Can I save my data before Force Quitting an Application? When an application is not responding I force Quit and Restart it.

But, is there a way in which I can save my data before quitting? Is there anything I can do to confirm that the application is really dead?
Unfortunately when an application is not responding, it is generally not possible to rescue any of the data. The exception to this would be applications that save a recovery file at regular intervals e.g. Microsoft Office suite of applications.

Your options are either to wait and hope that the application responds or the Force Quit.
