My kindle app will not allow me to add any more books. It says it is full until I delete some. How do I do that?
In your device's Kindle app, in the menu of titles, touch and hold a title you no longer want. This will display a context menu; choose Remove from device. The title will remain in your Kindle Cloud, but clear up local memory on your device. You can redownload the eBook at any time by using the menu to navigate to All Items.
Audiobooks are larger files than graphic novels or picture books and fiction (without pictures) have the smallest files of all in ebooks. The type of digital book file may affect how many fit on any one device's storage.
