Move Unallocated Space to the Left, Right or End of A Drive Easily

Why You Need to Move Unallocated Space

There are many partitions on a disk, like C, D, E drives. There are also some unallocated space on the disk shown as "*" and marked as unallocated. The unallocated space is the space that hasn't been put into use. You cannot use it until you use the unallocated space to create a new partition or add the space to other drives.

When the unallocated space is right behind the partition, right-click on the c drive, and choose Extend Volume to enlarge the c drive space. When the unallocated space is not right behind the partition, you are unable to extend a partition with the help of Disk Management.

The free built-in utility just allows you to resize windows partition with unallocated space just behind the partition you want to expand. Otherwise, you might be caught in "extend volume greyed out" error. Many users are suffering from this issue when they are trying to extend C drive
