2. Wiimm Disc File

Wiimm Disc File

Disc image created by Wiimms WBFS Tool, a program used to manage Wii disc images; contains game data that has been extracted from a Wii disc; used to store the reduced size of a Wii game image when saved to a computer's hard drive.

Wiimm disc files can be much smaller than the size of a Wii disc image file since they do not store the unused padding space, or "holes," that are found on Wii discs. This can significantly reduce the size of Wii games when saved to WDF files.

WDF files can also be converted to Wii Backup File System files (.WBFS), which are used to store Wii games on external devices.
