WBFS (Wii Backup File System) is a very simple file system that can only store Wii images at a single directory level. WBFS was explicitly developed in early 2009 by Kwiirk and Waninkoko for the use of USB loaders and initially used only as a partition (similar to a FAT, NTFS or ext234 partition). The developers made the access and management functions available as a C source code library LIBWBFS under the GPL2 license, so that third parties building on this library could quickly develop their own USB loaders and WBFS managers. The WBFS managers are needed because no operating system can handle WBFS partitions.
When Wiimm started developing his WBFS manager wwt (Winnings in Wiimm's ISO Tools) for Linux in late 2009, he minimally modified the LIBWBFS for testing purposes, so that WBFS files could be managed on other file systems. It was then Oggzee, the developer of the CFG Loader, who discovered these types of WBFS files for his USB loader months later. He then took over Wiimm's naming "TITLE [ID6] .wbfs" and introduced the splitting of WBFS files larger than 4 GiB. Meanwhile, all current USB loaders and WBFS managers can handle WBFS files.
In developing its tools and a consistent code review of the LIBWBFS, Wiimm discovered about a dozen programming errors in the LIBWBFS, 3 of which were so serious that they could make the entire WBFS archive unusable. The bug fixes were published and discussed on GBAtemp [1]. Because these bugs were discovered by mid-2010, it can be assumed that all loaders and tools that are older can definitely handle WBFS errors and destroy content. The popular WBFS Manager 3.0, released in April 2009, belongs to this category, so it is not recommended to use it.
