Windows 2012 C Drive Low Disk Space Issue

"I need to reallocate some free space to C drive on Windows Server 2012 because system always reports low disk space warning message. The Operating System is installed on C drive, so I am wondering whether I need to reinstall system and reboot my computer in order to reallocate disk space for C drive. Can anybody give me some help?"

"Can somebody recommend a partition tool with which I can resize hard disk on Windows Server 2012? I want to resize hard disk because C drive is running out of disk space on Server. I opened Disk Management and attempted to resize disk there, but the Extend Volume under Disk Management is grayed out. Therefore, I want to use a partition tool to perform partition resizing so as to fix the low disk space problem on C drive."

Disk Management to Extend C Drive

One advantage of Windows Server 2012 is that Disk Management enables its users to resize hard disk by extend volume and shrink volume without repartitioning hard disk. First of all, you need to make sure there is free space on other partition on the same hard disk. Then, you can right click the partition and choose "Shrink Volume" option so that you can squeeze some unallocated space from the selected partition. When you see the unallocated space, you need to move it behind the C drive. Finally, you can right click C drive and choose "Extend Volume" option to add the unallocated space to the partition.

Limitations of Disk Management

Disk Management works as a partition tool to help resize hard disk, but sometimes you may find that the "Extend Volume" option is grayed out. Why? Well, Disk Management provides convenience for its users to resize hard disk without repartitioning hard disk and reinstalling system, but it has its limitations:

1. Unallocated space is needed in order to extend C drive under Disk Management, so you need to shrink partition to get some unallocated space first of all. The fortunate thing is that Disk Management enables you to shrink partition to create unallocated space easily.

2. You need to move the unallocated space behind the C drive. Unfortunately, Disk Management doesn't allow you to move partition. Tip: If there is no unallocated space or the unallocated space is not behind the C drive, the "Extend Volume" option will be grayed out and you cannot extend the partition.
