What is a .kmz file?
A .kmz file is a Keyhole Markup Language (Container). This is a code, script or executable format.
How to open a .kmz file
- VS Code opens and highlights nearly every text-based code format.
- Never run a script you didn't write or trust.
The registry records this extension against Keyhole Markup Language (Container), so software from that family is the most likely match.
How to convert a .kmz file
- Text-based code needs no conversion — just save with a different extension if a tool insists.
