Importing and Exporting Preferences
You can import and export the preference settings as COMSOL preference files (*.prefs). In the Preferences window, click Import at the bottom of the dialog to choose a COMSOL preference file to import from the file chooser window that opens. Then click Open to import and use the preferences from the chosen file. Click Export at the bottom of the window to choose a COMSOL preference file to export the preference to from the file chooser window that opens. Then click Save to save the preferences in the specified file.
By default, most preference settings are migrated from the previous COMSOL Multiphysics version the first time that you start an instance of a new version of COMSOL Multiphysics. See Preference Migration for more information.
