A workbook file is a part of every scenario. It is saved as a separate file. When the workbook is created, it receives the same name as the scenario, with an "STK Scenario WB" file extension. The scenario workbook contains information about the current layout of the STK workspace. When the scenario is reopened, if a workbook file is present, the layout of the windows and toolbars in the workspace will match the layout that was set when the scenario was created. This enables you to configure the workspace optimally for each scenario and to allow other users to benefit from that configuration.
Note: If the workbook is not found in the user config directory, it is loaded from the <STK install folder>\prefs folder. STK will continue to load the installed version until you save the scenario.
