Command entry: cuiYou open a CUIx, CUI, MNS, or MNU file to import or export user interface data. When you open CUI, MNU, or MNS files, they are not converted automatically to a CUIx file format until you save the new file that is created. The original CUI, MNU, or MNS file is not modified.

You open a CUIx or legacy customization file in the left pane to transfer data. When you enter cuiexport at the Command prompt, the main CUIx file is displayed in the left pane. You open another CUIx or legacy customization file in the right pane to transfer data.
