Aomei Partition Assistant Professional Portable

: Split large partitions into smaller ones or directly allocate free space from one partition to another.

Windows 11 requires UEFI and GPT. Older Windows 10 machines often use MBR. The Professional edition enables one-click conversion of a system disk from MBR to GPT (and vice versa) without reinstalling Windows or wiping the drive. This is high-risk, high-reward—but AOMEI’s algorithm is proven stable.

: Fully optimized for modern operating systems, it provides extensive utility across Windows 11, 10, 8.1, 8, and 7. The Core Features of the Portable Suite

Combine two adjacent partitions into a larger one to consolidate space.

The ability to carry a full-featured, professional-grade partition manager in your pocket, launch it on any Windows device without installation, and perform complex tasks like OS migration, partition recovery, and dynamic disk management is a superpower.

The portable version asks for a license key every time. Solution: AOMEI portable saves license info in a License.dat file inside the USB folder. Ensure the USB is not write-protected. If missing, contact support to reactivate.
