Canonical resource path
Breath of the Wild uses canonical resource paths to define the locations of its content files. These paths generally treat the content directory as the root directory of the path.
However, if the file is inside a SARC archive, then that archive is treated as the path's root. This does not apply to nested SARCs (e.g. content/Pack/Bootup.pack/GameData/gamedata.ssarc) — files inside these archives do not have a canonical resource path.
