What is the difference between .aw and .azw3?

Description: The AW file type, standing for Answer Wizard File, is associated primarily with Microsoft Office applications, particularly with Microsoft Word and its integrated help system. AW files are designed to store indexes and data used by the Answer Wizard feature, enabling users to search for and receive help or answers to questions about using Microsoft Office programs. The Answer Wizard offers a more intuitive way for users to find assistance by allowing them to type questions in natural language, after which it searches through its database of AW files to provide relevant help.; An AZW3 file is an eBook created in the Kindle Format 8 (KF8), Amazon's successor to the .AZW format. It supports newer features such as HTML5 and CSS3 support as well as many other formatting capabilities. AZW3 files often include DRM protection and are used as the download format for many Amazon eBooks.
