Many people have been in this situation: The space of system partition is running out, while the adjacent partition has so much space left. Sometimes due to different reasons, we need to merge partitions to create a larger partition. This seemingly should not be hard to do. But in fact, merging partitions is not as easy as additive operation. In Windows built-in Disk Management, we need to delete an adjacent partition first for partitions merging (after deleting, it will become unallocated space). This is very inconvenient for the user who doesn't have an external storage disk drive. Can we just directly merge two partitions without deleting one of them? AOMEI Tech’s merge partition disk utility - Partition Assistant could be the best answer.

There is 'Merge Partitions' function in AOMEI Partition Assistant. it can very easy to merge partitions in Windows 7, 8, 10,and Windows Sever. Usually, there are two common conditions that you merge partitions:

  • Two or more than two partition have a little unused space, and you want to merge multiple partitions into a bigger one.

  • You can merge unallocated space to one partition to extend its space.

Whatever demands you have, you can use AOMEI Partition Assistant to merge partitions.

Step 1. Right click on the target partition. In the pop-up window, select the adjacent partition or unallocated space in the hard disk. Then enter the drive letter you like for the new extended partition. All the data and files will be merged into the new partition. Click OK to next step.


Step 2. You may preview the allocation of partitions in the main interface, if it’s okay, click Apply on the top left corner. Then click Proceed.


Step 3. Once the partitions merging is complete, click OK.
