I followed the instructions to the letter (deleted the personal tag and added the tag instead), deleted the previous Mobi version of the ebook from my 'books' subdirectory on the Kindle Fire and placed the newly Calibre converted version in that same subdirectory. Since I was having the issue of the book not showing under the Books tab of my Kindle Fire after moving the file to my 'books' subdirectory under the 'Internal Files' of my Kindle Fire 7, I found this article and downloaded Calibre. I downloaded a Mobi book from Project Gutenberg to my Windows 10 laptop. Delete the default ' ' and keep the Personal Doc Tag blank. Click 'MOBI Output' at the left menu and find 'Kindle Options' at right side. Set the Output format as 'MOBI' (or 'AZW3'). Select all books in the list and choose 'Convert books'. Open Calibre and choose 'Add book' to add MOBI ebooks. It can convert MOBI to MOBI without quality loss and remove the personal document tag at the same time.ĭownload and install the latest Calibre on your PC. Calibre is the right tool for doing this job. Some MOBI ebooks are added personal document tag when generated so that the Kindle Fire will recognize them as documents but not ebooks.Īfter knowing this, you may ask 'How about removing this personal document tag'? Yes, this is exactly we need to do. We know that the Docs category is used for storing personal documents like PDF, HTML, TXT or other documents sent by Amazon 'Send to Kindle' service. It's totally a mess! So it's better to make MOBI files display as books on Kindle Fire, not docs.īefore we start, we should figure out why the MOBI books display in 'Docs'. Or just think about the scene that your favorite ebooks are mixed with some uncorrelated documents. This situation causes some inconvenience of managing a large number of ebooks as you have to browse in two different categories. But one problem I ever met when reading MOBI e-book on Kindle Fire is that some MOBI ebooks don't display in the 'Books' category but 'Docs' instead. The popular Amazon AZW e-book is just based on MOBI.
