When you get an unknown format of CD/DVD image file and don't know which burner to use to open it, or all the popular CD/DVD burning programs can not recognize this file, we can use CDmage to extract files directly from this image or convert it to some common disk image formats. In short, it lets you have no CD/DVD-ROM images that you can't burn, and can be regarded as an indispensable tool when working with CD/DVD images.
