Clicking View > Catalog Browser (or
on the View toolbar) will show the Catalog Browser panel.

This panel lists all data sources, report sets, and styles belonging to the current catalog file (.cat) in the tabs: Data, Report Sets, and Styles. This is a useful interface which simplifies the work of report design and the management of the actual resources you use.
Data tab
In this tab, you can manage data sources and their contents used by the catalog.
Report Sets tab
Manage your report sets in Folder view. You can divide them up into different types. In this way, you can manage them just like processing files in a file system. You can add, open, delete, move, rename and search for items. For details, see Report Set Manager.
Styles tab
From the Styles tab, you can create and edit styles. For details, see XSD styles.
