Necessary to increase partition size in Windows Server 2008 (R2)

With more applications or programs being installed on the Windows Server 2008 partition, the effective space will become less and less. As a result, the operation speed of applications and windows performance would be decreased. So it is necessary to increase the partition size in Windows Server 2008 (R2). Especially when the system partition is on low disk space and slow down the whole PC performance, it is recommended to extend the boot partition as soon as possible in case that causes the OS crash and data loss.

Increase Server 2008 partition size via built-in Disk Management

To change partition size in Windows Server 2008, one of the methods is using Server native Disk Management. It provides the “Extend Volume” and “Shrink Volume” features to help users increase or decrease the partition size. But both of them are only available for NTFS partition. Besides, the “Extend Volume” feature only enables you to increase one partition size when it is followed by an adjacent unallocated space. And the “Shrink Volume” can only create an unallocated space behind it, and such space cannot be moved to other location.

So, if you want to extend Server 2008 partition size via Disk Management, such as extending C drive and there being C and D partitions on the disk, you have to delete D drive first to get a contiguous unallocated space for system volume.

Then, right-click on the C drive and select “Extend Volume”. Follow the pop-out “Extend Volume Wizard” to finish the rest operations.

It is able to move unallocated space to make it adjacent to the partition you will extend. Download it and have a try.
