Inside books.eidos, the Books table has fields such as Title and Status. Each record represents a book. The Reading view saves its filter and layout.
When you move the data, include its referenced local files.
The diagram shows a possible Space structure with a book list, a note, and an image. Opening an empty Space does not create these example files.
Lite automatically reopens your last Space on startup. The Space selector appears on first use, when there is no remembered Space, or when the last folder cannot be opened. Closing a Space window keeps the selector closed. Switch Spaces at any time from the Space name at the top of the sidebar.
