Cobo, Install Creator doesn't have that good of compression ratios. For example, I wanted to make an installer for all the maps I had for other people in my dorm so they didn't have to download them at 2 k/sec in-game. I forget how much it compressed it, but it took all day and didn't do much for the file size. I said "forget this" and zipped them in a 7z file, and cut the size in half at a much faster, and efficient, rate.
