Ready to merge those partitions? Follow these steps to combine partitions in Windows 11 and get the most out of your disk space.

Step 1: Open Disk Management

Start by pressing Win + X and selecting "Disk Management" from the menu.

Disk Management is a built-in utility in Windows 11 that allows you to manage your hard drives, including merging partitions.

Step 2: Backup Your Data

Ensure you back up any important data before proceeding.

While merging partitions is usually safe, there’s always a risk of data loss. A backup keeps your files safe.

Step 3: Delete the Partition You Want to Merge

Right-click on the partition you want to combine with another, and select "Delete Volume."

Deleting a volume will erase all data on that partition, so double-check if you’ve backed up everything important.

Step 4: Extend the Remaining Partition

Right-click on the partition you wish to keep, and select "Extend Volume."

The "Extend Volume" option will allow you to merge the free space from the deleted partition into the remaining one.

Step 5: Follow the Extend Volume Wizard

Complete the process by following the Extend Volume Wizard instructions.

The wizard will guide you through the steps, asking you to specify the amount of space to extend, which should be the entire free space available.

After merging, you should see a single, larger partition. Any data you had on the partitions is now combined into one, making it easier to manage and potentially speeding up your system.
