A storage device is an indispensable component in a computer, no matter whether you use an SSD, mechanical HDD, or RAID array. Before saving files to a brand-new hard disk, you need to initialize this disk, create partitions on it, and then format them with a file system. After running a Windows 11 computer for a period of time, you may find that the scheduled partition size is not ideal. For example: 1. System partition C is too small and becomes full. 2. There is only one partition on a disk, but you need more to save different kinds of files. 3. There are too many partitions on a disk, causing difficulty in finding files. To solve these problems and manage disk partitions better, you need a reliable disk partition manager for a Windows 11 computer. This article introduces the native free partition manager in Windows 11 and the best free partition software for Windows 11 laptops, desktops, and tablet computers.

Native Free Partition Manager in Windows 11
As with previous Windows 10 versions, there is a native free partition manager in Windows 11. Press Windows + X together on your keyboard, and then you will see Disk Management in the list. After opening this disk manager in Windows 11, right-click each partition or the leftmost area of a disk, and you will see all operations; unavailable operations are grayed out.
In Windows 11 Disk Management, you can initialize a brand-new hard disk and create new volumes with Unallocated space. You can also delete, format, and change the drive letter of an allocated partition.
This native free partition manager in Windows 11 can resize an NTFS partition without losing data (though not 100% guaranteed). More precisely, it can shrink an NTFS partition to create a new volume, and extend an NTFS partition by deleting its contiguous volume on the right. If you want to extend a partition by shrinking another one, Disk Management cannot help you.
For a hard disk, Windows 11 Disk Management can convert a disk between MBR and GPT, but you must delete all volumes on this disk in advance. It can convert a Basic disk to Dynamic, but it cannot convert a Dynamic disk back to Basic without losing data.
Compared to the native free partition manager in Windows 11, third-party disk partition software is much more powerful. There is free partition software for Windows 11 laptop, desktop, and tablet computers.
Best Free Partition Software for Windows 11 Computers
There are many free partition software programs for Windows 11/10/8/7/Vista/XP, so which is the best one? The GUIs of disk partition software programs are different, but their functions are similar. Data protection ability is the most important factor for partition software, because there is a potential risk of system/partition damage while modifying disk partitions. Better than other tools, NIUBI Partition Editor has more powerful data protection technologies and other advantages.
1. Clean and Safe
NIUBI Partition Editor Free Edition is 100% clean without any bundled advertisements or plugins. Unlike other free partition software that disables many abilities, NIUBI Free Edition is the same as the commercial edition except that it lacks the 1-Second Rollback and bootable media builder.
2. Virtual Mode
Unlike Disk Management, which applies changes immediately, NIUBI Partition Editor is designed to work in virtual mode first. You can preview, cancel, and redo pending operations. Real disk partitions will not be changed until you click "Apply" to confirm.
3. Cancel-at-Will
This is a unique technology of NIUBI. If you have applied changes with other software, you cannot cancel ongoing operations at the beginning or over 50% progress, even if you made a mistake. NIUBI Partition Editor can cancel operations at any progress quickly and safely.
4. 1-Second Rollback
This is another unique technology of NIUBI Partition Editor. If it detects any hardware issue or known software error, it is able to revert your computer to its original status automatically and in a flash.
5. Much Faster
When you shrink a partition rightward or move a partition, all files in this partition will be moved to new locations. It takes a lot of time if there are a large number of files. NIUBI is 30% to 300% faster because of its special file-moving algorithm.
6. All-in-One Toolkit
This free partition software supports Windows 11/10/8/7/Vista/XP. It can manage any types of HDD, SSD, and RAID arrays. VMware, Hyper-V, USB drives, and memory cards are also supported. Most disk and partition management requirements can be fulfilled.
