We make Express Burn free in the hope you will like it so much you will decide to upgrade to Express Burn Plus. The plus version includes the ability to burn Data DVDs and Blu-ray Discs (supports DVD-R, DVD-RW, DVD+R, DVD+RW, BD-R, BD-RE, BD-R DL, BD-RE DL) and more advanced features like the ability to create and record ISO images and, for audio CD, support for many more file formats (the basic version only supports wav and mp3).
