What is a COK file?

This COK file acts as a game save file. It uses a ZIP archive format to store your city design and game progress.
Alternative Use (Thermomix Recipe File):
In some cases, a COK file holds a recipe for Thermomix devices. This type is connected with Cook Expert and may be seen as a Cookidoo recipe file. For extra details, visit Magimix.
Additional Use (Website Cookie Data File):
A few COK files contain cookie information managed by browsers like Google Chrome. For more about Chrome cookie handling, see Chrome.
  • Use Cities: Skylines to open game save COK files.
  • For recipe COK files, use the official Thermomix/Cook Expert app.
  • Cookie COK files are managed internally by your browser.
