Even with the Wii being several generations old, WBFS remains relevant for a few key reasons:
: Today, it is highly recommended to format your USB drive to FAT32 and store your games as .wbfs files inside a folder named wbfs . This allows you to use the same drive for other files (like photos or PC data) while the Wii still recognizes your games. How to Manage WBFS Files wbfs wii
Because computers cannot naturally "create" WBFS files from discs, you need specialized software. Even with the Wii being several generations old,
Before the advent of WBFS, the primary method for backing up Wii games was creating raw disc images, typically saved as ISO files. While functional, this approach was inherently inefficient. A standard Wii disc holds 4.7 gigabytes of data, yet the actual game data often occupied only a fraction of that space. The remainder was filled with "junk data"—padding used to fill the disc structure. Consequently, storing a library of ISOs required massive external hard drives, with significant portions of that space dedicated to useless filler. For a console generation where internal storage was limited and external drives were an additional expense, this inefficiency was a significant barrier to digital preservation.
