Windows Build In Tool to Resize Server 2012

delete_volume

Windows Server 2012 has two build in disk managing tool: Server Disk Management and diskpart command line. The difference between them is bootable CD is required when extends C partition in diskpart; they both require continues unallocated space to the volume you want to extend and NFTS file system to that volume. Some Server users tried these two methods to solve low disk space alert after long time use of Server 2012, they succeed, but won't try it again, only because they took too much time on deleting, extending, recovering.

For example, in Server Disk management, you have to delete partition on D Drive to make "Extend Volume" in C Drive right-click menu is active, before deleting, backup D partition is needed especially when important stuff are all stored in it. After extending system partition, you had to create partition and assign drive letter "D" again, and recover everything, but the new D partition is not the previous one, it's smaller in size, if recovery files size is larger than new D partition size, you had to Delete another partition and move some free space to new D partition again. You're complex easy stuff!
