below to resize disk volume on Windows 2012 Disk Management:
Firstly, you should check if there is unallocated space on the same hard disk. If there is
no unallocated space, you need to open Disk Management and select a volume that has free
space. Then, you can right click this volume and select "Shrink Volume"
option.

selected volume. You need to move the unallocated space close to the volume you want to
extend. Since Disk Management cannot move a partition, you need to delete the volume between
the unallocated space and the volume you want to extend.

option so as to add the unallocated space to the selected volume.
