A CUE sheet is a metadata file that describes how the tracks of a CD or other disc image are arranged. It typically contains information such as track titles, artist names, track start times, and other relevant details. CUE sheets are commonly used in conjunction with BIN files, which contain the raw data of the disc image. The CUE sheet acts as an index, allowing media players and disc burning software to properly interpret and play or burn the individual tracks from the BIN file. Without a CUE sheet, the BIN file would be treated as a single, continuous audio or data stream, making it difficult to access individual tracks. CUE sheets are plain text files and can be created or edited using a text editor. They follow a specific syntax that defines the structure and content of the metadata. The combination of CUE and BIN files provides a convenient way to archive and distribute disc images while preserving the original track information.
