If You Have Reduced D Drive but Can’t Extend C Drive, Try This Way
Question: C drive is nearly full while D drive has more than 100GB free space, so I planned to shrink D to enlarge C. Nevertheless, I have reduced D drive but still can’t extend C drive in Windows 7 Disk Management. Why?
Answer: that is because space got from D drive is not right contiguous to drive C. Users who are quite familiar with Windows Disk Management know "Shrink Volume" feature can only make an unallocated or free space after its source partition, and the very space can only be used to create a new drive or extend the source partition itself. And "Extend Volume" enlarges a partition only with contiguous unallocated or free space on the right side. That’s why you can’t reduce D drive to extend C drive in Windows 7 Disk Management.
Solution: currently, some third party partitioning tools can help complete these operations, among which MiniTool Partition Wizard is outstanding. It is a piece of free but mighty partitioning software. To extend C drive can be realized in few clicks even if there is no unallocated space right neighboring to it. Next, we will show users detailed steps.
