If you have a large amount of data you wish to burn to disc and it won’t fit on a single DVD or CD, you can make the process easier by using burning software that supports disc spanning. Here’s how to do it.

Disc spanning allows you to burn large amounts of data without having to worry about organizing it into the right size so that it fits on each disc. Many popular disc burning applications don’t support disc spanning, but CDBurnerXP does, and it’s completely free. Now you can backup any amount of files such your iTunes library, photos and movies easily across multiple with ease. The software automatically figures it out for you.
