The primary innovation of the WBFS format is "scrubbing." The WBFS Manager software identifies the padding data (dummy files) on the game disc and removes it. This process is distinct from standard file compression (like .zip or .rar). Instead of compressing the data, the scrubbing process replaces the dummy data with zeroes, allowing the file to be compacted significantly without altering the game code itself.
For example, a game like Wii Sports is approximately 0.35 GB in size. A raw ISO dump would be 4.7 GB. When converted to WBFS, the file size is reduced to roughly 0.35 GB, matching the actual data footprint of the game.
If you have files you need to manage, you will need specific software. Note that these tools are for managing backups of games you own.
While WBFS was the dominant format for many years, it has largely been succeeded or supplemented by the CISO (Compressed ISO) format. WBFS was developed by the homebrew community to
