 Remarks
            Prefixes can be used to separate a bucket into different groupings of keys. 
            You can think of using prefix to make groups in the same way you'd use 
            a folder in a file system.) You can use prefix with delimiter to roll 
            up numerous objects into a single result under CommonPrefixes.
