Best Free Partition Manager Software

Updated on: November 16, 2019

This article introduces the best free partition software for Windows 10, 8, 7, Vista, XP 32/64 bit. Manage hard drive with reliable partition manager tool.

Why a reliable partition tool is needed?

To manage hard disk drives, there are many choices, you may use either Windows built-in Disk Management or 3rd-party disk partition manager software. In Windows XP Disk Management, you can only do some basic management operations including create volume, delete volume, format volume and change drive letter.

From Windows Vista, Microsoft added advanced functions in Disk Management to change size of allocated partitions. Shrink Volume is used to decrease size of a drive and Extend Volume is used to increase partition size with contiguous Unallocated space, both can be done without losing data or rebooting computer. However, due to some inherent limitations, Disk Management cannot shrink or extend partition in most cases.

To resize volume, third party tools are much more powerful. In addition, they can help you do many other operations such as move, copy, convert, defrag, hide, wipe partition, etc. This article introduces the best free partition software for Windows 10, 8, 7, Vista, XP (32 & 64 bit), which is even better than many commercial partitioning software.

The safest free partitioning software

Unlike the read-only programs such as data recovery software that just read from the hard disk drive. Partition management software will modify disk partitions, so there is system damage and data loss risk, especially when you resize and move partitions. Disk partitioning software is called as "data killer" by the people that experienced such disaster.

Thus, the data protection ability is most important to a partition manager software. It is useless if it may cause data loss, no matter how many functionalities it provides or how beautiful it is. To help protect your system and data, NIUBI Partition Editor provides 3 way.

Virtual mode

1. Virtual mode

As you see the block 4 in the main window, all operations are listed as pending for preview. You can click Undo to cancel the unwanted operation or click Redo to recover the cancelled operations. The real disk partitions won't be changed until you click Apply button to confirm.

2. Cancel-at-well technology

If you confirmed and started the changes, other disk partition software including commercial version don't allow cancelling the ongoing operations from the beginning or over 50% progress even if you did something wrong. Because the cancellation causes part of parameters can't be modified, which leads to system boot failure or partition damage. Thanks to the unique Cancel-at-well technology, you can cancel the ongoing operations at any progress with NIUBI Partition Editor. Everything will back to original status in a flash.



3. 1-Second Rollback

Better than other free and commercial partition software, NIUBI Partition Editor provides another unique 1 Second Rollback technology to ensure system and data intact. If any software internal error or hardware issue such as power outage occur, it rollback the computer to original status automatically and rapidly. If it happens, nothing will be changed.

With other partitioning software, if damage occur, you have to waste a long time to restore. If you have no backup, your precious files will be lost.

The fastest free partition manager

Sometimes when you shrinking a partition or moving the position of a partition, all files in this partition must be moved to new locations. A good algorithm is very helpful to reduce time, especially when there are large amount of files in this partition. Thanks to the special file-moving algorithm, NIUBI Partition Editor is 30% to 300% faster than other free and commercial partition manager. If you have testing computer or virtual machine, simply compare it with other tools in the same condition.

File moving
