Partitions are spaces on storage devices used to preserve specific data sets. Each of the partitions can have their own file systems and other features that distinguish them from one another. Merging partitions in Windows 11 refers to a practice where you combine two or more of these partitions into a single unit.

If you are tired of having multiple partitions and want to manage your storage units better, we will teach you how to merge two or more partitions in Windows 11. But first, let's check out some reasons why you may decide to combine partitions in Windows 11.

Reasons Why You Should Combine Partitions in Windows 11

The reasons behind partition merging will differ depending on your preferences and personal desires. However, we will list some of the most common reasons why you should combine two partitions into one:

  • Easier management – by merging two partitions into one, you will be able to manage your storage better and avoid clutter.
  • 😃More free space – when you merge a smaller, unused partition with a larger one, you will gain more free space.
  • 🚀Preparing for larger operations – if you want to, for example, install a large virtual machine, you may need a larger partition to support your operation.
  • 💁Customization – if you decide to merge partitions, you can completely customize your experience and create a storage unit that fits your preferences and needs.

How to Merge Partitions in Windows 11

There are two free, built-in ways you can merge partitions in Windows 11. We will present step-by-step guides for both methods.

Option 1: Merge Partitions in Windows 11 Using Disk Management

Disk Management is a built-in tool that allows you to control, merge, delete, format, and manage your partitions and storage units. The tool is very advanced and can help you maximize your disk's productivity and efficiency.

When it comes to merging partitions, there are three scenarios to consider. We will present guides for each scenario below.

Merge adjacent partitions

Adjacent partitions are partitions that stand next to each other. The merging process is the easiest with adjacent partitions, as you will see in the guide below:

  1. Open Disk Management.
  2. Right-click on the partition you want to merge. Select Delete Volume and confirm the action.
    deleting volume
  3. Then, find the partition you want to merge the aforementioned partition with and right-click on it. Select Extend Volume to complete the process.
    extend volume

It will only take you a minute to merge your adjacent partitions with this method.

Merge non-adjacent partitions

Merging non-adjacent partitions may be a complicated task since you will have to delete all of the partitions standing between the two partitions. This will cause data loss, so make sure to back up your valuables before you begin this process. Here's how to merge non-adjacent partitions in Disk Management:

  1. Open Disk Management.
    opening disk management
  2. Find the desired partitions.
  3. Right-click on the partition between the partitions you want to merge. Click Delete Volume. Repeat this process for every partition standing in the way.
    deleting volumes
  4. Lastly, right-click on the partition you want to merge and select Extend Volume.

You need to be very careful when performing this action to ensure you don't lose your valuable data.

Merge unallocated spaces

Unallocated spaces don't have a letter or data stored on them. They are empty spaces ready to be repurposed. If you have an unallocated space, here's how you can merge it with an already existing partition:

  1. Open Disk Management.
  2. Find a primary partition (usually marked with a blue color) and right-click on it. Select Extend Volume.
    extending volume
  3. Disk Management will redirect you to the Extend Volume Wizard. Follow the onscreen instructions to merge the primary partition with an Unallocated Space.

Option 2: Merge Windows 11 Partitions Using Diskpart

Diskpart is a command line you can use to control your storage. For instance, you can delete partitions, format your drives, and perform numerous other actions by using command lines. Although it might seem complicated to use at first, you can merge partitions using Diskpart by following the guide below:

  1. Open the Start menu and type in diskpart.exe.
    opening diskpart
  2. Once you enter Command Prompt, type in the list volume command and press Enter.
    listing volumes
  3. Find the partition you want to merge and remember its name. Enter the select volume command, followed by the name of the partition. Press Enter.
    selecting the volume
  4. Type the delete volume command and press Enter.
    deleting the volume
  5. The last step is to type extend and press Enter to merge the volumes.

This process is similar to Disk Management but lacks the visual parts.

If you want the best disk and storage experience, you must take care of your hardware and software. We have prepared a couple of tips to help you get the most out of your disk space:

  • Remove unwanted files – as soon as you don't need a file, you should transfer it to a different location or delete it completely to free up space for new data.
  • Manage your disk health – monitoring your disk is crucial for data preservation and the best disk experience. You should check whether your disk is failing or becoming corrupted as frequently as possible.
  • Organize – organizing your files and partitions can help you improve your disk's performance and help you navigate your storage better.
  • Take care of the hardware – if your hardware becomes damaged, you won't be able to use the storage in question. Make sure your tool isn't exposed to dust, water, and humidity to keep it up and running.
  • Secure your data – using security tools, such as disk encryption, is essential in the modern world. Cybercrime is all around us, and you should ensure no one will be able to access or steal your digital valuables.
  • Always back up your data – backing up your data will give you peace of mind; you won't have to worry if you accidentally delete something from your storage or partitions.

Option 4: Keep your operating system up to date

Imagine embarking on the partition merging journey, and suddenly, your computer starts crashing, the partitions receive random names and numbers, and you cannot proceed with your actions. This isn't an imaginary scenario; all of this can happen if your operating system isn't up to date.

Before merging your partitions in Windows 11, ensure you have updated the operating system to avoid potential issues.
