Usage differences for the "du" action
The "du" action has usage differences between FileStore (NS3) and ObjectStore (NS4).
There are no explicit differences in usage with this action.
However, with the ObjectStore (NS4) methodology in place, characters that were specifically reserved for use as file name and/or path separators in FileStore (NS3), are now supported for use in object names (“/” and “.”). Take this into consideration when targeting objects using this call in ObjectStore (and be sure to include these characters, as necessary to target the desired object).
