You can use Disk Management to add space to an existing volume, extending it into empty space on the drive, but only if the empty space doesn't have a volume on it (it's unallocated) and comes immediately after the volume you want to extend, with no other volumes in-between, as shown in the following image. Applies To: Windows 10, Windows 8.1, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
