Build them with what? what tool or software?
I've extracted the rar files, using winrar, and the result was many 15,000 byte files, each ending with a 3 digit extension (.001, .002, .003, etc.)
I've tried what was said above: I selected all files and, from the right-click menu, I selected 'Add to file_name.rar' which took over 2 hours to complete, then I ended up with a 700MB rar file. The problem still exist: its not an iso file. How can I convert it to ISO?
Can alcohol 120% burn a CD using a rar file?
Or can I simply change the rar file extension to be iso?
