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

Worked remotely Worked remotely. I had a server that needed the C partition extended. The built in disk partitioning software wouldn’t work with the configuration. I was able to remotely shrink and move the d partition and expand the c partition. Worked great.

NIUBI Partition Editor is a very good partition utility .. I believe I got this through BitsduJour as a free offer with paid upgrades: I used it to re-partition a Windows 7 Pro PC in my living room: to split the primary disk into a smaller C: partition containing the Win-7 Pro O.S., with a logical partition containing the rest of the drive space for storage of backup images via the local network. Worked like a charm, no problem.

Niubi Saved The Day For Me I can't say enough about how good this product worked for me when Windows 10 had me looking at having to reinstall the OS. During one of the Windows Updates, an OEM partition somehow got injected into my HDD between the C and D drives. This stopped me from extending my C partition as the OEM partition was not moveable with Windows Disk Manager. NIUBI let me move the stubborn and unwanted partition so that I could easily expand C. This took only minutes but took a big load off my mind and saved the day as far as not having to spend days reinstalling an OS from scratch. What was even more impressive was that tech support got back to me late at night and again early the next morning when I contacted them with questions about the capability of the product. I couldn't ask for anything more for a game saving tool and its support. Thank you NIUBI. Barry
