Here is an example about resizing Windows 7 partition with Partition Assistant Home (freeware) For example, for Windows Vista/Win7/8, server 2008/2012, the system partition must be NTFS format, contiguous free space is required, etc. While sometimes the “Extend Volume” option is grayed out, what happened?Īlthough windows disk management has been improved, but to be honest, it still only provides the basic functions that do not allows you resizing the partition smoothly. Especially you can extend the volume with the adjacent unallocated space on the same disk. You are able to extend/shrink volume by yourself. It is well known that since Vista, Windows has improved its Disk Management.

How can I merge this unallocated space to C: drive?

Question: I have a simple disk configuration, only C: and D: drives, I have freed up 20 GB from the D: drive using the "shrink volume" option, but I can not merge the 20 GB unallocated space to C: drive? In disk management, the extend volume on the C: drive is grayed out.
