If you start Type Explorer without a VOB context or click in the main Type Explorer window, this window opens.
Type objects are stored in VOBs. Each VOB has its own set of type objects, although they may be copies of a global type object in an administrative VOB. Use this window to select the VOB that contains the types to explore.
Select a VOB in the list and click OK. In the Type Explorer window, folders are displayed; they contain the type objects for the types stored in the VOB that you are accessing.
