I use UltraISO but here lately is been getting slower and less reliable. For example, I just tried extracting a Install.wim from a ISO and it kept getting messed up during the transfer and was fairly slow. Another example is how slow its getting opening ISO's. I used 7zip, it opened the ISO and extracted the install.wim fairly quick. Someone please suggest a better ISO client, payed or freeware, just has to be good.
