ArcCatalog (Fig. 11) is where GIS data can be searched for, previewed,
and managed. Also, some ArcToolbox tasks can be performed and visualized, but
not overlaid with other layers like in ArcMap. Since ArcGIS version 10.0, a
more compact version of ArcCatalog can also be accessed directly in ArcMap.
ArcCatalog should be used when geographic data are added, moved, or deleted
from GIS in order to avoid losing important file extensions (e.g. the
geographic reference, see section 3.1 for more information). To open
ArcCatalog: Start menu > All programs
> ArcGIS > ArcCatalog 10.1.
