You must have system administrator or superuser privileges to delete a storage area.
To delete a storage area:
Connect to the repository.
Navigate to Administration > Storage Management > Storage.
The Storage list page appears.
Select the correct object (storage area, location, mount point, or plug-in) to delete and then select File > Delete.
Click OK to delete the storage area.
The object is deleted and the Storage list page appears.
If you deleted a file store, the associated location object is not automatically deleted; if you want to remove it from the repository, you must delete it separately.
