A TXT file is a simple text document that contains plain text without any formatting.

It is widely used for its versatility and compatibility, as it can be created and opened on any operating system using basic text editors like Notepad on Windows, TextEdit on macOS, or even command-line tools.

TXT files are lightweight and ideal for storing notes, code, or other text-based data.

With the file extension .txt, these files are easily shareable and readable across various platforms, making them a universal format for plain text storage.
