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.

Outstanding help! It was phantastic how well and with what patience and competence I, as a computer semi literate, was helped and educated with the allocation problems I encountered with a new computer that has 2 hard disks! I now understand how this all works and many thanks for proposing solutions to my problems despite them being outside the scope of Niubi technology. Wished Microsoft would take a page out of your book! Many thanks again! Rainer

Excellent customer service Excellent customer service! We were running low on a drive on a Windows 2012 server and found this software. Ran into some road blocks with purchasing but the customer service rep was more then helpful. The software worked wonderful in expanding the disk space, no issues at all.

Just buy it! I have been a computer technician for over 20 years. After having another company's software botch my partitions in a way that I couldn't correct no matter what I did, NIUBI Partition Editor let me fix the issue quickly and easily. I would highly recommend this product to everyone!

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.
