How to Merge Partitions?
Why do you need to merge partitions?
To merge partitions is to combine two or more partitions together. You may need to merge partitions when:
One of your partitions is running out of space while other partitions are nearly empty.
There are a few partitions on the hard disk and you want to get a fewer number of partitions so as to make it easy to manage them.
You want to create more partitions but the number of your partition reaches the upper limit.
You can merge partitions with built-in Disk Management. However, you need to delete the other partition before merging since Disk Management cannot directly resize the partition. Fortunately, there is AOMEI Partition Assistant which can merge partitions directly without deleting other partitions in advance. Except partition merging, there are a lot of other functions provided by Partition Assistant while Disk Management does not have, such as partition/disk copy, partition recovery and partition alignment.
Before you do
This operation may change the original location of your data, so we suggest you to learn the tutorial “How to Safely Partition” before executing this operation.
You can only merge 2 partitions in one time, and the two partitions must be adjacent. However, you can merge two or more parts of unallocated space into a partition.
You can merge data partition into system boot drive, however, you cannot merge system boot drive into data partition.
"System Reserved" partition could not be merged.

Step2. In the pop-up window, tick the partition (here is H:) in the check box and select the target partition between C: and H: (we choose C: here). And then click "OK" to continue. In this case, all the data on partition H will be transferred into partition C.

Case 2: Merge unallocated space into a partition
Step1. Install and launch AOMEI Partition Assistant. In this example, there is an unallocated space before C: partition. Right click the partition (here is C:) where you want to merge unallocated space to and select "Merge Partitions" in the drop-down menu.
Merge Unallocated Space
Step2. In the pop-up window, tick the check box of which is in front of the unallocated space, and then click "OK" to continue. In this case, you cannot specify the target partition because the system partition C is selected as the target partition in default and there is no other choice.
