An image can be split into multiple image files. If a disk doesn't have enough space to contain a full image of your selected drives, you will automatically be requested to enter another target location. It is also possible to manually set the maximum size of an image file before creating the image. If the image being created is larger than the entered file size, additional image files will be created.
This function is especially useful when you plan to burn your image onto a CD/DVD at a later time. Sometimes a CD/DVD is not large enough to contain the entire image file. We recommend your limiting image files to the size of the blank CD/DVD onto which you will be writing your images.
The image file can also be split at a later time using the Convert image file function. It is, however, recommended to split images at the time they are created to avoid any confusion that may arise.
Under Drive operation/Imaging options/File size/Split image into smaller files with fixed sizes you can specify the size of individual image files.
