This is the software publishers description:

Active@ ISO Burner is a freeware application that will allow you to burn an ISO image file to CD-R, DVD-R, DVD+R, CD-RW, DVD-RW and DVD+RW.

Many products are posted as ISO-9660 image files. An ISO-9660 image file is an exact representation of a CD or DVD, including the content and the logical format.

The most common use of an image file is to write it to a blank CD-R or DVD-R, resulting in an identical copy of the original disc including file name and volume label information. ISO image files may also be opened and their contents copied to a local folder, much like ZIP files. ISO files may also be virtually mounted and accessed as a device.
