A Wii U WUX file is the compressed version of a Wii U Disk Image WUD file, generated using the Wii U image compression tool to reduce the file size of WUD segmented files, which are typically around 20 GB in size. The WUX file is a compressed format that can be decompressed back into WUD format for use in Wii U emulators like Cemu, allowing users to play Wii U games on their computers.
