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

Merging two drives in Windows 11 involves combining two separate storage spaces into one. This process is done using the Disk Management tool in Windows 11. By following a few simple steps, you can consolidate your drives, which can help optimize your storage and make file management easier.

How to Merge Two Drives in Windows 11

Merging two drives in Windows 11 will combine the storage space of both drives into a single drive, simplifying your file storage and potentially freeing up some space.

Step 1: Open Disk Management

Start by opening Disk Management.

You can do this by right-clicking the Start button and selecting “Disk Management” from the menu.

Step 2: Back Up Your Data

Ensure you back up any important data from both drives.

Merging drives will delete all data on the secondary drive, so it’s crucial to store any important files elsewhere before proceeding.

Step 3: Delete the Volume on the Second Drive

Right-click on the volume you want to merge with another, then select “Delete Volume.”

Deleting the volume will make the space unallocated, which is necessary for merging.

Step 4: Extend the Primary Volume

Right-click on the primary drive (the one you want to keep) and select “Extend Volume.”

The Extend Volume Wizard will guide you through the process of adding the unallocated space to your primary drive.

Step 5: Follow the Wizard Instructions

Complete the Extend Volume process by following the on-screen prompts.

This will merge the unallocated space from the deleted volume with your primary drive.

After completing these steps, the secondary drive will no longer appear separately in File Explorer. Instead, the primary drive will have increased in size, encompassing the space from the deleted volume.

Tips for Merging Two Drives in Windows 11

  • Always back up your important data before starting the process.
  • Make sure both drives are properly connected and recognized by Windows.
  • If one of the drives contains the Windows OS, it cannot be deleted or merged.
  • Consider using a third-party partition manager if Windows Disk Management doesn’t meet your needs.
  • Ensure your primary drive has enough space to accommodate the additional storage.
