You can merge unallocated space Windows 11/10 or Windows 7 with the traditional Windows Disk Management or the optimizing third-party partition magic software - Qiling Partition Master, which allows the most direct way to add unallocated space to C drive or other disk volumes without affecting data.

The unallocated space is explained as a block of free space that Windows hasn't assigned a drive letter to it. Without allocation, the operating system won't recognize the space nor allow for writing files to it. To make full of the unallocated space on your hard drive, you can either create a new partition on it or merge it into an existing partition.
In Windows, the Disk Management program is where you can view the unallocated space, and this is how it looks like:
In addition, third-party alternatives also come with a disk map where unallocated space will show up. On Qiling Partition Master, this is how unallocated space displays itself:
Since the unallocated space is treated as a missing part of used space on a hard drive in Windows, why not put it in practical use right now? If you're interested in merging unallocated disk space instead of creating a new one, there are two ways for you to safely transfer the unallocated space.
Both Windows Disk Management and Qiling Partition Master enable the possibility of merging the unallocated space to the desired partition, but they differentiate each other regarding whether the two are continuous or not.
Are you seeing two more unallocated space on your computer hard drive like me? Never mind. You can manage as many unallocated partitions as you can with an appropriate partition tool. Though both tools are technically capable to handle the unallocated space, they function in totally different ways. The more unallocated space you get, the more complicated for you to solve in Disk Management. Whereas Qiling Partition Master comes handy for the purpose of making it fast, meanwhile getting it done without affecting other partitions and present data!
As you've learned in advance, Qiling partition manager software could handle one more unallocated space that is either continuous or non-continuous with the C drive, or other disk volumes you set your mind to spare the unallocated space. What's more, it is competent enough to get you out of trouble to solve low disk space even there is no unallocated space to extend the system partition.
Step 1. Locate the Target Partition.
To start extending partition, you should first locate the target partition and select "Resize/Move".
Step 2. Extend the Target Partition.
Drag the partition panel rightward or leftward to add unallocated space into your current partition and click "Proceed" to confirm.
Extra Option: Get Space from Another Drive
If there is not enough unallocated space on your disk, click on a big partition with enough free space, select "Resize/Move".
Drag the dots of the big partition to shrink it for the unallocated space and click "Proceed".
Then select the target partition that you want to extend at the allocate space to column.
Drag the dots of the target partition into the unallocated space and click "Proceed" to keep all the changes.
If your hard disk is larger than 2TB and initializes it to MBR, it will divide it into two unallocated space in Disk Management. As we know, MBR only supports disk up to 2TB. You need to convert MBR to GPT before merging unallocated space larger than 2TB.
You may try the Disk Management to convert but it is grayed out. Because the built-in tool can only convert partition format on an empty disk. Don't worry. Here is a better solution to convert partition style without wipe any data - Qiling Partition Master.
Step 1. Download and launch Qiling Partition Master on your Windows computer.
Step 2. Click the MBR disk that you want to convert and choose "Convert to GPT".
Now you can see the two unallocated space becomes one. Then you use Disk Management to merge it to another disk or apply Qiling Partition Master to merge unallocated space in Windows 11/10.
To merge unallocated space to the C drive with Windows Disk Management, you need to use the "Extend Volume" function. You must make sure that the unallocated space is continuous to the system partition. For example, it should be C: + Unallocated + D:, so that you can directly right-click on the C drive and choose "Extend Volume..." to start merging the unallocated space to the C drive. Open the Disk Management and try the steps one by one.
Step 1: Install and run Disk Management. Right-click the partition you want to add the unallocated space to and then choose Extend Volume to merge Partitions (e.g. C partition).
Step 2: Follow the Extend Volume Wizard and then click Finish.
Step 3: In the pop-up window, you will realize the size of partition has been increased.
In any case, the unallocated space is not on the neighboring right side of the C drive, you cannot add unallocated space to the C drive because the Extend Volume greyed out.
By contrast, it's more flexible to have Qiling Partition Master to deal with either an adjacent or non-adjacent unallocated space in Windows 11/10/8.1/8/7/XP/Vista. What are the overwhelming features that make it stand out when it comes to a comfortable and straightforward way to add space to the C drive without losing a single data?
1. Resize/Move partition
Where is the unallocated located? Has it to be on the right side of the C drive? What about the C drive and unallocated space is separated by the drive D, E or F? It doesn't matter even you catch up in all the situations because you are still empowered to use a simple 'drag and move' method to swallow all the unallocated space into the system drive.
2. Allocate Space
This feature is newly added in the recent software update. The most amazing part is that you don't even consider whether you currently have unallocated space or not, which saves an essential step to shrink one partition to create unallocated space in order to extend the C drive before. Windows Disk Management is not expected to own this feature in the coming days.
