MapForce uses a Multiple Document Interface (MDI). Each mapping file you open in MapForce has a separate window. This enables you to work with multiple mapping windows and arrange or resize them in various ways inside the main (parent) MapForce window. You can also arrange all open windows using the standard Windows layouts: Tile Horizontally, Tile Vertically, Cascade. When multiple mappings are open in MapForce, you can quickly switch between them using the tabs displayed in the lower part of the Mapping pane (see screenshot below).
You can access Window management options using the menu command Window | Windows. The Windows dialog box allows you to perform various actions including activating, saving, closing, or minimizing open mapping windows. To select multiple windows in the Windows dialog box, click the required entries while holding the Ctrl key pressed.
