CampTune makes your Boot Camp Windows partition freely resizable. You may need to adjust the size of your Windows partition when, for example, you run out of disk space or want to install an application with particularly high storage requirements. CampTune provides a simple slider to redistribute storage space between Macintosh HD and Boot Camp Windows partitions. The resize operation is safe, fast and easy.

Manage disk space on Macs with Boot Camp

• Redistribute storage space between Mac and Windows anytime
• Safe, easy and compatible with the latest macOS versions, including 10.13 High Sierra
• Support technologies such as Fusion Drive, System Integrity Protection and the new Apple File System

How it Works
To redistribute storage space between macOS and Windows with Paragon CampTune, simply move the partition size slider and click Resize. Alternatively, type in the exact size in gigabytes for either partition.

Note that any changes to system disk partitions can only be made in a special boot environment called macOS Recovery mode. This is because the system disk configuration is a critical area of macOS guarded by the System Integrity Protection technology. CampTune guides you through the creation of a special bootable drive which is then used to start your Mac and safely resize the partitions. It will take a few minutes to create the required bootable media files; you will need a 1 GB or larger removable storage device like a USB stick or an SD card.
