How to Merge Two Drives in Windows 11: A Step-by-Step Guide

Merging two drives in Windows 11 is a handy way to organize your files and free up space. You can do this by using the built-in Disk Management tool. In just a few clicks, you’ll have one larger drive instead of two smaller ones.

Step by Step Tutorial: How to Merge Two Drives in Windows 11

Before you start merging drives, it’s important to back up your data. The process involves deleting a partition, which can result in data loss if not done correctly. Let’s get into the steps!

Step 1: Open Disk Management

To open Disk Management, right-click the Start button and select ‘Disk Management’.

Disk Management is where you can view and manage all the drives on your computer. It shows you how much space each one has and what format it’s in.

Step 2: Delete the Partition You Want to Merge

Right-click the drive you want to merge and select ‘Delete Volume’.

Deleting a partition will erase all the data on that drive. Make sure you’ve backed up any important files before doing this.

Step 3: Extend the Remaining Drive

Right-click the drive you want to keep and select ‘Extend Volume’.

Extending a volume will add the unallocated space from the drive you deleted to the drive you want to keep. This will give you one larger drive.

After completing the steps above, you’ll have successfully merged two drives in Windows 11. You’ll now have more space to store your files and less clutter on your computer.

Tips: Merging Two Drives in Windows 11

  • Always back up your data before making changes to your drives.
  • Make sure you have enough unallocated space to extend the drive.
  • You can only merge drives that are adjacent to each other in Disk Management.
  • The drive you want to keep must be formatted as NTFS to extend it.
  • If you’re not comfortable with Disk Management, consider using third-party software to merge drives.
