I presume <a rel="nofollow" target="_blank" href="http://kernel.org">kernel.org</a> knows this. Why doesn't people use e.g.: XZ?<br>
<br>
This is the same as in PDF's. DJVU files could be amazing too. They could compress [convert] a 400 MByte PDF to a 20 MByte DJVU. Amazing.<br>
<br>
Why don't these technologies spread??</blockquote><div><br></div><div>most have no idea about that. do you know the level of compression used in .7z? </div>
