We may found that the computer performs badly after using a period of time. There are some reasons, the first come into our mind is low free space in system partition. For Windows Server 2012, snap-in resizing partition features in built-in Disk Management comparing to Server 2008, 2003. It is very useful when system partition is suffering “low disk space warming” by allocating more unallocated space and improving performance of machine. However, there is still existing limitation.

When we want to extend system partition, “Extend Volume” only can be used with contiguous free space at the right side of the system partition. If there is no free space, we can shrink one existing partition to get, but “Shrink Volume” can only free up space behind the partition we shrink, while move partition is not allowed by Disk Management. To extend system partition Windows 2012, delete one existing partition behind system partition to get free space is the only way we can do in Disk Management. It is at the risk of losing data.

Under such circumstance, find a third-party partition toolkit is very important to find an easier and safer way to extend partition.
