How to back up Firewall settings?

I need to wipe my C: drive. How do I back up all my Comodo Firewall settings? Thx

Hi racecardriver,
Export your current active configuration to a .cfgx file and store this file externally.
After re-installation, import your configuration from the previously stored .cfgx file and activate.

Kind regards.
