Windows 2012 Runs on Low Disk Space on Hard Disk Partition

"There is only little space on C drive on Windows Server 2012. System keeps reports low disk space warning message though I have deleted some unnecessary files. So I want to reallocate some free space to the C drive. As far as I know, third-party partition software is available for partition resizing. However, I have not found a good one. Can anybody recommend a useful and reliable partition tool to reallocate disk space for C drive on Windows Server 2012?"

"Can I resize hard disk on Windows Server 2012 without repartitioning hard disk or reinstalling system? The C drive is running out of disk space, but I cannot delete any file from this partition because all files are important. Can you tell me how to increase size of C drive so that I do not need to free up disk space on it?"

Partition Software for Windows 2012 Partition Resizing

If you don't want to repartition hard disk and reinstall system, you can rely on partition tool to resize the hard disk. IM-Magic Partition Resizer Server is third-party partition software, which enables you to resize hard disk when Windows Server system reports low disk space warning message on any partition. With this partition software, you can increase size of C drive without reinstalling system. You can also increase size of data partition so that you do not need to delete or move any data from the partition to free up disk space. This partition software works on Windows Server 2012, Windows 2012 R2 and other Windows Servers to help with partition resizing.

Resize Hard Disk without Partition Software

If you want to resize hard disk without relying on partition software on Windows Server 2012, you can use Windows built-in disk management tool, which can also help you perform partition resizing.
1. Extend C drive (system partition)
If Windows 2012 says low disk space on C drive (system partition), you can open Disk Management to resize hard disk.
2. Extend data volume
If it is data partition that runs on low disk space on Windows Server 2012, you can also open Disk Management to resize disk partition. In addition, you can also run Diskpart command to extend NTFS data volume.

Why Select Partition Software?

If Windows Server 2012 built-in disk management tool enables you to resize hard disk, why do you need to use partition software? Well, here are the reasons:

1. You cannot move partition under Disk Management or Diskpart command
Under Disk Management, you can extend volume and shrink volume, but it cannot help move partition. However, adjacent unallocated space is always needed in order to extend a partition. Diskpart command can extend volume on condition that there is adjacent unallocated space. Therefore, if there is no existing adjacent unallocated space, the professional partition software is a better chance because this software allows you to shrink partition to create unallocated space and also allows you to move the unallocated space close to the partition you want to extend.

2. Diskpart cannot extend system partition or FAT32 partition
If it is system partition runs on low disk space, Diskpart command will fail to extend the volume. In addition, it the partition has FAT32 file system, Diskpart command cannot extend the partition either. However, the professional partition software has no such a limitation, which enables you to extend system partition and data partition no matter it has FAT32 or NTFS file system.
