How to Merge Partitions on Windows 10

Jun 08, 2020 • Filed to: Partition Solutions • Proven solutions


Computer manufacturers usually ship out their newly built PCs with partitioned internal drives. For example, they separate the drive for Windows operating system, and make another one that’s empty and ideally used for storing new data for the user. While this is recommended, you can actually opt to merge such partitions to create a single unit that stores all the files in it. This can be used to free up space that a recovery partition takes up, or to simply remove these recovery partitions. This can also help clear up unnecessary partitions you may have set up along the way.


Merging partitions happens by combining two different partitions into a single. This also means that a partition with unallocated space on the hard drive can be used to increase another partition’s capacity. There are many ways that this can benefit you, and here are some of the scenarios.


Windows 10’s very own Disk Management is capable of merging partitions. However, this does not allow files to be combined directly into the chosen partition to be used, so you have to delete the partition you least prefer before it goes ahead to transfer the allocated space to the selected partition.

1. Press Win + R to launch Run.

2. On the dialogue box that appears, key in diskmgmt.msc to launch Disk Management.

3. Locate both partitions you prefer to merge and proceed by deleting one partition first. For example, if you want to merge drives D: and C: you first have to delete the D: drive (the one without important system files). To do this, just right click on the D: drive and then select the Data Volume option.

This will delete all the data stored within the drive. If you have important files on it, perform a backup before proceeding.

4. Right click on C: system partition and choose Extend Volume on the dropdown options.

5. Follow the instructions on the Extend Volume Wizard and select default options to successfully merge the two partitions for Windows 10.

6. Once the wizard finishes, you should be able to see the merged partition with a larger disk space, which you can now use to store data.


Aside from using Disk Management in Windows 10, there are other alternative software that you can use to merge partitions. This is done by downloading and installing these following applications and following their wizard to perform the merging of partitions:

The KDE Partition Manager is one utility application that is capable of managing disk partitions, devices and file systems found on your PC. It can perform various functions for partitions such as backing up and restoring files, and as well as creating, moving, deleting, copying and resizing the partitions.

DiskGenius is an all-around utility program that has a partition manager feature, which is comprehensively designed to optimize disk use in Windows. It is capable of resizing, splitting, creating, deleting, extending, formatting, hiding, erasing and copying partitions to expand disk space.

Paragon Partition Manager is a free and Windows 10-supported application that organizes the hard drive and reallocates free space to improve the PC’s performance. It has a user-friendly interface with a wizard that simplifies the work for you. It can perform various partition tasks using its intuitive technology.

Another free software for partition merging is the Partition Logic that is capable of copying entire disks from one to the other, and also performs various hard disk partitioning and disk management tasks.

The AOMEI Partition Assistant is a free partition management software that is deemed safe for personal and commercial usage. It is packed with all the necessary features for partitioning hard drives, and as well as merging partitions. It also performs safety checks while performing such tasks, making partition management safe and efficient.


Data loss is a big concern when merging partitions, but this can be avoided if you back up your data before performing the function. Also, only perform merge partition if you are sure that it is necessary and would help improve your PC’s performance. You can go ahead and refer to an expert if you are not confident about performing such task, to ensure that your computer and data are safe even after the merge is done.
