How to Shrink Volume on Server 2012 Freely without Data Loss


Is there a need to shrink Windows volume?

You may wonder why someone would want to shrink a Windows volume. One reason would be if you have a large hard drive and some space to spare, it may make sense to create more than one volume on this hard drive to separate system files and installed programs from personal files. Then you can shrink volume to free up some unallocated space, with which you can create new volume. Another reason is that when you want to install another operating system such as Linux, but do not have enough free space to create a new partition for it. In this scenario, you need to shrink volume to generate unallocated space.

Shrink volume with Windows internal Disk Management tool

Windows Server 2012 internal Disk Management tool contains Shrink Volume feature, so you can free up unallocated space easily. Open Disk Management console, right click the volume you want to work with and then select "Shrink" option in the drop down menu as is shown in the picture.

In the pop-up dialog box, enter the amount that you want to shrink. After that, you will see an unallocated space right next to the volume.

Tip: The size of the available shrink space can be restricted by the amount of space currently allocated to on the hard drive, that is to say, you can shrink a volume only up to half of the free space.

 You cannot shrink a volume beyond the point where an unmovable file is located. If there is some system files on the partition, you may find the available shrink space is too low, sometimes, even 0MB in size. If you want to shrink more space, you can use another tool.
