The RAM Manager creates backup files of all RAM models before link operations begin. This backup is redundant since the original model is closed before the ISM link tool is activated and will still exist in its last saved state. If a serious error does occur during link execution, the next time that RAM model is loaded and an ISM link menu item is selected, a dialog will be displayed with showing the full path to the created backup file. The name of the file also gives the date and time the error occurred.
