as of 4/2015 OS X Kindle App: Where are the books located? After I updated my Kindle for Mac app 2 mos. ago I can no longer find the azw book files on my Mac to convert them so I can read them on my KOBO ereader. I use to find them in a My Kindle Content file but that has disappeared. I have Ult. DRM &amp; Calibre but they won't work without the azw files, and I can't find them on my mac anymore. Can anyone help me?
The answers on this site about this are years old &amp; do not apply to my problem.
Kindle.app now uses the Apple Sandbox functionality.

This means that it can only affect and see files in a subdirectory under ~/Library/Containers. The .azw files are in ~/Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/My Kindle Content

This directory is shown in the Kindle app in Preferences->General as the value of Content Folder and it appears that this can be changed there.
