Loading and using a partial CUIx file allows you to create and modify most user interface elements in a separate CUIx file without changing the customization in the main CUIx file.
You can create a partial CUIx file to store your user interface customization with the Transfer tab of the Customize User Interface (CUI) Editor. After a CUIx file is created, it can be loaded or unloaded from the Customize tab in the Customize User Interface (CUI) Editor. You can also load and unload CUIx files with the CUILOAD and CUIUNLOAD commands from the Command prompt. The order in which partial CUIx files appear under the Partial Customization Files node in the Customize User Interface (CUI) Editor determines the order they are loaded in to the program. You can rearrange the hierarchy of the items to change the load order.
Commands and user interface elements can be added to the main CUIX file or a partial CUIx file that is loaded with the main CUIx file, but not the enterprise CUIx file. Before adding commands to a partial CUIx file, the partial CUIx file must be set as the working CUIx from the Customization Files drop-down list on the Customize tab of the Customize User Interface (CUI) Editor.
When a partial CUIx file is loaded, any workspaces defined in the file cannot be used. However, you could transfer a workspace defined in a partial CUIx file to the main CUIx file and then set it current.
