Why Need to Redistribute Disk Space in Windows 10?

Simply say, the reason why you need to redistribute disk space in Windows 10 is that there is not enough free space on disk partition, especially system partition. The partition on which Windows 10 OS is installed is usually called system partition. Usually, Windows users like to install operating system on C drive, so C drive is also known system partition. Probably, you only allocated little free space to C drive when installing a hard drive on your computer. Or the system partition gets full day by day since you have installed too many programs on it.

When a system runs out of disk space on Windows 10, you may receive message that you are running out of disk space on local disk C, to free disk space on this drive by deleting old or unnecessary files. Usually, you had better not delete files from system partition because it might cause system crash after deleting data that is related to OS. In this situation, you need to redistribute disk space in order to fix the system partition low disk space problem on Windows 10.

Windows 10 Resize System Partition Free with Disk Management

If you feel it complex to reinstall operating system or repartition hard disk, you can also resize system partition free on Windows 10 with Disk Management. You just need to open Disk Management on Windows 10 and right click a partition that has enough free space. Then, you can select "Shrink Volume" option to squeeze some unallocated space. Then, you can right click the system partition and click "Extend Volume" option so as to add the unallocated space to it. It sounds easy to resize system partition with Windows 10 Disk Management, but the most difficult thing is to move the unallocated space close to system partition in order to add it to extend the system partition. If the unallocated space is not contiguous to the system partition, Windows 10 "Extend Volume" will be disabled under Disk Management.

Do You Need to Resize Data Partition on Windows 10?

In addition to system partition, the rest partitions are usually used to store different kinds of data or you can install programs on those partitions. In my opinion, you do not need to resize hard drive if it is a data partition that is nearly full. You just need to delete all unnecessary files or move some data to another drive to resolve the problem. Of course, you can also open Disk Management to resize data partition if you want.
