The WBFS file system was created by Wii enthusiasts and developers as a solution for storing and managing Wii game backups. Prior to WBFS, backing up Wii games was a cumbersome process that involved creating multiple files and folders, making it difficult to manage and navigate. The WBFS format was designed to provide a more efficient and organized way to store Wii game data, allowing users to easily browse and launch their backups.
