DVD Span is a backup tool for writing the contents of large folders to multiple DVDs. DVD Span can automatically determine the best organization of each disk in order to fit the maximum amount of data on the minimum number of disks. DVDSpan is a great tool for backing up your music collection, photos, or even your entire hard disk to DVDs. And because it produces regular DVDs (or CDs), no special software is required to read or restore your backups.

To install:
unzip and copy files into the folder of your choice.

Limitations:
* 7 disks per span.
