Need to resize partition?

Have you ever encounter a problem that C drive is full, while D drive is almost empty? Or there is some unallocated space on your disk, and you don’t know how to take advantage of it?

If the answer is “Yes”. It is necessary to get a piece of partition resizing software for Windows. And some people might use the Windows built-in Disk Management to manage their partition and disk. It works well in some simple operations.

But Disk Management is not recommended here to resize partitions in Windows 10, 8, 7 because it has some disadvantages making it not so flexible and convenient. For example, it can’t extend a partition with non-adjacent unallocated space. And in most conditions, the unallocated space is not closed to the partition you want to extend.
