I am a Windows Server 2003 user, and my computer has a total size of 100GB, including drive C 20GB, drive D 80GB. It has been working pretty well, but recently a serious problem happens to my computer, that is, the drive C has no free space. As a result, my computer runs more and more slowly and also some necessary programs can not be installed, either. Therefore, I decide to allocate some free space from drive D to extend system partition. Then, I launch the Disk Management, but unfortunately, it just has the function of delete and format volume, which may lead to a great data loss. Therefore, the aim of “Windows Server 2003 partition resize” becomes a headache to me.

Then I search on the Internet, and I find the AOMEI Partition Assistant, which has different editions for different Windows versions. Luckily at last, the problem of extend drive C has been resolved easily and safely. There are several ways in accomplishing the task “Extend system partition”, and next, I will introduce the detailed process to you.
