A few days ago I set up a computer again in the circle of acquaintances and was then asked for a recommendation for a burning program. I have a favorite that I can suggest to everyone – ImgBurn. It is limited to the most important functions, as the name suggests, it makes or burns complete images. With a few megabytes of file size, it's wonderfully small and still free.
Immediately after installation, you start ImgBurn and land at the start screen and then you can choose whether you want to copy all files from a disk, create an image from a disk, or create a disk from an image. As I said, everything is totally easy and with just a few mouse clicks you start the software or the desired function.
