To delete assets in your catalog, first locate them in the Search tab, or if they are unlinked items, in the Unlinked Catalog Items view of the Browse tab. You cannot delete assets from the Catalog view of the Browse tab.
The child assets of a deleted asset are handled as follows:
Deleting a catalog folder containing a child folder moves the child folder to the top-level of the catalog hierarchy.
In all other circumstances, the child assets are turned into unlinked catalog items, retaining their hierarchal relationships to each other.
Consider a situation in which you want to delete the Entertainment Category, which exists in the following hierarchy in Catalog view:
Entertainment Category
TV Category
HDTVs Product
Generic TV Brand 23" Widescreen SKU
Using the Search tab, you locate the Entertainment Category and delete it. This action turns TV Category into an unlinked catalog item and removes the TV Category, HDTVs Product and Generic TV Brand 23” Widescreen SKU from Catalog view; you need to open Unlinked Catalog Items view to see the TV Category and the assets nested in it. In that view, you can delete the remaining assets or provide a new parent to TV Category, which moves all assets back into the catalog and makes them visible again in Catalog view.
