Image file
An image can be made up of one or more image files (*omg). If, for example, the disk where you want to save the image isn’t large enough, you can split the image onto multiple disks. When you split your image onto several disks, a new image file will be created on each disk and together, these image files will be parts of one entire image. It’s important to number the disks (CD/DVD) in case you want to later restore a drive using the image, or use it as a base for an incremental imaging.
