Final answer:
To make use of the new space after splitting a partition using the shrink volume feature, the technician must allocate the new space to a new partition or extend an existing partition.
Step-by-step explanation:
After using the shrink volume feature of the disk management utility to split the partition, the technician must allocate the new space to a new partition or extend an existing partition to use the new space.
To allocate the new space to a new partition, the technician can create a new simple volume and assign a drive letter to it.
To extend an existing partition, the technician can right-click on the partition and select the 'Extend Volume' option, then follow the on-screen instructions to allocate the new space.
