Open FOT File

The FOT extension is used specifically for Font Resource (FOT) files, which is used in Microsoft (MS) Windows based operating systems.

FOT, in this case, is a proprietary binary format of the executable type similar to the old .NE (new executable) that was used with Windows 3.x. The initial purpose of the FOT format was to interface or link to TrueType Font (TTF) files that could not be used directly by Windows 3.x. Then, in later versions of MS Windows (up to Windows XP), FOT files became compatible and accessible through calls to Windows API functions.

A FOT file basically contains references to the TTF font files to be installed. This being the case, FOT files is used in the installation process of "embedded fonts" in Windows and allow such fonts to be transferred between computers. Therefore, it is necessary that, for a FOT file to work correctly, the associated TTF files must remain in their initial location, if the latter change their location, the reference will give an error.

In newer versions of Windows, FOT files lose their usefulness, as they are temporary system files created for compatibility purposes. It should be noted that no application is associated with this type of file, therefore its manual opening is not recommended.
