AOMEI Partition Assistant
AOMEI Partition Assistant suits people who want a free edition that resizes, moves and merges partitions, or a paid one with a 90-day refund window. Professional is $49.95 a year or $69.95 once. The catch: no page names a rollback for interrupted operations, and the help page for allocating free space does not say whether partitions must be adjacent.
4DDiG Partition Manager
4DDiG Partition Manager covers most partition jobs: resize, merge, split, FAT32 to NTFS, MBR to GPT, OS migration, cloning and partition recovery. A year for one PC is $40.95 and a lifetime licence is $59.95, with a 30-day refund window. The catch: the vendor names no protection for interrupted operations, and merging works only on adjacent partitions.
