The TYPES file format is a plain text configuration file created as part of the TeX typesetting system developed by Donald Knuth. It is primarily used for defining font properties, character mapping, and layout parameters within legacy LaTeX and TeX distributions. As a text-based format containing no executable code, it is considered safe for general use, though it has largely been superseded by modern font management systems and digital publication standards.
