What is an AZW4 file?
AZW4 is a proprietary format designated by Amazon as 'Print Replica', specifically designed for textbooks and PDFs where page layout preservation is critical. Technically, an AZW4 file consists of a standard PDF file wrapped within a Palm Database (PDB) container, often adding a layer of Amazon's DRM. Unlike reflowable AZW3 files, AZW4 maintains static pagination and formatting, effectively acting as a wrapper that allows PDF content to interact with the Kindle ecosystem's annotation and highlighting features.
How to open an AZW4 file
AZW4 files are intended for use on larger screens and are best viewed using the Kindle App for PC and Mac, or Fire Tablets; they are often incompatible with older E Ink Kindles due to display limitations. If the file is DRM-free, users can extract the underlying PDF using software like Calibre or specific Python scripts designed to unwrap the PDB container.

What is an RTF file?
The Rich Text Format (RTF) is a proprietary document file format with published specifications developed by Microsoft Corporation in 1987 for cross-platform document interchange. It encodes formatted text and graphics using 7-bit ASCII characters, utilizing a structure of control words, control symbols, and groups to define formatting properties such as bolding, italics, and fonts. Unlike binary formats, RTF is human-readable and was designed to facilitate interoperability between different word processing software and operating systems before the standardization of XML-based formats.
How to open an RTF file
Due to its design as an interchange format, RTF possesses native support across almost all major operating systems without requiring third-party installation. Microsoft Windows opens RTF files natively with WordPad or Microsoft Word, while macOS utilizes TextEdit. For Linux users or cross-platform consistency, LibreOffice Writer and Apache OpenOffice provide robust handling of the format's styling attributes.
