Since the computer I used in our office is ancient I searched for a free burning software that will require minimum space in hard disk and ram (nero is out of the list) so after using various free burning software I finally settle in using one, the BurnAware Free. Here's a description from the developer:
BurnAware Free is a full-fledged disc burning tool – fast, lightweight, feature-packed and, most importantly, free. The program burns all types of CD, DVD and Blu-Ray discs containing data, digital photos, music and video. With BurnAware Free, you will be able to create bootable or multisession CDs and DVDs, high-quality audio CDs, make and burn disc images, copy and backup discs. - burnware.com
So what's in the freeware that makes me stick to it? You'll find out after the break.
