The TXT file format is a plain text format that is commonly used for storing and sharing text or data files. It is an ideal format for storing text and for sharing information, as it is a very basic, platform-independent file format. TXT files can be opened with any text editing program, such as Notepad or WordPad on Windows, and TextEdit on Macs. They can also be opened with any web browser. TXT files are human-readable and can contain plain text, simple text formatting, and hyperlinks. TXT files are mainly used to store notes, source code, and other small bits of information. They are also used to store HTML files, as they can easily be converted to HTML format. TXT files are often used to store configuration settings, readme files (text files included with software that describe how to use the program), and data files. TXT files have the advantage of being small and lightweight, and can be quickly opened and read. However, they do not support rich text formatting, which means that formatting such as italics, bolding, and fonts cannot be used. Additionally, TXT files cannot store images or other types of multimedia.
