FAQs

In addition, this part lists several relevant tips about this topic. Please get an overview of them below if you're interested. 

1. Why is Extend Volume greyed out in Windows 11?

Because there is no unallocated space immediately next to the partition you want to extend. Disk Management only supports extending into adjacent unallocated space.

2. Can I extend a partition if the unallocated space is on the left side?

No, Disk Management requires unallocated space to be on the right (after) the partition. If it’s on the left, the option will be greyed out.

3. Does the file system affect Extend Volume availability?

Yes, only NTFS (and ReFS in some cases) supports extending. FAT32, exFAT, or other file systems will disable the “Extend Volume” option.

4. Why can't I extend the C drive in Windows 11?

Because a Recovery Partition or another system partition is blocking the unallocated space. This prevents Disk Management from extending C:.

5. Can I move partitions to enable the Extend Volume option?

Not in Disk Management. You need a third-party tool like EaseUS Partition Master to move partitions and make unallocated space adjacent.

6. Does MBR vs. GPT affect extending volumes?

The answer is YES. MBR disks have more limitations (a maximum of 2 TB per partition and only 4 primary partitions). These restrictions can cause the Extend Volume to be greyed out.
