How to Extend Non Adjacent Partitions in Windows Server/PC

When C drive is getting full, nobody likes to reinstall Operating System and all programs. Many people try to extend C drive with Windows native Disk Management but failed. "Extend Volume" option is grayed out after shrinking D drive. If you want to extend C drive with nonadjacent partition E, Disk Management is useless, because "Extend Volume" is always disabled, no matter you shrink or delete E: drive. In this article, I'll introduce how to extend non adjacent partition in Windows server and PC without losing data.

Can't extend non adjacent partition using Disk Management

In Windows 7 and all subsequent versions, there's Extend Volume function in Disk Management console, but it cannot extend non adjacent partition. It can only extend a NTFS partition when there's contiguous Unallocated space on the right and on the same disk. As you see in the screenshot, Extend Volume greyed out for C and E drive, because C drive is non adjacent to the Unallocated space and E is on the right.

To extend non adjacent partitions in Windows PC/Server, you need third party software. There are many tools in the market, but you'd better make a backup in advance and run the safest tool.

Take care of data when moving and extending disk partition

When extending non adjacent partition, all files in the middle partition will be moved to new locations. Therefore, any slight error could cause data loss and system damage. This is the reason why I told you to back up in advance and run safe partition software.
