You can delete shelves and files from shelves that are no longer used. Before deleting a shared shelf, make sure users do not need access to it. Deleting a shelf also deletes any files stored in it.
1. Choose View > Shelves.
The Shelves window opens.
2. Select a shelf or file and click Delete.
You are prompted to confirm the deletion.
3. Click Yes.
The shelf or file is deleted.
