The document describes a book organizing application called "Books Organizer" that can scan a user's storage system, organize their book files, and provide additional metadata for each book like the title, author, publisher, and ratings. It works by using a wizard to scan for books, manage the book files, and retrieve online data to populate details. Users can then view their book collection organized by categories and search their library either online or offline. The app aims to simplify organizing books compared to using a default file explorer by bringing related book data together.
