The file extension. Invented by Wii homebrew legend WiiPower, WBFS (Wii Backup File System) is a custom file system designed to store Wii ISOs on USB drives without fragmentation. Unlike FAT32 or NTFS, WBFS is dumb and efficient. It strips away all file allocation table overhead. Today, most users convert scrubbed .wbfs files to .iso or load them directly via USB Loader GX or CFG Loader.
