How to merge files .Iso downloaded from pando?

Do I have since downloaded a program, it is divided into two parts, both sides are .Iso. How can unite these two parties?

Thanks friends

do not understand .. come on. iso? I believe that good is to unite the Ax .. but not if you serve ..

Rather, it occurred to me to use Daemon Tools to emulate. iso and put all the files from both sides in a folder on your desktop ..

. then use Nero to burn a. iso again that contains these files off of 2 that pando ..

Another thing you can do is:

With the Magic Iso, once open to get the two Magic ISO Iso files and create a folder on the same magic or if you want to do backup because they do not create the folder.

Once the two already put in an iso now what record or save it as you like.
