Posted by on .

Books downloaded from the Amazon Kindle Store come in .azw format. This format was developed by Amazon from the open source .mobi format. The two formats are basically the same except that Amazon added digital rights management (DRM) to the .azw files. As an Amazon-owned format, azw is not that open compared to the industry standard ePub format, which leads to that many reading devices and apps can't read your azw books. So here comes the demand to convert Kindle AZW to ePub, PDF or TXT, but how to convert azw books to epub, pdf or txt books for reading on Sony e-reader and other devices?

The items were already downloaded.  The problem is that I can't get to the directory  of my kindle content other than through Windows.  When I click on the kindle directory in Windows, there's nothing there.
