In fact, most of the time we need to merge C drive with unallocated space, for this avoids mixing the data of two partitions. Considering this factor, MiniTool Partition Wizard Offers another two features called "Extend Partition" and "Move/Resize Partition".
Both of them can be used to merge C drive with unallocated space on the same disk, and the only difference is that the former can deal with nonadjacent unallocated space while the latter cannot.
It is worth mentioning that both "Extend Partition" and "Move/Resize Partition" are available in MiniTool Partition Wizard Free Edition. Thus, you can download this free partition manager to have a try on Windows 10.
- In MiniTool Partition Wizard, both unallocated space and free space are marked as "unallocated". This means you can use both of them to extend primary/logical partition with this partition magic.
- For data safety, changes related to system partition will cause Windows reboot.
Next, we will show you how convenient it is to combine C drive with unallocated space by using MiniTool Partition Wizard Free Edition.

Step 3. See! The unallocated space will be merged into C drive. Now hit "Apply" button in tool bar to make this change effective.
② Use "Move/Resize Partition" to merge C drive with adjacent unallocated space
If the unallocated space is on the neighboring side of C drive, you can also employ "Move/Resize Partition" to merge C drive Windows 10. Here are the detailed steps:
Step 1. Launch MiniTool Partition Wizard to its main interface. Select partition C and choose "Move/Resize Partition" from the action panel or "Move/Resize" from partition group in the menu bar.

Hot Article: The Most Reliable Way to Extend Windows 7 System Partition
Merge Partitions Windows 10 Disk Management
Normally, to combine multiple hard drives Windows 10, the first things that comes to mind is to turn to Windows Disk Management utility to find a solution. But does it offer a way?
Next, we will show you how Disk Management works on merging C drives Windows 10 to help you make out whether it is reliable and should be the first choice.
In fact, there is no featured named "Merge Volume" or something like that in Disk Management. The only feature that can be used to merge partitions we can see, is "Extend Volume", which is added in Disk Management since Windows Vista, together with "Shrink Volume".
However, "Extend Volume" is always greyed out due to some reasons. For example: only NTFS or RAW partitions can be extended; only unallocated space and free space can be used to extend partition; only when the unallocated space or free space is following the target partition, "Extend Volume" is available.…
Thus, to combine partitions Windows 10 by using Disk Management, you need to consider more. And, in general, there are 3 situations you need to take into account:
① When it is Unallocated Space following C Drive
As we have just explained, only unallocated space can be used to extend system partition. Thus, it is lucky for you to use this feature directly. Right click partition C, choose "Extend Volume" from the menu, and follow the instructions in Extend Volume Wizard to go through all steps.
② When it is Primary Partition following C Drive
If there is a primary partition following the C drive, "Extend Volume" is inactive. In this case, you need to make that primary partition into unallcoated space before you can use "Extend Volume"to merge C drive Windows 10.
Right click the primary partition and choose "Delete Volume" to make it unallocated space at first. Then right click the C drive and use "Extend Volume" which is now available.
③ When it is Logical Partition following C Drive
If it is a logical partition following the C drive, then "Extend Volume" is also greyed out.
In this case, you need to delete that logical partition at first to make it free space.
But this is not the whole story, because free space cannot be used to extend primary partition. Thus, you still need to delete the free space to make it unallocated space. And finally, "Extend Volume" of C drive is activated, and you can use it to merge C drive Windows 10 now.
