Remarks
IStorage::RenameElement renames the specified substorage or stream in this storage object. An element in a storage object cannot be renamed while it is open. The rename operation is subject to committing the changes if the storage is open in transacted mode.
The IStorage::RenameElement method is not guaranteed to work in low memory with storage objects open in transacted mode. It may work in direct mode.
