Navigates to the named option set. file. Click [...] to display a file selection dialog.  

Action 

You have three choices for how you apply values: Overwrite, Replace, or Preserve.
Overwrite replaces the current configuration with the values from the option set entirely. That is, the values from the option set overwrite the current configuration and all other option values are set to their defaults. You get exactly the same configuration as when the option set was originally saved.
Replace writes all the values from the option set to the current configuration, but no other values are changed. The values in the option set replace the current values, giving priority to the option set.
Preserve writes only the values from the option set that are not already set in the active configuration. If the active configuration changed any of the values from their default values, they are not changed. This gives priority to the configuration.
