A TXT file is a standard text document that contains unformatted text. It is one of the most basic and universally supported file formats, designed to store sequences of characters without any specific formatting, such as bolding, italics, or font styles. TXT files are typically encoded using ASCII, UTF-8, or other character encoding schemes. They are widely used for storing simple notes, configuration files, source code, log files, and any other data that needs to be represented as plain text. Because of their simplicity, TXT files are highly portable and can be opened and edited by virtually any text editor or word processor on any operating system. They are often used as a lowest-common-denominator format for exchanging text-based information between different applications and platforms. While TXT files lack advanced formatting capabilities, their simplicity and compatibility make them an essential part of digital communication and data storage.
