How to Transfer Free Space from One Partition to Another in Windows 10

You install your operating system, system programs, applications, and personal data on your hard drive partition. If there is not enough space or memory on your system drive, you cannot install new applications on this partition. Existing applications on the C drive may also not work properly. Worse, your system performance may be affected.

Similarly, if there is not enough space on the data drive, such as partition D, E, F, you cannot store new data to this partition. In addition, you cannot create new documents or files from this partition.

In case, the hard drive partition of the computer is not properly partitioned when you buy it. For example, the system drive is initially partitioned with 60GB. After a year of using the PC, it turns red and gives a warning about low disk space.

Adding free space from one drive to another is the best way to make the most of your hard drive space. The extra space in the large partition will not be wasted, and the problem of lack of memory in the smaller drive will also be solved. So why don't you do it?

How to Transfer Space from One Drive to Another in Windows 10/8/7

Technically, there are a few ways to fix this problem, since the theory is that you're increasing the space of one drive by decreasing the space of another. To change the layout of an illogical partition, you can resize the partition using Diskpart , a built-in Windows tool. However, this is a roundabout way, because whether you increase or decrease the partition size, the unallocated space will not be where you want it to be.

Disk Management is also a great tool for managing your hard drive and its partitions. Disk Management has a graphical user interface that is suitable for users with limited computer knowledge. If there is unallocated space adjacent to the partition you want to increase, simply right-click on the partition and select Extend Volume. Otherwise, you can delete the adjacent partition to make it unallocated, then repeat the above steps. Remember to back up your files before formatting or deleting.

There is also the MiniTool Partition Wizard tool (refer to the article: How to move or resize Windows hard drive partition for more details).

Although Windows comes with great tools, some users still wonder if there is a way to allocate free space from one partition to another without formatting the hard drive or any partition.

Fortunately, the answer is yes. AOMEI Partition Assistant Professional provides a feature called Allocate Free Space, which can help transfer free space from one drive to another directly, such as moving space from D drive to C drive in Windows PC. To perform this task in Windows Server, you can switch to the Server edition.

It's easy and fast! In three steps, free space is magically moved from the larger drive to the smaller drive.
