But, if there's no unallocated space, if you allocated all the space into partitions, command line is not that good to use. It has obvious advantage at the first using of a new disk, say, an empty disk, after initialization, it's a large size disk with no partition on it, first command on partition is Shrink partition, then you can make partitions with the unallocated space, create partition is very easy at that period of time. It will fail if you try to extend system partition by this command tool, because Diskpart only works for other logical partitionĪlthough there're many partition utilities, some of which are free tool, diskpart is the often used tool for many server users to extend data partition when they have unallocated space followd, the command line provided by the original system makes partition operations much faster than any software with graphical interface. Disk management utility built in Windows doesn’t allow to extend system reserved partition. The best solution is to extend the system reserved partition to expand the free space.
