Hi 哲 李 , I am the developer of OneDrive Bully and thanks for mentioning my small app in a forum like this, I am really honoured. I developed the tool for the same need as everybody else in this forum and I have been using it without an issue to sync my work & home laptops for a year now without issues.
The code hasn't been updated since then as there weren't any issues reported on GitHub or on the FB Page. Feel free to try it and if you see anything missing/misbehaving please open an issue on GitHub or send me a pm on FB and I will have a look at it.
Thanks
