I try to use 7zip (9.20 - 9.30) on windows command line with multi thread options
(-mmt=on -mmt=2) without luck.
At the GUI there is a multi thread options thats run out-of-the-box.
How can I use multi thread on command line?
It seems to be an Windows XP Problem.
On an windows 7 64bit it use all CPU's on command line.
