File Extensions FNT and FON File Formats SUMMARY: Explains .FNT and .FON fonts and why they differ from TrueType fonts.   The FNT and FON file formats usually refer to older Windows raster and vector fonts. Unlike TrueType font files (.TTF extension) that can be resized to virtually any small or large size, the older FNT and FON files are limited to specific sizes. Also, they may not look exactly the same onscreen and on paper. Windows users: NOTE that unless you have configured your computer with the file extension viewing tweak, it is possible that a filename that looks like it ends with ".fnt" or ".fon", especially one attached to an e-mail message, actually has a hidden OTHER extension, meaning that if you double-click the file, it may actually run a computer virus!   Add: Del.icio.us | Digg | Furl | My Yahoo!   Discuss This Tip Print This Tip Get E-Mail When New Tips are Online Return to the File Extensions page.
