Method 1: Using Disk Management to Extend Volume Server 2022


Extending volume will only show up for drives under the following terms and conditions:

  • The target drive is NTFS, or non fat32 c drive (cannot go with fat32 c drives)
  • There is unallocated space on the right side
  • The unallocated space is on the primary partition plan instead of logical drive plan (The unallocated space is shrunk from primary partitions instead of logical partitions for instance.)
  • The c drive is on a drive on a GPT disk, or MBR disk less than 2TB

Windows come with a native Disk Management tool that has a graphic interface. For this reason, it becomes easy to use for a majority of users. You can extend NTFS using Disk Management using the suitable adjacent unallocated space. It means that before proceeding with an extension of the C drive, you must delete the D drive.

To resolve this purpose, you must keep in mind that the partition that has to be removed and then extended must be of the same type. If both partitions C and D are not using the same partition type Primary or Logical, extend volume will not be enabled.

For example, if the D drive was set to Primary, you can remove it smoothly to enable the extend volume for c drive which is the primary partition. Or you need to change the D drive to primary partition at first before the deletion.

Steps to Use:

Step 1: Start by tapping on ‘Win + X ’ using your keyboard, and from the list, tap on ‘Disk management

Step 3: Now, on the C drive, make a right tap and then make a selection of ‘Extend Volume’ From the ‘Extend Volume Wizard pop-up window,’ follow the steps mentioned on the screen to finish the extending.
