I think you should look at your internal SD card at the folder Android/data/com.amazon.kindle/files/...
I wish it was so simple! I have a rooted Galaxy 4 tab on which I have downloaded books from Amazon and Google Store. I can read these books allright both with the Play Books app and/or the Kindle app ,so the books must be there, but they are NOWHERE TO BE FOUND in my tablet under their titles in the File manager App ( My Files and/or ES Explorer).
The reason why I want to find the location of the Amazon and Kindle books is that I want to read the Google Books with the Kindle Reader app, which has a better interface. I cannot do the copy/paste operation until I know the respective locations. I might eventually have to do some conversion, but at this point I am stuck, if I don't know where these books are.
I have been gong crazy for 2 days!.
All I found in the Android/data/com.amazon.kindle/files/...you suggested are numbered files, NO TITLE . They might well be books, but their size is extremely small: only 1-2 bytes and they can't be opened!.. At some point I have come across " emulated" storage. I don't know what it means, unless it is a way to make the books..invisible! I have also looked in all other possible places, unsuccessfully. I can read the books, but their titles are not in the file tree!
