Free/Best Partition Manager Software for Windows Server 2019

by James, Updated on: August 27, 2026

Whether you use an HDD, SSD, or any type of hardware RAID array, you must create and format partitions before saving files. After running the server for a period of time, you may need to shrink, extend, reformat, or convert partitions, etc. To accomplish these tasks, you need a reliable disk partition manager to manage server storage devices. This article introduces the native free partition manager in Server 2019 and the best partition software for Windows Server 2019/2022/2025/2003/2008/2012/2016.

Native Free Partition Manager in Windows Server 2019

As with previous versions, there is a native free partition manager in Windows Server 2019: Disk Management. It can perform some basic operations. For a single partition, it can create, format, and delete partitions, set the partition as Active, and change drive letters and paths. It also has the advanced ability to shrink and extend partitions. However, it only supports NTFS partitions. In addition, it cannot extend a volume by shrinking another one. In short, it can only shrink NTFS partitions to create new volumes, and extend NTFS volumes by deleting the adjacent partition on the right.

Press the Windows + X keys together, and you will see Disk Management in the list.

For a whole disk, Windows Server 2019 Disk Management can initialize a brand-new disk. It also has the ability to convert a disk between MBR and GPT, but you must delete all volumes on the disk in advance. If you need a powerful disk partition manager for Windows Server 2019, third-party software is a better choice. There are many server partition managers on the market; their interfaces are different, but their functions are similar. When choosing disk partition software for Windows Server 2019, reliability is the most important factor. The following introduces the safest and fastest partition software for Windows Server 2019/2022/2025/2016/2012/2008/2003.

First Impression

Download this partition software in a Windows 2019 server (physical or virtual machine), and you will see the main window with 5 sections.

  1. All single partitions with detailed parameters.
  2. All physical, RAID array, and virtual disks with graphical structures.
  3. Available operations for a selected disk or partition. (You will see the same options by right-clicking.)
  4. Pending Operations: all operations you perform will not be executed immediately; instead, they will be listed as pending for preview.
  5. Cancel, redo, or apply the pending operations.

Unlike other disk partition tools that list all options, NIUBI Partition Editor only lists the available operations to keep the interface clean; unavailable options are hidden automatically. Right-click a partition or the leftmost area of a disk, and you will see the available options.

The Safest Partitioning Software for Windows Server 2019

Data safety is most important to a server, but there is a potential risk of system damage and data loss while resizing partitions or making other modifications. Besides backing up, you had better run safe partition software. It takes a long time to restore everything and verify data if the server is damaged.

Better than other tools, NIUBI Partition Editor has advanced technologies to protect your system and data:

Another major benefit of NIUBI is that it can clone a disk partition without server interruption. Therefore, you can clone the system disk regularly as a backup. Whenever the system disk goes down, you just need to swap to the cloned disk. It can be done within a few minutes, making it much faster and better than restoring from an image backup.

The Fastest Partition Manager for Windows Server 2019

There are often a large number of files in a server partition. The more files there are in a partition, the longer it takes to shrink, move, and copy the partition. A good algorithm is very helpful for saving time. Thanks to its unique file-moving algorithm, NIUBI Partition Editor is 30% to 300% faster than other tools.

Because of its powerful data protection and fast resizing abilities, ease of use with a neat interface, as well as plenty of disk/partition management features, NIUBI Partition Editor is recommended as the best partition manager software for Windows Server 2019/2022/2025 and Server 2016/2012/2011/2008/2003.
