I merged my empty D partition on the left into the main C partition on the right for free; a good product. Other tools refused to complete this operation for free because of the reverse order.

Great tool to extend server partition
We have 2 servers with Windows 2022 and 2019, both servers are running low disk space on C: Found this tool by Google, after comparing with other 3 tools, selected NIUBI, because it has more protection ability. One server was extended in several minutes and the other was extended in less than 20 minutes, well done!
Amazing free software and upgraded to pro
Found this tool on youtube following the video to convert my dynamic disk to basic. It finished in 2 minutes, amazing! Then tried other options to resize partition, scan bad sectors and cloned my old disk to a new ssd. All works well, I can't believe this is a free software. Upgraded to the pro version at last, good job!

I was finding simple for user but powerful tool, and I've found it!
Extended C partition successfully for all servers
We have many local/VM server running out of space on C: partition. Selected NIUBI enterprise edition from the disk partition software. It's easy to shrink D/E to get free space and add to C by following the online video. All work like a charm except one server that reported an error code. James from the support tell me to repair filesystem error after reviewing. After running chkdsk command and resized partitions successfully the second time. Product and support are both excellent.
Work well to extend partition and clone disk
I have Win11 laptop with C drive full, tried to clean up, remove duplicated files but did little help. Came across NIUBI Partition Editor free edition several days go and followed a youtube video. In about 6 minutes, it successfully shrunk my D and transferred free space to the C: drive. Upgraded to the pro edition to clone disk to nvme for another desktop. Nice tool
Resized EFI partition with no trouble.
I was trying to resize my EFI partition to install multiple operating systems. Tried a number of tools but only this got the job done. Recommended!
Super easy to use !
Used their tool to change some storage issues on my computer I could not manage for months. Super easy to use and powerfull. I am so glad some people devellop such solutions for random users like me. Big Up !!
easy to use the tool
Fixed
Context: I converted my old win 10 MBR disk (previously upgraded from Win 7) to GPT and upgraded to Win11, using standard Windows tools.
After this I had about a gig of a dead/duplicate "recovery" partition at the end of the disk.
This app allowed me to delete that space, move the correct Recovery and UEFI paritions to the end of the disk, maintaining their exact size, and extend the C: to use the cleared up space.
Did all that at once on one reboot, worked first try, and my PC still boots.
A++, may pay for the full version in the future.
Good Product
Good Product
Having already discussed the software’s features above, the 2 things that one looks forward to a good user experience is the device’s functional speed and overall reliability. Truth be told, the experience was more than satisfactory. Thanks to the unique file-moving algorithm, the software can resize partitions 30% – 300% faster than any other tools, which has been strictly tested by the company.
great for moving / resizing
i was having a problem with moving my partition but niubi helped me in solving it under 5 min do recommend
Everything fine
I was looking for free program which could help with moving and resizing partitions. This program did his job perfectly. Thank you
Easy to use program
Easy to use program. Add the ability to change the drive letter.
I apologize, I didn’t notice that the drive letter related to the system volume.
Windows 10 Media Creation tool…
Windows 10 Media Creation tool automatically Assigns 50MB instead of 500MB on some older BIOS computers. this causes an shadow copy error when trying to backup using windows 7 system image on windows 10 and throw a fit.
This tool solved my issue. I noticed my PC was slow after using it however I did also download EaseUS which I confirmed to be a virus so this is probably safe. I would like to know from people who have looked at the code and tell if if there is any malisious intent in the background. If not it's a 5 star product I was able to extend my 50MB System reserved to 500MB

A genuinely "FREE" for home use app
SUMMARY:
Niubi is genuinely "free" for home use, well, if you download the free edition, as of 30-July-2023, supporting Windows 11, too.
Search for these keywords (I took it from one of the earlier Niubi replies):
hdd-tool (dot com) free download
It has all the capabilities with partitions and disk management, but I was specifically interested in disk cloning. I just cloned my entire disk in few hours successfully. And no, you will not need to reveal any credit cards, or sign up for anything anywhere, or asked for codes and such.
Simply download free version, setup, and run the clone wizard to clone the disk, that's all. Kudos to Niubi developers and managers, hats off!!!
MY STORY:
I purchased a brand new m.2 type 2TB SSD yesterday. I installed it to my laptop in half hour, very easy. There're lots of videos and documents online available to show how.
Beware: do NOT buy the fastest SSD even though they're very tempting, because they come with "heat" problem. My laptop has limited ventilation and narrow space for the m.2 type SSD, so I purchased one of the coolest operating one.
Next, I needed an application which can clone my entire old 1TB conventional SATA harddisk to the new 2TB SSD. My system was in good shape, therefore I did not want to spend countless hours to re-build the operating system and setup all the other applications from scratch.
After couple hours of search and installing/testing a bunch of other recommended so called "free" applications (why you call free when you ask for codes or credit cards or sign up here and there... at the end of the day, it's not really free), finally I bumped in to Niubi.
Before downloading and testing it, I checked this truspilot website to read the comments. Majority seemed happy and gave good ratings with well deserved positive feedbacks.
As dictated on one of the earlier comment/reply, I downloaded the free edition of Niubi, and set it up.
Again, lots of videos and documents available online to show how to use it.
I cloned my 1tb harddisk to 2tb ssd easily using the clone wizard.
After the task completed, there was one partition with 1TB left unused on my new SSD due to the size difference between old and new drives. I read here on trustpilot that someone gave 1star rating for this issue alone, though it was really unnecessary since you can fix this in a minute using Niubi and Windows disk management tool. Again, there're videos to show how.
To wrap up, in few hours my system successfully switched from old and slow harddisk to the new and blaaaazing fast SSD.
I'm mesmerised from the outcome so much so that I keep turning on and off my laptop for no reason, just to watch how fast it goes on and off, beautiful!
You guys at Niubi, I can't express my gratitude to you all enough, thank you so much!
I'll recommend your product to our IT guys in the office, and everyone I know.

It Works !
I needed to expand the size of my system reserve partition, which can only be done with a third-party application.
I found the NIUBI Partition Editor and purchased it.
It's not the most intuitive I've ever seen, so I contacted the Support team. With the help of John and a video I watched, I was able to achieve my goal.
I am now a very happy camper!
Well done
Well done, it helped us extend system drive in half an hour, otherwise, it'll be a long long work...

The application was advertised as a server partition management tool (Win 2019 etc.) However, when I purchased the "pro" version I was informed (after purchase) that this version does not work with a server. I'm not happy about that deceptive move.
