How to Change Partition Size in Windows 8 with Partition Tools?

My Windows 8 hard drive has been partitioned into two drives, partition C 30GB, and partition D 220GB. Because of the installment of operating system in partition C, it hardly has free space to install other programs. Is there a solution that can extend partition C without moving any files? Because if some of the programs were moved to other place, they will not work.

Have you ever come across the same situation? This problem is annoying, because it prevent you from updating or installing some other programs. What's worse, the operation speed of the computer becomes slowly simultaneously.

Even though built-in Disk Management in Windows 8 has the functions of extend and shrink volume, but the feature of extend volume can not be used unless there is an unallocated space just right behind the partition you want to extend. Therefore, you can not extend partition C by shrinking partition D, since it comes out that the unallocated space locates right besides partition D instead of partition C. However, you can reach your goal by deleting partition D, which will cost you a lot of time to backup and restore files on partition D if there are so much data.
