具体来说，我想确认：学习集（Study Notebook）以及学习集里的思维导图（Mindmap）是否也能被完整恢复？
If I back up the note database and the corresponding PDF/EPUB documents in MarginNote 4, can I fully restore everything after reinstalling or moving to a new device?
Specifically, I want to confirm whether the Study Notebooks and the Mindmaps inside them can be completely restored.
