The "Extend Partition" function of another program called AOMEI Partition Assistant can also help with this problem. However, I'd like to recommend you to try its "Merge Partitions" function for its more easy and powerful. It can not only merge two partitions (the two partitions must be next to each other; you can merge data partition into system partition, but cannot merge system partition into data partition), but also merge partition with unallocated space (the unallocated space can be located on any place of the hard drive). So, with this function, your problem can be solved easily.
