How many methods do you know when referring to Windows 10 partition resizing?
Method 1: Resize disk partition with Windows 10 Disk Management
Method 2: Extend partition size by Diskpart command
Method 3: Redistribute disk space with free partition magic software
When you attempt to extend volume by Diskpart command, you may receive message like: "The volume you have selected may not be extended. Please select another volume and try again."
You do not need to feel surprise if you get such kind of message when using Diskpart to extend volume on Windows 10 because it is a common problem for all PC users.
Usually, Diskpart will fail to complete the partition expanding in several situations. This article will introduce different situations in which you are unable to extend volume with Diskpart command on Windows 10.
It is a complex and difficult thing to extend volume with Diskpart command on Windows 10. In order to successfully extend the size of a partition with Diskpart command, existing unallocated space is needed. You cannot extend any volume if there is no unallocated space on the same hard disk on your computer. This page will tell how to make unallocated space on Windows 10 later.
Another situation that you may receive message saying Diskpart cannot extend the selected partition is that the partition you want to extend has FAT32 file system. As you know, the partition on Windows PC usually has FAT32 or NTFS file system. You can only extend NTFS partition with Diskpart command on Windows 10. Therefore, Diskpart will pop up message showing that the selected partition cannot be extended if you choose an FAT32 partition to expand.
On a computer, there are two kinds of partitions, namely system partition and data partition. System partition is usually called C drive, on which the Windows 10 system is installed and system related data is stored. The rest partitions are known as data partition. Diskpart cannot extend system partition on any computer, so you may get the alert message reporting the selected volume was unable to be extended if you want to extend system partition with Diskpart command on Windows 10.
Above all, you may be clear the limitations of Diskpart command for disk partition resizing on Windows 10, namely:
1. Diskpart can only extend NTFS partition, but it cannot extend FAT32 partition.
2. Diskpart can only extend data partition, but it cannot expand system partition.
3. Diskpart can only extend a partition when there is existing adjacent unallocated space on the same hard disk.
What can you do when diskpart command failed to extend the system partition on Windows 10? There are two other methods to expand system partition as mentioned at the beginning of this article. You can resize partition with Windows 10 Disk Management or you can use free partition software for Windows 10 to redistribute disk space on the computer.
Disk Management has not so many limitations, but you have to make sure that the unallocated space is contiguous to the partition you want to extend. Otherwise, you have to use partition software to extend system partition. IM-Magic Partition Resizer Free enables you to shrink partition to create unallocated space and then add the unallocated space to system partition easily to increase its size on Windows 10.
