Assets can be deleted at any time if you no longer need them or they're old and outdated. You must have permission to delete assets in an asset group in order to remove assets from your site.
Delete individual assets by clicking the trash can Delete icon on an asset's thumbnail in search results or on the Asset Details page. Assets can also be deleted in a batch using the Selection panel.
Deleted assets are placed in the Pending Delete queue on the Admin dashboard. As a Acquia DAM (Widen) admin, you can review and permanently delete or restore assets to the site from that queue. Asset groups are not deleted when assets are deleted.
