Extend volume for C drive

The following operations are applicable to computers with SSD only. If your computer has both SSD and HDD, you cannot extend volume in C drive by merging D drive with C drive. To ensure that your C drive has sufficient space, clear data in C drive regularly and install software in other drives.

If you want to extend space in C drive, merge C drive and D drive, and then reallocate disk partition for both drives. To do this, perform the following:

  1. Back up data in D drive to C drive or an external storage device such as a portable hard drive.

    Back up data before merging both drives to avoid data loss.

  2. Right-click the Windows icon on the desktop and click Disk Management.
  3. Right-click on Data (D:) and select Delete Volume, and click Yes. An unallocated partition will be displayed. Right-click Windows (C:) and select Extend volume. Extend C drive by following the onscreen instructions. Now, data that originally in D drive has been combined to C drive.

  1. Right-click Windows (C:) and select Shrink Volume. Enter desired volume size for the new partition in Enter the amount of space to shrink in MB. Right-click any blank area on Unallocated and select New Simple Volume, and then create a new partition by completing the onscreen instructions. Assign the letter D for the new drive.
