A hard disk drive is an indispensable component in a Windows computer, no matter whether you use an SSD, a mechanical disk, or any type of RAID array. Before saving files to a brand-new disk, you should initialize it, create partitions, and format them with a file system. After running the computer for a period of time, you may need to shrink, extend, convert, or copy disk partitions, etc. A reliable disk partition tool can help you accomplish these tasks. To manage disk partitions on a Windows desktop, laptop, or tablet, there is a built-in free partition manager: Disk Management. It is able to perform some basic management operations, such as creating, deleting, and formatting partitions, and changing drive letters.
Starting from Windows 7, new "Shrink Volume" and "Extend Volume" functions were added to Disk Management. But the "Shrink Volume" function can only shrink an NTFS partition to create a new volume. The "Extend Volume" function can only extend an NTFS partition by deleting the contiguous volume on the right. To manage disk partitions in Windows, third-party software is a better choice. This article introduces the best free partition software for Windows 11, 10, 8, 7, Vista, and XP (32 & 64 bit).

The Safest Free Partition Software in Windows
There are many free partition software programs for Windows 11/10/8/7/Vista/XP computers, so why is NIUBI Partition Editor the best? Because it is the safest and fastest partition manager.
Unlike read-only programs, such as data recovery software that just reads from the hard disk drive, disk partition software will modify the parameters of the disk, partitions, and files. Sometimes, it will move all files in a partition to new locations. Therefore, there is a potential risk of system damage and data loss, especially when you resize and move partitions.
Disk partitioning software is often called a "data killer" by people who have experienced such a disaster. Thus, data protection ability is the most important factor for partition manager software. Better than other free and commercial disk partition software, NIUBI Partition Editor has advanced technologies to protect your system and data.

Virtual Mode
As you can see in block 4 in the main window, all operations are listed as pending for preview. You can click Undo to cancel an unwanted operation or click Redo to recover canceled operations. Real disk partitions will not be changed until you click the "Apply" button to confirm.
Cancel-at-Will
If you have confirmed and started the changes, other disk partition software programs, including commercial versions, do not allow canceling the ongoing operations from the beginning or over 50% progress, even if you made a mistake. Because the cancellation causes part of the parameters to be unmodifiable, it leads to system boot failure or partition damage. Thanks to the unique Cancel-at-will technology of NIUBI Partition Editor, you can cancel ongoing operations at any progress. Everything will revert to its original status in a flash.


1-Second Rollback
Better than other free and commercial partition software, NIUBI Partition Editor provides another unique 1-Second Rollback technology to ensure the system and data remain intact. If any software internal error or hardware issue, such as a power outage, occurs, it reverts the computer to its original status automatically and rapidly. If this happens, nothing will be changed.
With other partitioning software, if damage occurs, you have to waste a long time restoring everything. If you have no backup, your precious files will be lost.
With the help of Hot-Clone technology, this free partition software can clone both system and data disks without rebooting the computer.
The Fastest Free Partition Manager
When shrinking a partition rightward or moving the position of a partition, all files in this partition must be moved to new locations. A good algorithm is very helpful for reducing time, especially when there is a large number of files in this partition. Thanks to its special file-moving algorithm, NIUBI Partition Editor is 30% to 300% faster than any other free or commercial partition manager. If you have a testing computer or virtual machine, simply compare it with other tools under the same conditions.
