"How do I combine partitions into one partition, without losing my data? On occasion I have tried to copy files to a MSFT standard folder but get an error there is not space. So I would like to combine the folders into one partition, there by using the full available capacity of the disk.“

▶ Option 1. Merge (combine) partitions in Windows 11 by alternative software
AOMEI Partition Assistant is one of the most popular disk management tools on the market. It aims to help users solve various complicated disk problems with the simplest steps. It supports merging two adjacent partitions or non-adjacent unallocated space without deleting partitions.

Step 1. Install and run it. Right-click the partition you need to merge, select "Advanced" and choose "Merge Partitions".
Step 2. Then, choose the partition that you need to be merged and click OK.
Step 3. After that, click "Apply" and "Proceed" to generate the final operations.
- ★Tips:
- Merge Partitions can only merge two partitions at a time. However, two or more unallocated spaces can be merged at the same time, and the unallocated spaces do not need to be adjacent.
- You can merge data partition into system partition, but you cannot merge system partition into data partition.
- If you want to complete these operations in Windows Server, please upgrade to AOMEI Partition Assistant Server.
100% Secure▶ Option 2. Merge partitions in Windows 11 with Disk Management
Windows Disk Management can help you merge partitions through Extend Volume option, but Extend Volume will be grayed out when there is no unallocated space or the unallocated space isn’t adjacent to the target drive. If to extend the C drive, you should delete the D drive to get an unallocated space.
Step 1. Open Disk Management in Windows 11 first.
Press "Windows + R", type in "diskmgmt.msc" and hit "Enter" to open Disk Management
Step 2. Next, you should delete one partition to generate unallocated space.
If you need to combine C drive, you should right-click D and select “Delete Volume”.
Step 3. Then, extend the target partition with the unallocated space.
Right-click the C drive and select the "Extend Volume".
Step 4. Follow the Extend Volume Wizard to complete extend C drive.
Here, click "Next" and accept the default options to merge two partitions in Windows 11.
Warning:
① The D drive will be deleted forever. If there are important data, please back up in advance.
② The unallocated space must be adjacent to and on the right side of the C drive. Otherwise, Disk Management does not allow you to extend the C drive with the deleted D drive.
Did you see it? Disk Management can merge partitions only when adjacent partitions are deleted. If you want to merge partitions without losing partition, then I highly recommend you to use an alternative software.
100% Secure▶Option 3. Merge Partitions Windows 11 Using CMD
If you are familiar with computer operations, you can use diskpart to merge partitions. Depending on the command parameters, you can perform partition deletions, format drives, etc.
Step 1. Open the start menu and type diskpart.exe to enter a command prompt window.
Step 2. Type the following commands to merge the partitions and press Enter after each command.
- list volume
- select volume
- delete volume
- extend
The process is similar to disk management but lacks the visualization component. And the method is technically demanding. For a safe and efficient partition merging experience, it is recommended that you choose AOMEI Partition Assistant to perform the automated process.
100% SecureConclusion
This is the full guide on how to merge or combine partitions in Windows 11. If there is an adjacent unallocated space behind the target partition, Disk Management is enough. But if there is no unallocated space behind the target partition, AOMEI Partition Assistant must be the best choice. In addition, you can also create a portable partition manager that can solve disk partition problems anytime.
