Well, I can at least look at it. I'm not exactly sure how I did it last time, or how much of it I kept.
@George King - Here are x32 and x64 ntfs2btrfs builds compiled on Win10 with msys2/mingw. I tested that they will run on the 32 and 64 bit versions of Win 7 PE. https://www49.zippyshare.com/v/yMDBa3sQ/file.html I will need to reinstall a 32 bit XP VM and see what else I can do. Can't promise much - I dislike working on obsolete Windows versions.
@CaptainKirk1966 Thanks for them! Its probably enough to run it under Windows 7 PE as its minimum where is done XP2ESD installation done. Important will be to compile latest BTRFS driver to support XP-10 with Quibble. I hope you can achieve it too.
