In some situations you need to shrink a volume, for example: C drive occupied all disk space after installing Windows. By shrinking C drive you can get Unallocated space to create new volumes. On the contrary, another typical issue on Windows Server 2012 is that c drive runs out of space, in this case, you can shrink partition D or any other data volumes to increase C drive space. In this article, I'll show you how to shrink partition in Windows 2012 Server without reinstalling or losing data.

Cannot shrink volume beyond limit
It is easy to shrink a NTFS partition in Server 2012 Disk Management, but you may encounter issue in some situations. Have you noticed the message in the Shrink window - "You cannot shrink a volume beyond the point where any unmovable files are located."?
If there are Paging file, Hibernation or other kinds of "unmovable" files are located, Disk Management can only shrink little space.
If the partition that you want to shrink is FAT32 (or other type), Shrink Volume is disabled.
Even if you can shrink partition without issue, you still cannot extend other partition with the Unallocated space. Learn why Extend Volume greyed out in Server 2012 Disk Management.
