You can delete all document links with one action using the Delete document links process. Before deleting any links, you are advised to check the existence of any links on the Where used form. You might want to use the Export list option in the Reporting menu to export the contents of the List tab of the Where used form. The exported list will enable you to restore the links later, if necessary.
When the last document link is deleted, the registration itself can be deleted automatically. To have the registration deleted automatically, select the Delete document registration when deleting last document link check box.If some users are allowed to link documents, but are not allowed to manage documents, it is recommended to leave the Delete document registration when deleting last document link check box empty.
