Need to resize partition in Windows Server 2003 flexibly

On April 24, 2003, Microsoft released Windows Server 2003, also named Win2K3. Compared with Windows Server 2000, Win2K3 not only inherits predecessor's advantages but also develops extra new special features. What's more, in order to take-up all benefits of Microsoft .NET and to connect systems, equipments, information and users, it has been strengthened greatly. So Windows Server 2003 could perform much better, along with enhanced safety, practicality, reliability and extendibility. That’s why it has enjoyed great popularity among users.

However, there is nothing we can say perfect in the world. Win2K3 also has its constraints which mainly lie in hard drive management. For example, we often meet difficulty in programs updating or installing because of low disk space. And the built-in Disk Management does not allow us to move unallocated space to extend a target partition.

Then what can we do? Reinstall Windows Server 2003 system to get more space? Actually, it is a somewhat time-wasting way, because you will have many preparation works to do such as backing up all files or programs. So, you might be searching for a flexible way to resize partition in Windows Server 2003.

Move And Resize Partition

TIP: When moving partition, the size of unallocated space must be equal or larger than the partition you want to move, so we suggest you shrink down to half of the D drive at least.

Step 3. Click "OK", you'll see the unallocated space is adjacent to C drive now. Then resize C drive just like resizing D partition.

Step 4. In this window, you can drag the slider bar to the right to extend C drive with the merged unallocated space.
