About

This is a branch of the Ext2Fsd project by Matt Wu where I try to implement support for metadata
checksums and jbd2. I have also updated the project so it can be compiled with Visual Studio 2017
and Visual Studio 2019. This is work in progress. If you need a stable driver you should get the
latest official release from http://www.ext2fsd.com. If you want to try this branch you should
still install the oficial release and then copy this driver over the old in \windows\system32\drivers.
