How to Merge Disk Partitions in Windows 10

While having distinct partitions on your hard drive for distinct applications is useful, there may be occasions when you need to combine them into a single contiguous unit. Whatever your motivation, you’ve come to this page because you want to combine several computer partitions into one, ideally without losing any data. So, today, we’ll demonstrate how to use Windows 10 machines’ built-in Drive Management, AOMEI Partition Assistant, and the command-line utility DiskPart to combine (merge) numerous hard disc partitions into a single unit (command prompt or cmd).

Merge Multiple Hard Disk Partitions in Windows 10

Disk Management, a built-in partition management tool available in Windows 10, can be used to combine or merge several partitions. To combine disc partitions in Windows 10, however, you may also utilise third-party programmes and even the command prompt (cmd). Each strategy has different benefits and drawbacks, and we will outline which way is best for each objective in this section. So without further ado, let’s look at the many ways you can enlarge an existing partition in Windows 10 and combine (merge) multiple partitions into a single contiguous unit.

Things to Remember Before You Merge Partitions in Windows

Your HDD or SSD can be simply partitioned.

using the Disk Management programme that comes with Windows. It can carry out fundamental operations including deleting, formatting, and creating new volumes, all of which are necessary to manage a PC’s storage architecture. Disk Management doesn’t, however, offer any true Merge functionality. Instead, unallocated neighbouring space to the right might be added to enhance the size of a partition (volume). The requirement to wipe all data in the add-on area in order to merge it with another partition is yet another significant flaw in the Disk Management programme.

We will also use a third-party disc management programme in addition to Disk Management to merge or combine two partitions. Most of these tools enable you to construct a single huge, continuous volume without losing data by adding non-adjacent unallocated space. They generally also feature superior user interfaces and are simpler for casual consumers to utilise. EaseUS Partition Master, MiniTool Partition Wizard, Paragon Partition Manager, AOMEI Partition Assistant, and more partition management programmes are available for Windows. The Merge function is supported by nearly all of them. Finally, we’ll cover how to combine partitions on a Windows machine using the DiskPart command-line programme.

Method 1: Using Disk Management (Data Loss)

Having said that, here’s how to combine numerous Windows 10 volumes into one:

  • Go to Control Panel and search for Disk Management . From the results, click on Create and Format Hard Disk Partitions .

You will lose the data if you use this approach, so make a complete backup of Windows 10 first.

  • Locate the two partitions you want to merge and then delete the one on the right. For example, to merge / combine D: and E: drive in my PC, I ll have to first delete E: drive. For that, right-click on partition E: and select Delete Volume .
  • You ll get a warning saying all data will be lost. Click on Yes to continue.
  • Now right-click on volume D: and click on Extend Volume .
  • You will now see the Extend Volume Wizard that will let you choose how much you want to expand the disk. Click on Next to start the process.
  • Accept the default options and click on next without changing any of the values.
  • Finally, click on Finish to fully merge two partitions into one.
  • As you can see, I have successfully merged (combined) partitions D: and E: into one on my Windows 10 PC.

Method 2: Using Third-party App (Without Data Loss)

Note:Run > diskmgmt.msc is another way to launch Disk Management.

  • Firstly, download and install AOMEI Partition Assistant (Free). Now open it and right-click on the partition whose size you want to increase. From the popup menu, choose merge Partitions .
  • Now pick the partition you want to add onto the parent partition [1] and select the volume lable [2]. Finally, click on OK .
  • You have now successfully merged two partitions in Windows 10 without losing data.

Method 3: Using DiskPart (Data Loss)

Note:While the majority of the other apps on our list, including the ones stated above, provide the merging function, we’re utilising AOMEI Partition Assistant for this demonstration.

  • Type diskpart.exe (without quotes) in the Windows Search Bar and hit Enter.
  • In the command line window that comes up, type list volume and hit Enter
  • Now type select volume <label> (without quotes) and hit Enter. For example select volume e if E: is the partition you want to merge.
  • Type delete volume to make that volume ready for merger.
  • Now select the partition you want to extend. For that, type in select volume <label> to shift the focus to that volume. In this case, I ll type in select volume d and hit Enter.
  • Finally, type extend to extend this partition. You should get the message DiskPart successfully extended the volume .

In Windows 10, you can also combine two partitions using the DiskPart command-line tool. Voici how to do it:
