Increase C drive space in Windows Server 2008

What will you do if C drive is full in Windows Server 2008? Nobody likes to start from scratch to reinstall Operating System and applications, but if you contact some OEM server manufacturers, you may get reply to back up, recreate disk drives and restore everything. It sounds not difficult, but if you do like that, your whole happy weekend will be wasted. The worst, server is offline during this period. Actually, you can increase C drive free space in Windows Server 2008 with disk space in other volumes.

Which tool to increase partition size

Windows native Disk Management has the ability to decrease and increase partition size, but both Shrink Volume and Extend Volume functionalities are limited. To increase C drive space with Extend Volume, there must be adjacent Unllocated space on the right side of C drive. But the Unallocated space is behind D rather than C after shrinking with Shrink Volume.

You can get adjacent Unallocated space by deleting drive D, but in that case, all Windows services and programs will be deleted or become invalid. In addition, if D is Logical partition, you still cannot increase C drive space by deleting D, because Extend Volume is grayed out.
