The full path of the book is used as the key in the internal database. Details of the books are stored in the database. This include the reading status and the bookmarks. When a book is renamed, the device sees a missing book and removes nearly all details of the book from the database. Then it imports the book as a new book.

You can intercept this by updating the appropriate database records when you move the books. It isn't to hard, but not something I've bothered doing.

But, as you are talking about epubs, there is an alternative. For epubs in the main memory, as well as the database, the annotations are written to a file. This is done by the Adobe RMSDK that is used by epubs. This is simple as you need to rename the annotations file. But, the file is only read when you open the epub. Until you do this, it will look like the books do not have any annotations.

For this, the annotations file is in the directory "Digitial Editions/Annotations". That contains files with the extension "ANNOT". The name and path to them is the same as where the epub is relative to the root directory of the driver when it is mounted on a PC. You can rename or move the files with no problems.

Wonderful. Thank you DavidFor, I will try that last way.

Even though, I know, Kobo is not so 'relaxed' with folders (you're right, JSWolf) and it shows the ebooks the same way despite of their real location, I find it useful to manage them, when considered as files, into somewhat a hierarchy of folders and sub-folders.

And this is in addition to working with "Collections", of course (Collections still represent an invaluable tool to classify our epubs and to keep them sorted within the Library).

The fact is that I use my Kobo to grab and read articles from online newspapers, mainly, and after reading I usually move the more interesting ones to a separate folder, called "Archive", to better keep them safe, while I delete the others some days after the reading, or just immediately after.

I make use of Annotations, too, and it's useful not to lose them when I move the files.
