Use Diskpart to Extend Partition

Diskpart, a highly flexible command-line utility, allows users to oversee disk partitions on Windows systems. Once you've confirmed that Diskpart is indeed the ideal solution for your task, let's delve into the systematic procedure to use Diskpart to extend partition with unallocated space:

Step 1: Use the Windows search bar to look for Command Prompt. Then, click "Run as administrator" to launch it with admin privileges. Run the diskpart command within the Command Prompt to access the Diskpart utility.

Step 2: Type list disk and press "Enter" to access the list of available disks on your system. Next, run the select disk X command with "X" denoting the number of the disk that is your target. Then, run the command list partition to access the available partitions on the targeted disk.

Step 3: The following command you need to run is select partition Y, with "Y" representing the number of the partition you want to extend. To extend the partition into unallocated space (if available), use the command extend size = N. Once you have successfully extended the partition, type exit and press "Enter".

After this, you can go to This PC or Disk Management and check if your target drive has been extended successfully.
