How many pictures will fit on each type of disk (CD vs. DVD)?
The number or photos that will fit on a CD or DVD varies depending upon the file sizes of the images to be backed up. After selecting the photos you want to back up, you will see a summary that specifies how many CDs or DVDs it will take to back up the selected photos. You can then decide whether to use CDs or DVDs for your backup disks. Note that CDs hold about 700MB of data, whereas DVDs hold 4500MB worth of data.
