Text file extension list

File extensions used for various plain text and ASCII file types.

Text file is a type of computer file, which often stores plain text information in ASCII format. ASCII (American Standard Code for Information Interchange) is a character-encoding scheme based on the ordering of the English alphabet. The ASCII standard allows ASCII-only text files to be freely interchanged and readable on Unix, Macintosh, Microsoft Windows, DOS, or other platforms. ASCII codes represent text in computers, communications and other devices that use text.

Modern character-encoding schemes, which support many more characters than did the original, are based on ASCII. Text files have a plethora of file suffixes, but most used file extension which identify simple text is txt or text (Microsoft Windows) and the MIME type used for it is "text/plain" (MAC OS X, Linux).

Text files can be simply opened and edited in many of plain text editors (Notepad, Notepad++ and many others).
