libext2fs-wii is a port of the libext2fs driver to the Nintendo GameCube/Wii, modeled on the libntfs interface.


  • EXT2/EXT3/EXT4 file systems support
  • Full read/write, files of any size can be created, modified, renamed, moved, or deleted.
  • Compression, read/write support for compressed files
  • Symbolic link and directory junction walking
  • Journaling system

Getting the latest sources

To grab the latest and greatest copy of the sources just type:

svn checkout svn:// libext2fs-wii

Compiling and Installing

Make sure you have devkitPPC and the latest libogc installed. Then from the sources root directory, type:

make install      # or 'sudo make install' if you aren't root.

To compile a debug version with a console print out of the debug information, type:

make debug        # or 'sudo make debug' if you aren't root.


Related routines can be accessed by adding the following line to your source file(s).

#include <ext2.h>

When compiling you must also link against libext2fs. To do this, add -lext2fs to the LIBS section of your application Makefile; for example:

LIBS := -lwiiuse -lbte -lext2fs -lfat -logc -lm

For a more practical example of using libext2fs in your application, see it's implementation in WiiXplorer.
