You can use Disk Management to add space to an existing volume, extending it into empty space on the drive, but only if the empty space doesn’t have a volume on it (it’s unallocated) and comes immediately after the volume you want to extend, with no other volumes in-between, as shown in the following image. In this article, you will learn how to extend System Drive Partition on Windows. Please see how to fix the “Error when importing an OVA file to AWS: Client error – saved empty is empty“.
The volume to extend also must be formatted with the NTFS or ReFS file systems. Simply by adding a logical partition to increase the size of Drive C. I will be discussing how this is achieved in a later article.
