Disc Capacity Bar

At the bottom of the program window is the disc capacity bar, which displays a graph of the current and maximum capacity of the disc. (The capacity bar appears after you have selected a burning task.) Below the graph is detailed information about the disc, such as the number of folders and files in the current project and on the disc, as well as the disc's free and used space. Use this bar to keep track of the amount of content you add to the disc.

The capacity bar may display a certain amount of used space even before you add files to be burned to your disc. This is because more data gets burned to the disc than just the files you select. This extra data includes the disc's file system, data specific to the file format you choose, as well as fixed spaces that must be retained between files, sessions, and audio tracks. The real used space is displayed on the capacity bar to give you an accurate indication of how much data can be burned to a disc, instead of relying on trial and error when filling a disc to capacity.
