The file is used as a resource associated with legacy 16-bit software. Its resource data identifies the location of a TTF font that the executable or DLL can use.
A .for file is therefore not normally a font file that can be installed or viewed on its own. The resource forms part of the 16-bit EXE or DLL application's supporting data.
This is a legacy format associated with 16-bit software and is uncommon on current platforms.
A .for file normally requires a resource editor or development tool that supports the 16-bit executable or DLL in which the resource is used. It will not usually open in a standard font viewer because it contains a font path rather than the TTF font data.
On a modern operating system, the associated 16-bit application or resource tool may require a compatible legacy Windows environment, virtual machine, or emulator.
There is generally no useful standalone conversion for a .for file. It is a resource that references a TTF font, not a font format containing glyph data.
To migrate the application, locate the referenced TTF file and use that font separately, then recreate the resource with tooling appropriate for the target application's platform.
