What is a FOG file?

FOG files mostly belong to Fontographer. FOG files can mean one of two things. The most common use is as a Fontographer font file. These files store font data such as glyph shapes and layout details. They are used with font editing software like Fontographer or the open source FontForge.
In other cases, a FOG file is a game level file. For example, some files from Tomb Raider II use this extension to hold level design details. Such files are read by game engines or level editors.
  • Check which context your file comes from before opening it.
  • Use dedicated software for each file type.
  • Always backup your file before making changes.
  • FilExt.com note: For more info on the font file use case, visit the Fontographer page.

    How to open a FOG file

    You need a suitable software like Fontographer to open a FOG file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your FOG file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a FOG file directly in the browser:. Just drag the file onto this browser window and drop it.
