Move unallocated space

How to move unallocated space

Unallocated space can be used for extending partitions when low disk space alert happens to your server disk, but in the default Windows Disk Management tool, the Extend Volume option will still be grayed out even when unallocated space is available on the same disk, why? Because it's not at the right position, Disk Management requires continuous unallocated space to the partition you want to resize will it activate the Extend Volumefunction.

But the unallocated space we shrank from large sized partition in most of the cases is not always behind the target partition we intend to extend unless we creating unallocated space by deleting the continuous partition, which is the last thing we would do on Server disks.

Is there any methods we can move unallocated space without touching the rest of data?
