The WBFS (Wii Backup File System) is a custom file system for Wii game console. It works by creating a WBFS partition on a flash memory card or USB device. You can run a Wii application after you copy ISO images of the game to the partition and use a Wii USB loader. The WBFS Manager lets users transfer ISO image files to a WBFS formatted drive. You need to allocate space on your hard drive with a WBFS-supported formatting program to create a partition for use with WBFS Manager.
