A .TXT file is a type of text file that contains only plain text, without any formatting. Creating a .TXT file is easy - all you need is a simple text editor like Notepad or TextEdit. To create a new .TXT file, simply open your text editor and begin typing. When you're finished, save the file with the ".txt" extension. That's all there is to it! .TXT files are often used for storing data that needs to be read by humans or by other programs. For example, many software applications use .TXT files for configuration settings or for lists of data (such as lists of filenames or usernames). When creating a .TXT file, be sure to use the correct file extension, or your file may not be readable by other applications.
