If you are storing a library of 50 to 100 games, this can mean managing over 2.5 terabytes of data. Standard compression tools like WinRAR or 7zip can help, but they are general-purpose and often slow, as they compress data at a granular level without fully understanding the structure of a disc image.
Left-click your heavy file and drag it directly on top of the wudcompress.exe icon .
WudCompress was introduced to convert these bloated images into the .wux format. By stripping away "zero-fill" or redundant data, the tool significantly reduces drive footprints without sacrificing data integrity. 2. Core Mechanics: From .wud to .wux WudCompress
WudCompress is a lightweight program (roughly 50 KB) that operates via a simple drag-and-drop interface on Windows. Its primary functions include:
If a game only requires 2 GB of space (such as Super Mario 3D World ), the remaining 21.3 GB is filled entirely with empty dummy data or duplicate sectors. If you are storing a library of 50
, but since many games do not fill the entire disc, WudCompress can often reduce the file size significantly—sometimes to just a few gigabytes. Lossless Compression
Capable of both compressing .wud source data into .wux and decompressing .wux archives back into a full .wud layout. WudCompress was introduced to convert these bloated images
For users who prefer more control or wish to automate the process, the tool can be used from the command line.
In the context of Wii U preservation and homebrew, storage space is often a concern. Wii U games can range from 2GB to over 20GB. The .wud format is a 1:1 raw dump of the disc, meaning it includes all the padding and dummy data found on the original disc. removes this bloat, significantly reducing file size without altering the game data.
