Camptune X

With Paragon Camptune X, for the first time, you can redistribute disk space on a Mac in minutes!
In the past, to reallocate free space on your Mac, you'd need to back up the Boot Camp partition, delete the partition, recreate an NTFS partition with a new size and, finally, restore the Windows partition backup to the new NTFS partition, a process that could take anywhere between two to five hours.

Fortunately, Paragon Software has developed Camptune X, which achieves the same result in a matter of minutes!
