Plain Text
Example: "Plain text is the most efficient way to store textual data."
Plain text is another name for unformatted text. Unlike rich text, plain text does not support italics, underlining, bold characters, fonts, or font sizes. Since plain text documents do not contain any text formatting information, they take up less disk space than rich text documents. Therefore, plain text is commonly used for log files and other types of text documents that don't require formatted text.
