With WBFS, your Wii digital library becomes portable, organized, and ready to play in minutes.
A WBFS file is a compressed version of a Wii game disc. While standard Wii discs are roughly 4.7GB (DVD size), many games don't actually use all that space. The WBFS format "scrubs" the unnecessary padding data from the ISO, leaving only the game code. Reduces file sizes significantly. wii games wbfs
