Windows native free partition manager-Disk Management

Sometimes, Windows users might need to extend partition, shrink partition, delete partition, format partition, convert MBR disk to GPT, convert dynamic disk to basic disk and more. Then, as one of the free Windows native partition managers, Disk Management will be their prior choice. To access it, right-click on “This PC”->“Manage”-> “Disk Management” under “Storage” in the left panel. Right-click a partition or disk, and all functions you can use will be displayed in the drop-down menu.

Extend Or Shrink Greyed Out

Limitations of Windows 10/8/7 Disk Management

Generally speaking, this free partition manager can help complete most disk partition management tasks. But under some special situations, this tool will let you down due to its noticeable limitations. For example:

The “Extend Volume” or the “Shrink Volume” option is greyed out when you try to extend or shrink a FAT partition. That’s because Disk Management can only extend or shrink NTFS partitions.
The “Extend Volume” is greyed out when there is not an adjacent unallocated space behind the to-be-extended partition.
The “Delete Partition” will also be unclickable when you attempt to delete volume on USB flash drive (removable device) or the recovery partition, OEM partition and more.
Disk Management only allows you to do conversion between GPT disk and MBR disk after deleting all existing volumes. And you cannot delete system partition and convert boot disk through it.
Disk Management only permits you to convert basic disk to dynamic without deleting volumes. But converting dynamic disk back to basic disk requires you to remove existing volumes first of all.

When you cannot perform the above disk partition management due to the limitations, you will need third-party free partition software.
