Facts checked 9 Oct 2026

In short

DiskGenius suits people who want a free edition that already handles resizing, splitting, GPT conversion and Windows migration4,5,9,10. Paid editions add lost-partition recovery that can save the partition table4,12. The catch: the cheapest year costs $99.90, the refund is conditional, and its pages do not list merging two partitions or FAT32-to-NTFS conversion2,3,5.

Best for: People who want a free edition that covers resizing, GPT conversion and moving Windows.
