DiscSpan is a tool that will take that a large directory full of files and automatically burn a series of DVDs to near capacity, without the need or hassle of creating individual ISOs or moving files around. It is geared more towards smaller files such as music and photos, as it cannot span a file across multiple discs. It prompts for the directory you'd like to back up, the device to use to burn, and the speed at which to burn. It analyzes the files and calculates how many DVDs are needed, while making sure no files are greater than the size of a DVD.
