I have hit a slight snag in my coding process, it seems that unless I use 64bit code, I might not be able to overcome a 2GB file size limit. I am currently using NSData as my way of peeking around files, but that has a file size limit of 2GB unless I am coding for a 64bit application which may be a little more than I can handle now. I am looking at some other options but it seems that creating an iso utility may be held back until I can come up with a solution. I could go 64bit, but that would just be one more thing to learn and may be too difficult at the moment. On top of that, it may leave some users behind (even though all current Apple computers are 64bit and have been for quite some time).
