Use this procedure to add an existing tool catalog to your catalog library.
Adding a tool catalog to a catalog library does not physically move or copy any files. Instead, a pointer to the catalog’s location is added to the catalog library. If you add a tool catalog that resides on another computer, and then a tool in that catalog is updated, you always reference the latest version of the tool in the catalog library.
Before beginning this procedure, it is a good idea to verify that the tool catalog you will be adding does exist in the location you will be specifying.
Tool catalog files typically have the extension .atc.
