Windows Font Library (.fon)

The FON file extension is associated with an old font format from early Windows versions. As an executable-like file labeled as FON, it serves as a container for font collections, which are stored in the FNT format. Despite being outdated and replaced by scalable TrueType fonts, FON files remain supported for backward compatibility and are accessible through the Windows Font Viewer.
