Frequently asked questions
What is a .azw file?
Amazon's proprietary ebook format for the Kindle platform, based on Mobipocket with Amazon-specific extensions.
Can I edit a .azw file?
Partially. .azw files can be edited with the right tool (such as Kindle app), but not with just any text editor.
Does having a .azw extension mean the file is safe?
No single extension can guarantee that. Plain documents are generally low-risk to view. If the format supports macros or embedded scripts, keep them disabled unless you specifically expect and trust them. Always consider where the file came from, not just its name.
