Q:"How can I split a large ISO file? I have a 6 GB .ISO file (a PC game) that I would like to split into two 3 GB files so that it would fit into 2 DVDs. How can I do this? Is there some application or command that can do the job? And after I split it, how do I merge it back together later?" - Soul from Super User Community
