DiskGenius Review 2026
DiskGenius (formerly PartitionGuru) is a Chinese-developed disk utility that has quietly become one of the most searched partition tools on Bing, with over 154,000 monthly impressions. Originally built for the Chinese market, the software now ships with a full English interface and offers a surprisingly capable free tier covering partition management, data recovery, disk cloning, and backup. This review examines whether it holds up against Western alternatives like AOMEI, EaseUS, and MiniTool.
Quick Verdict
DiskGenius Free is a capable and genuinely free partition manager with stronger data recovery than most competitors at this price point. Its interface is less polished than EaseUS or AOMEI, and the partition management features in the free version lag behind AOMEI Partition Assistant Standard. Best suited for advanced users who want recovery capabilities alongside basic partitioning — without paying.
Quick Answer
Is DiskGenius safe and free to use?
Yes, DiskGenius Free is safe and legitimate software from Eassos Ltd. The free version covers partition management, file recovery preview, backup, and basic cloning. No malware or bundleware. The Pro version ($69.90) unlocks full data recovery and advanced backup scheduling. Download only from the official diskgenius.net website.
What Is DiskGenius?
DiskGenius is developed by Eassos Ltd., a Beijing-based software company founded in 2009. The software integrates four distinct modules into a single application: partition manager, data recovery engine, disk backup tool, and virtual disk manager. This all-in-one approach differentiates it from tools like AOMEI that focus on one area.
The free version is genuinely functional, not crippled. You can create, delete, format, resize, and clone partitions without any payment. The most significant free-version limitation is in data recovery — you can scan and preview recovered files for free, but restoring more than 1 GB requires the Pro license.
Feature Breakdown
Partition Management
DiskGenius handles all standard partition operations: create, delete, format, resize, move, split, merge, hide, and assign drive letters. The visual disk map gives a real-time view of your partition layout. One standout feature is the ability to browse partition contents directly within the application before making changes — useful for verifying you are working on the correct partition.
Resize and move operations work reliably in our testing on both MBR and GPT disks. The software correctly handles both NTFS and FAT32 partitions. Advanced users will appreciate the ability to edit partition sectors directly — a capability rarely found in free tools. However, the GUI workflow for common tasks like extending C: drive requires more steps than AOMEI's drag-and-drop interface.
Data Recovery
The data recovery module is DiskGenius's strongest feature and what separates it from pure partition managers. The software can recover deleted files, restore data from formatted or corrupted partitions, and even recover files from RAW file systems. The scanning engine is fast — a 500 GB NTFS scan completes in approximately 20 minutes on an SSD.
File preview works for free: images, documents, videos, and audio files can be previewed before committing to recovery. This allows you to confirm the file is intact before purchasing the Pro license. Recoverable file types exceed 200 formats. In benchmark tests against Recuva and EaseUS Data Recovery Wizard Free, DiskGenius recovered a comparable number of files.
Backup and Clone
DiskGenius Free includes sector-by-sector disk/partition cloning and image backup. You can create a backup image of an entire disk or selected partitions and restore it later — entirely free. The image format is proprietary (.pmf files), meaning you need DiskGenius to restore them. This is a limitation compared to Paragon's more portable backup formats.
Clone operations support disk-to-disk and partition-to-partition cloning, including OS migration to a new SSD. Unlike AOMEI Free, which requires a paid license for OS migration, DiskGenius offers this feature without charge. In testing, OS migration to a smaller SSD completed successfully with automatic partition adjustment.
