TXT

Plain Text File Format

A TXT (Plain Text File) is a simple and widely used file format that stores unformatted text, making it universally readable across different platforms and devices. It can be opened and edited by basic text editors like Notepad, TextEdit, and more advanced tools like Notepad++, VS Code, or even integrated development environments (IDEs). The format contains only raw text characters, without any embedded formatting, images, or metadata, though it supports basic line breaks and encoding standards like ASCII or UTF-8 for multilingual text.

AZW3

Kindle eBook format

AZW3 is an e-book file format developed by Amazon for use on Kindle devices and apps. It is supported by Kindle devices, the Kindle app, and tools like Calibre for conversion and management. The format is based on the MOBI structure but includes advanced features like enhanced typography, embedded fonts, and support for HTML5 and CSS3 for richer formatting and interactivity.
