What does the extension .txt represent?

The extension .txt represents a basic text file without formatting. This type of file is designed to contain plain text, meaning it does not include any special formatting such as bold, italics, or different fonts that are commonly found in word processing documents. Consequently, a .txt file can be opened and edited using simple text editors like Notepad or TextEdit, and it is universally compatible across different operating systems and text processing applications.

This simplicity and lack of formatting make .txt files ideal for storing plain data, such as notes or code snippets, where the integrity of the text is more important than its appearance. They are efficient in terms of file size and are widely used for a variety of applications, from programming scripts to simple text documentation.
