The delimiter string to use when listing objects.
If this property is non-empty when ListObjects or ListVersions is called, any objects (or object versions) whose names contain the same string between the specified ObjectPrefix and the first occurrence of the specified delimiter that follow will be rolled up into a "common prefix" element, which is returned in place of the individual objects themselves.
The PrefixList event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the class will also populate the PrefixCount and Prefix[i] configuration settings
Object Hierarchy Traversal
By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:
|ObjectPrefix Value||ObjectDelimiter Value||Objects Returned||Prefixes Returned|
This property is not available at design time.
