Burn To The Brim is a utility for grouping files and folders together in the most efficient way to fill up an entire CD, DVD or other medium. It can output the resulting structure to an ISO 9660 file, ready to be burned with most CD-burning tools.

The program is optimized for quick performance and considers the most promising options first. It also minimizes the search length by fast detection of dead ends. The program cuts corners whenever possible (without missing anything). Folders can be split up to a set level for more versatile splitting options.

The first priority of the program is to fill the media as well as possible, second is to minimize the number of items (so the larger, harder to fit items have preference and more items to choose from are left for the next burn).

Users can define their own custom disk formats so they can also use the program to fill other media like Zip disks and the like.
