    In this analogy, when you add a new book, only then is that “deleted” book actually removed and replaced with the new one. Until then, it just sits there waiting, but since nothing is pointing to it, it’s hard to find.

    When someone recovers a file, what they’re doing is going book by book and reconciling the index to see if there’s anything missing. Since this book still exists, it can be recovered.
