I play with my girlfriend on our server, but she plays on her brother's account. I'm buying Minecraft as a gift for her and I wanted to know if I could transfer her advancements to the new account. I believe I would have to manage files, but which ones? Are they in the server's folder or the world's? Also, it'd be great if I could transfer her score and XP level too. I read about people using a program called NBTExplorer. Is it possible for me to do all of this?
