What are Text Files? Definition and list of extensions

A text type file is one that stores plain text information, that is, it does not contain control characters, it only contains printable characters such as letters, numbers and symbols, usually from the ASCII character set. The ASCII standard allows text files to be freely exchanged and readable between platforms such as Unix, Macintosh, Microsoft Windows, DOS.

A text file can be created or edited using a text editor and can usually be imported into any plain word processor such as Notepad.

Text file extensions allow the operating system to identify plain text documents. The most used text file extensions are: .txt (Microsoft Windows) and .mime (MAC OS X, Linux).
