Windows’ built-in disk management tool can be used for some basic operations such as create, delete, format partition and change drive letter etc.

Increase disk space in windows server 2016 with Disk Management

You can increase the C drive free space by right-clicking Windows icon>Disk Management on the bottom left corner. This tool will help you to see all connected disk partition, as well as capacity and free space of each partition. This feature is created for people who insist on using Windows built-in tool. This built-in tool can perform different tasks but previous issues are still there.

The main issue with the built-in disk management tool is you can only extend the drive when the unallocated space is adjacent and at the right side of C: drive with the following steps. (You need to delete the drive next to c drive to create unallocated space next to c. This is the must requirement if you use Disk Management.)

1. Right-click C: drive and select “Extend Volume“ from the options.

2. In the pop-up window, you’ll see Extend Volume Wizard. Click Next,

3. Select the disk and the available space. Now click Next.

4. Review the selected disk and free space, click Finish to proceed

Problems of using Windows’ built-in disk management tool

This operation is only possible when you have adjacent unallocated space at the right side of the drive. If there is no adjacent Unallocated space, the option of extending volume will be greyed out. In this situation, the only option available for you is to delete the D: drive and make it an adjacent unallocated space so that the tool can let you extend the disk volume. And there are some cases where you won't be able the extend the volume even if you have already deleted the D: drive. So not all adjacent Unallocated space can be added to extend D” drive. It was then a problem and it's still the main problem. Some other related issues are,

1. There should be another device to store files.

2. It takes a long time to transfer files.

3. Risk of losing data.

4. After deleting the D drive, applications or services that run from D drive will stop working.

5. In a special situation, You have to delete other volumes together
