This post describes how to add the Print Directory feature, and how to enable printing of the directory listing from within File Explorer.

Directory List & Print Pro provides a text-based list of all your computer files. Choose the folders, drives, or directories that you want indexed and receive a complete listing of their contents.

You will now have a file in your Documents (or My Documents for XP) folder labeled kindlebooks.txt. You can open this in Notepad or any text editor and see the list of books.
