If you downloaded all of them (z01 to z10 & one file that's a zip (so 11 files total)), tell your unzipping program to unzip only the .zip file (make sure the z01 to z10 are in the same directory), that should do it. (right click on the .zip and tell it to extract)This might be an easy fix but im really not tech savvy. But each time I try to extract the files it keeps saying I need the next volume?
