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.

easy to use the tool -

It worked as advertised.. It worked as advertised... Server 2016 Essentials, shrink and move the data partition to make space and then expand the system (C:) partition into that space. Worked pretty quickly too.

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.
