Re: “Delete Catalog" command in “browse catalogs"?

That could be a documentation error, or you could be getting confused with the Browse Database command which shows a list of catalogs on the server (if you're using CatDV with the CatDV Server). But you're right, you can just delete catalog files from the Finder.

By the way, we long since standardised on the American spelling of catalog because "cataloguing" just looks too weird!
