Can I Extend a Partition in Windows 10

Does anyone have any solutions? Although enlarging the volume on the OS-installed drive is not possible, I would like to do so. It operates flawlessly on other drives. How do I extend the volume in Windows 10?

Generally, there are three methods to extend the volume in Windows: reliable third-party tool, Disk Management, and Diskpart. If the Extend Volume option is grayed out in Disk Management, it's likely because there's no adjacent unallocated space. In this case, EaseUS Partition Master Free would be the easiest solution.

  • EaseUS Partition Master is the most flexible, allowing you to extend partitions even without adjacent unallocated space
  • Disk Management requires the unallocated space to be directly after the partition you're extending
  • DiskPart can be useful for advanced users but requires caution, as incorrect commands can lead to data loss

Below are the comprehensive tutorials:

Step 1. Download and launch EaseUS Partition Master.

Step 2. Right-click on the partition you want to extend and select "Resize/Move."

Step 3. Drag the partition's edge into the unallocated space to add more space.

Step 4. Click "OK" > "Execute Task" > "Apply" to finalize the changes.

If you don't want to use this free tool, you can try Disk Management and Diskpart. Check this guideline:
