How to move free space from one partition to another?
I got 2 partitions on my Dell computer. C drive which had 50 GB and D drive which had the rest of my 500GB. Now the C drive is filled up, so i tried to shrink the D drive to extend the C drive, but it didn't let me extend the C drive unless I delete the D drive. Is there a way of move the free space?"

Some Windows users did not partition their disks in a reasonable way at first. As times go by, you might find your C drive is out of space. To get more free space on this drive, most of people tried to delete the old or unnecessary files. But this could not solve the problem from the source.
Actually, there are some ways to move some free space from other drive to the C drive indeed. If there are some adjacent unallocated space after the C drive or the partition you want to extend, you can extend the C drive using Disk Management in Windows 7. But if there is no adjacent unallocated space, the "Extend Volume" would be grayed out. And you can refer to the following content to see how to allocate free space to C drive easily.
Except Windows built-in tool Disk Management, you can use some third-party software to move free space from other partition to system partition.
