I'd like to find the technical details for a book I have on my Kindle Paperwhite 2, i.e. the file format or filename. Can it be done (on the device)? I can only see "Book Description", but that refers to the Kindle Store entry, not the local file details.

The context is that I've been testing the capabilities of Calibre to convert ePub to the kindle (don't worry Amazon, I still love you and will buy your e-books. But some things are only available in ePub, we need to be able to use it. Not to mention the library e-loans). I used the Calibre Quick Start Guide as a test case, converting to both the main kindle formats, mobi and azw3.

On the device, one of the converted books has normal formatting, the other has cruddy formatting. The poorly formatted one also seemed to have slower page turning, it felt "heavier" (although file sizes are about the same). I'm pretty sure the azw3 is the good one (it's supposed to be able to handle more complex formatting), since I can also see some of the misformatting in the mobi version using the Calibre e-reader on the computer.

But I'd like to be able to confirm from the device itself that the mobi version is the poorly formatted one. Is there anyway to do this? On the list of books both of them look identical, no way to distinguish them.
