In some cases, computer users need to merge two partitions into one (e.g. C: + D: = a larger C:), add a block of unallocated space into the Windows system drive, combine multiple volumes together. Along with the demands, people start to ask questions, like "how do I make it for free", "I want to merge partitions badly, but how", "Why is there no suggestion for joining D drive and G drive, they are separated by E and F". Are you one of them who have the same questions? Read this in-depth tutorial carefully and you will find appropriate answers to all purposes of stringing together many disk partitions on one hard drive.

EaseUS Partition Master Free

It's a free partition manager that always ranks on the top recommendation for a comprehensive Windows disk & partition management solution. What makes EaseUS Partition Master popular among worldwide users? Mainly, it's about its capability of resizing, deleting, formatting, partitioning or creating a new partition on all types of storage devices. And here you're going to learn the outstanding feature called "Merge partitions".

Plan A - Merge two adjacent partitions

To merge two adjacent partitions, refer to the steps below to combine two partitions:

 

Step 1: Install and launch EaseUS Partition Master on your PC

Right-click on the partition which you want to add space to and keep on the hard drive, and select "Merge".

Run EaseUS partition manager software

Step 2: Select partitions to merge

1. Select one partition next to the former selected partition.
2. And click "OK" to continue.

Select partitions to merge

Step 3: Merge partitions

1. Click the "Execute Operation" button at the top and then click "Apply".
2. The program will merge space and add files from the second partition to the first partition.

Plan B - Merge non-adjacent partitions

If you are planning to merge two non-adjacent partitions, follow the steps for help:

 

Step 1: Launch EaseUS Partition Master

1. On the main window, right-click on the partition that you want to merge space to another and select "Delete".

2. Click "OK" to confirm. The deleted partition will display as unallocated.

Step 2: Move the unallocated space next to the target partition

1. Right-click on a partition next to the unallocated space and select "Resize/Move".
2. Drag the selected partition forward or backward, moving the unallocated space toward the target partition, and click "OK".
Repeat 1 and 2 until the unallocated space is moved next to the target partition.

Move unallocated space to the target partition

Click the "Execute Operation" button and "Apply" to keep all changes.

Step 3: Merge partitions

1. Right-click on the target partition that you need to add space to and keep, select "Resize/Move".

Add unallocated space to target partition

2. Drag the target partition handle into the unallocated space and click "OK".

Merge non-adjacent partitions

3. Click the "Execute Operation" button and click "Apply" to keep all changes.

Keep all changes

If two partitions are separated by unallocated space as listed here below, right-click on one partition (you want to keep) and select "Merge" > Select another partition and click "OK" > Keep all changes by clicking the "Execute Operation" button and "Apply".

Except applying EaseUS Partition Master free to combine partitions in Windows 10/8.1/8/7/XP/Vista for free, you can also use this feature to extend partitions such as C: drive when it's running out of space.

Windows 10 Disk Management

It's the inbuilt disk & partition management program in Windows 10/8.1/8/7. The Windows Disk Management works totally different from the EaseUS software, and the following is a simple guide for Windows 10 computers.

Step 1. Right-click on the "This PC" icon on the desktop, choose "Manage", and then select "Disk Management".

Step 2. Right-click on one target partition and select "Delete Volume" from the feature list. (Deleting a partition causes data loss. Back up important data, please.) Yes, you have to delete one partition to continue with the further steps.

Step 3. After the deletion, right-click the other target partition and choose "Extend Volume".

Step 4. Follow the Extend Volume wizard to achieve the gold of making two partitions as a one.

If you see that the "Extend Volume" option is greyed out, it's because the unallocated space produced by deleting a previous partition is not close to the selected partition.

Comparison and Conclusion

So far, we introduced you to two tools that aim to merge several partitions into a single larger one. After carefully reading, you should notice that there are some noticeable differences while applying the third-party software and the Windows inbuilt program. Pick up one partition management solution that works the best according to your own understanding.
