--- title: DiskGenius canonical: https://saasranked.com/software/diskgenius/ category: Disk Partition Software points: 74 rank: 6 of 12 facts_checked: 2026-10-09 --- # DiskGenius Windows partition manager with a free edition that resizes, splits, converts MBR/GPT and migrates Windows. 74 points out of 100. #6 of 12 disk partition managers. Vendor: Eassos. Website: https://www.diskgenius.com/ - The Free edition lists resize, split, MBR/GPT conversion, one-disk Windows migration and WinPE USB creation as supported [4]. - The cheapest 12-month licence is $99.90 for 1 PC; a lifetime personal licence for 1 PC is $129.90 [2]. - Professional adds saving the partition table after a lost-partition scan; Free cannot [4][12]. - The vendor offers a 30-day conditional refund; it is generally refused once the software is activated or used [3]. - Creating and formatting partitions is listed for NTFS, FAT32, exFAT and EXT4 [5]. Verdict: DiskGenius suits people who want a free edition that already handles resizing, splitting, GPT conversion and Windows migration [4][5][9][10]. Paid editions add lost-partition recovery that can save the partition table [4][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 conversion [2][3][5].
