Why NIUBI Partition Editor

Virtual Mode

It is common to make mistakes or change your mind after performing an operation. To avoid errors, NIUBI Partition Editor is designed to work in virtual mode. All your operations will be listed in the bottom left as pending for preview. If you spot any incorrect operations, simply click 'Undo' to cancel. The real disk partition won't be modified until you click 'Apply' to confirm.

Cancel-at-Will

When adjusting partitions, other software does not allow you to cancel the operation, even if you have made a mistake. This is because canceling may cause disk partition parameter errors or file movement errors, which could lead to partition damage or data loss.

Thanks to the powerful Cancel-at-Will technology of NIUBI Partition Editor, you can cancel the ongoing operations at any progress without destroying partitions.

1-Second Rollback

Data safety is crucial for a server, but there is a potential risk of system damage and data loss when modifying disk partitions.

To eliminate these risks, NIUBI Partition Editor introduces the innovative 1-Second Rollback technology for fast recovery. If a power failure or other errors occur while modifying disk partitions, the program automatically restores the disks and partitions to its previous state in a flash.

Hot Resize

Keeping a server online is very important. With the help of Hot-Resize technology, NIUBI Partition Editor reduces the probability of a server reboot. (Close other running programs/files before opening NIUBI. The pending operations marked with can be completed without rebooting the server.)

Bootable

Hot Clone

It can clone disk partitions in Windows without server interruption. You can clone the system disk before performing any operations or on a regular basis. If the system disk fails, you can boot from the cloned disk immediately without wasting time on restoration.

Bootable Media

Build a bootable CD/DVD/USB to resize and manage disk partitions without an Operating System. If you cannot install programs on the server, another option is downloading the portable version.

File moving

Much Faster

Sometimes, when resizing disk partitions - for example, shrinking the D drive to extend the C drive - the starting position of the D drive changes, meaning all files on this drive must be moved to new locations. This process takes a significant amount of time, especially when there is a large number of files on the drive. A good algorithm is crucial for saving time. Thanks to its advanced file-moving algorithm, NIUBI Partition Editor is 30% to 300% faster than other tools.
