I liked to provide .zip= extension because BZip2 support it, and it is fine for multiplatform usage= , in 100% you can unzip it in Windows, Linux and OSX too. So, my new wic.7z= ip can operate in 100% CPU load in each 8 cores of my CPU, therefore this i= s the best for making a .zip file for wic image. But if someone wants to us= e any other mode, they can do with variables overriding. --8JirIFZLImAMfGxVUEqH Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: quoted-printable
