Yaz0 is the only compression algorithm that is used in ''Breath of the Wild''. Many resources, such as [[ | Yaz0 is the only compression algorithm that is used in ''Breath of the Wild''. Many resources, such as [[actor pack]]s and [[BYML]]s, are compressed. However, content files that are inside of archives that have already been compressed (such as [[ActorParam]] files) are typically uncompressed. | ||
Extensions that start with an <code>s</code> indicate that the file is compressed using the Yaz0 format. ''For consistency reasons and to reduce visual noise, {{SITENAME}} chooses to omit the prefix when referring to file extensions.'' | |||
