FontLab FogLamp turns Fontographer 3.5-4.1 database files (.fog) into FontLab VFB files (.vfb) that are compatible with TypeTool, TransType, FontLab (Studio) and AsiaFont Studio.
With this solution, you can make OpenType fonts using Fontographer or salvage your old .fog projects.
FogLamp sheds some light onto the opaque Fontographer file format.
