So I have a few ISO/AVI file, and I want to make it into a large "ISO or AVI" instead of having all separated ones. I've googled around, and as I read of, I'm suppose to "extract" the files? Which I've tired, and don't get. Is there a simpler way? A program where I can just add the file, and then click "join" or something & It'll do it for me? Please & Thank You!
