with 2 comments

Features implemented or bugfix since V0.53:
    1, Ext4 extent writing support (developed by ngkaho1234 @ gmail.com)
       See his repository for more details:
    2, Size manipulation and i/o path revised for support of indirect and
       extent-based mappings
    3, 16T volume supported (tested and confirmed with 4T volume)
       Version 0.53 and previous versions only support up to 2T volume
       ticket: https://sourceforge.net/p/ext2fsd/bugs/134/
    4, Deletion acceleration: truncation optimized for indirect-based files
    5, Size-expanding disabled in IRP_MJ_CREATE for better performance.
       Windows sometimes would truncate file size back to 0
    6, Support Volume exclusive-open for e2fsprogs utils. Any attempts
       will be denied while EXT4 volume is being checked (e2fsck).

    The driver may crash your system and ruin your data unexpectedly,
    since there might be software conflicts and I could only test it
    on some of the popular platforms. You should use it with care and
    use it at your own risk!
