31.7.2 Splitting an Image

You can split an image file into separate files so that you can span the entire image across several
CDs or DVDs.
When you split a device image and span it across several CDs or DVDs, you are essentially creating
a base image on the first CD or DVD. The remaining CDs or DVDs are add-on images.
Because images are split by placing individual files into different images, an image cannot be split if
it contains any single file that is larger than the specified maximum file size.
To restore a device image that has been spanned across several CDs or DVDs you should restore the
first CD or DVD before restoring the remaining CDs or DVDs containing the add-on images. For
more information, see "Manually Putting an Image on a Device" on page
Restoring split Images is done using bundles, such as restoring a base plus add-ons. For more
information, see "Creating an Add-On Image" on page
To split an image:
1 Click Tools > Split Image.
2 Fill in the fields:
Image File to Split: Enter or browse to an existing base image file to split.
Directory to Store Split Images: Specify the location and filename under which to save the
split-image files, or click the browse button next to this field to locate and select it.
