankly impossible to implement 7-Zip format.
- hcs 6y agoxz doesn't have BCJ2 (though it does have an earlier BCJ filter), which allows for somewhat better compression of exes. BCJ2 produces separate streams which independently compress better. See for instance https://bugzilla.mozilla.org/show_bug.cgi?id=1514357 https://bugzilla.mozilla.org/show_bug.cgi?id=1514357, saves almost 10% on a Firefox installer (which uses 7-Zip) vs the complete update .mar file (which uses xz/liblzma).
