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.
How to transfer space from D drive to C drive Windows 10 via professional manager
1. Install and launch AOMEI Partition Assistant on your computer. Right-click the partition you want to allocate (partition D with free space) and select Allocate Free Space .
2. In the pop-up window, you are given the option to specify the space size and destination partition. Select drive C from the given list.
3. This is a virtual result. Click Apply > Proceed to make it real.
Note :
- Since it involves the system drive, a reboot is required.
- This process applies to different partitions on the same physical hard drive. Drives on different hard drives cannot be done this way.
- This version also supports command line operations, so you can resize or move partitions, etc. from Command Prompt .
It's easy and fast! In three steps, free space is magically moved from the larger drive to the smaller drive. AOMEI Partition Assistant Professional is the advanced version, and it has a Standard version with fewer functions. With this basic tool, you can also transfer space from one drive to another to redistribute free space.
Step 1: Right-click the partition with extra space and select Resize Partition to create unallocated space on the hard drive. The location of the unallocated space does not matter.
Step 2: Click Apply.
Step 3: Right-click on the partition you want to increase the size of and select Merge Partitions. In the pop-up window, you are allowed to check both this partition and the unallocated space.
Step 4: Click Apply to perform pending operations.
