The primary divergence is with proprietary formats. Only the Kindle can access Amazon’s Kindle bookstore and read its AZW file format. This bookstore contains the overwhelming majority of Kindle’s retail book inventory, with more than 300,000 titles. In this scheme, the AZW files are protected by Digital Rights Management (DRM). Because DRM prevents a user from making a copy of a file or playing on an unauthorized device, these books are technically licensed rather than purchased.

We provide several program to remove ebook DRM:
