Need to Extend System Partition in Windows 10
As the user of Windows 10, have you ever been warned by Low Disk Space message on your computer? Why does this happen? The main reason is that there isn’t enough free space on your system drive. When this problem occurs, you can find that the performance of your computer isn’t as good as before. On the other hand, it will make have bad mood for work, which may directly affect your working efficiency.
When facing the problems, common users will choose to uninstall applications to release space. However, with time goes by the increasing data, cache or temporary files in your computer will still cause the same problem. To really solve the problem, it is necessary to extend system partition for Windows 10.
Enlarge C drive via Disk Management
For extending C drive, the most common way can be Disk Management, which is a Windows built-in tool. Check out the steps given below to realize how to enlarge partition C in Windows 10 via Disk Management.
1. Right click This PC and go to Management > Disk Management under Storage menu.
2. Right click system partition, choose Extend Volume and do as following prompts to extend partition.
But this way works only when there is an unallocated space very behind C drive, if there is no such unallocated space, you’ll find that "Extend Volume" greyed out.
Is there something wrong with the tool? Actually, there is nothing wrong. The fact is that the function of "Extend Volume" in Windows 10 is only available when there is unallocated space behind system partition.
In such condition, if you have to increase capacity of C drive, you can delete the partition very behind C drive to get such unallocated space.
If your hard drive was initialized as master boot record (MBR) partition style, you cannot add unallocated space in extended partition to a primary partition. Similarly, you cannot extend a logical partition with unallocated space.
Furthermore, Disk Management can’t move the unallocated space freely. So Disk Management is not always suitable for you.
