azw
What is a .azw file?
application/vnd.amazon.ebook
AZW is an early Amazon Kindle e-book container derived from the Palm Database and Mobipocket family. Unencrypted files combine a PalmDB record table with text, metadata, and optional image records; commercial AZW books may carry DRM, which a test fixture should not include or imply it can remove.
How to use a .azw file
Use a small unencrypted example .azw file to test container and record-table detection, metadata extraction, graceful handling of unsupported compression or DRM flags, and validation against documented sample text rather than a filename-only success check.
