Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
How do I open an AZW file on Windows or Mac?
You can view these files using the official Kindle for PC or Kindle for Mac software provided by Amazon. Alternatively, the open-source e-book management tool Calibre can open and view .azw files, provided they are not locked by DRM (Digital Rights Management).
Can I convert an AZW file to PDF or EPUB?
Yes, you can convert .azw files using software like Calibre or various online conversion tools. However, if the file is purchased from Amazon, it is likely protected by DRM, which prevents conversion to other formats like PDF or EPUB without removing the protection first.
What is the difference between AZW and AZW3?
The original .azw format is based on the older MOBI standard, while AZW3 (also known as Kindle Format 8) supports advanced formatting like HTML5 and CSS3. While both use similar extensions, AZW3 allows for richer layouts and better font support.
How do I read AZW files on Android or iPhone?
The easiest method is to install the free Amazon Kindle app from the App Store or Google Play. You can send the .azw file to your device via the Send to Kindle service or simply sync your Amazon library if the book was purchased officially.
What MIME type is used for AZW files?
When configuring servers or identifying file headers, the standard media type is application/vnd.amazon.ebook. You can find more technical details about this configuration at mime-type.com.
Why can't I open my AZW file in a generic e-reader?
Most non-Amazon e-readers rely on the .epub standard, whereas .azw is a proprietary format specific to the Kindle ecosystem. Unless the device explicitly supports Amazon formats, you will need to convert the file to EPUB first.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
