You can use the Exit Script script step within the triggered script to return True or False.

  • The script will run even if the file itself remains open, for example if it is referenced by another file with open windows. The closing script will be performed each time a window of the specified file is closed.
  • If the script executed by the OnWindowClose script trigger returns a False value, then the file will not close.
