Server 2008 Shrink Extend Partition
How to shrink and extend volume on Windows Server 2008?
All the sizes of physical disk partitions or RAID array virtual drives are allocated while building the Windows 2008 Server, however, the scheduled size may not always meet your needs, for example:
- System partition was created too small and no free space left after a long time.
- To manage files more effectively, you need to shrink the large partition and create more smaller ones for different usage.
- A data partition is too small, but files keep going into it.
Comparing to the previous Server Operating Systems, Windows Server 2008 Disk Management console provides new feature – “Shrink Volume” and “Extend Volume”, which can be used to decrease and increase partition size. However, you cannot extend the system C drive by shrinking other data drive in this console. In this article, I’ll show you how to shrink volume and extend volume on Windows Server 2008 (R2).
Overview:
How to shrink partition on Windows Server 2008?
– Steps to shrink partition under Disk Management
Step 1: Click Server Manager next to Start on bottom left to open Disk Management console. Right click the partition and select “Shrink Volume“.
Step 2: In the pop-up window, type the value how much free space to shrink from the C drive.
Step 3: Click “Shrink” and the operation complete in a short time. Original 120GB C drive becomes 10GB and the unused space becomes Unallocated.
– Steps to shrink partition with 3rd party software
Step 1: Launch NIUBI Partition Editor and you’ll see the disk partition layout, which is similar with Disk Management. Right click the partition you want to shrink and select “Resize/Move Volume” feature.
Step 2: In the pop-up window, drag right border leftwards to shrink this partition.
Step 3: Click OK and back to the main window, where you’ll see that original C drive shrank to 30GB and the unused space becomes Unallocated. Click “Apply” button on top left to execute.
Compare with Disk Management and 3rd-party software
- When you shrink a partition, unmovable files (for example, the paging file or the shadow copy storage area) are not automatically relocated and you cannot decrease the allocated space beyond the point where the unmovable files are located. In this case, you can only shrink a little space.
- When you shrink a partition, the Unallocated space can only be created behind it.
- The Unallocated space shrank from a partition can only be used to create new partitions.
- You can shrink volume to any size, because it is able to move files.
- You may drag either left or right border of this partition to shrink, so the Unallocated space can be created before or behind this partition.
- Besides creating new partitions, the Unallocated space can be used to extend any drive in the same disk.

Step 1: Right click the drive that has plenty of free space and select “Resize/Move Volume“.
Step 2: In the pop-up window, drag the left border rightwards to generate Unallocated space.
Click OK and back to main window, where you’ll see 20GB Unallocated space created behind C: drive.
Step 3: Right click C: drive and select “Resize/Move Volume” again. In the pop-up window, drag the right border rightwards to hold the Unallocated space.
Step 4: Click OK and back to the main window, where you’ll see the 20GB Unallocated space added into C: drive. Click Apply on top left to execute, done.
Compare with disk management and 3rd-party software
- Server 2008 Disk Management can only extend a volume when there is adjacent Unallocated at the right side.
- 3rd-party software has the ability to move the Unallocated space, so it is able to extend C drive by shrinking any other data drives.
