Setec Partition Wizard For Windows
A free, open-source disk utility that does everything the paid tools do — without the monthly subscription.
Tired of Acronis, EaseUS, and Partition Magic charging you $50/year for basic disk operations? So were we. Setec Partition Wizard is a comprehensive C++17/Qt6 disk utility covering partition management, formatting, recovery, imaging, diagnostics, security, and maintenance — all in one tool, completely free.
Features
Partition Management
- Create, delete, resize, move, merge, and split partitions with a visual disk map
- Full MBR, GPT, and Apple Partition Map support
- GParted-style operation queue — preview all changes before applying them
- Partition alignment optimization for SSDs and 4K sector drives
- Raw partition table editing for advanced users
Formatting — Every Filesystem You Can Think Of
- Modern: NTFS, FAT32/16/12, exFAT, ReFS
- Linux: ext2/3/4, Btrfs, XFS, JFS, ReiserFS, Linux swap
- Apple: HFS+, APFS (read-only detection), HFS Classic
- Legacy & Retro: HPFS (OS/2), Minix, Amiga Fast File System, BeOS BFS, QNX4, UFS (BSD), Xenix, Coherent, SysV, ADFS (Acorn), UDF, ISO9660
- Special: RomFS, CramFS, SquashFS, VFAT, UMSDOS
Yes, we support filesystems from the 1980s. Because why not.
Recovery
- Deleted partition recovery — scans for lost MBR/GPT partition entries
- File carving — recovers files by signature from MFT records, FAT directories, ext inodes, and raw byte-pattern carving
- Boot repair — rebuilds MBR boot code, fixes Windows BCD, restores GPT backup headers
- Supports recovery across MBR, GPT, and ext superblock structures
Disk Imaging
- Full disk imaging — create and restore complete disk/partition images
- ISO flashing — write ISO/IMG files to USB drives and SD cards with hybrid ISO and UEFI boot detection
- Disk cloning — sector-by-sector or smart clone (skips unallocated space)
- Checksum verification — SHA-256, MD5, and CRC32 on all imaging operations
S.M.A.R.T. & Diagnostics
- S.M.A.R.T. monitoring for both ATA and NVMe drives — read all attributes, thresholds, and health status
- Disk benchmarks — sequential and random read/write, queue depth 1 and 32
- Surface scan — find bad sectors before they eat your data
Security
- FIDO2/WebAuthn — enumerate connected security keys, manage PINs, factory reset, create/verify credentials via the Windows WebAuthn API
- Encrypted vaults — create AES-256 encrypted virtual disk containers (XTS, CBC, and GCM modes) with PBKDF2 key derivation
- Boot authentication keys — create USB-based HMAC-SHA256 tokens for application access control
- All cryptography uses Windows CNG (BCrypt) — zero external dependencies, no OpenSSL
Maintenance
- Secure erase — multiple wipe standards:
- Single-pass zero fill
- DoD 5220.22-M (3-pass and 7-pass variants)
- Gutmann 35-pass method
- Random fill and custom byte patterns
- Boot repair with MBR reconstruction and BCD rebuilding
Screenshots
Coming soon — the UI features a tabbed interface with visual disk maps, operation queues, and real-time progress tracking.
System Requirements

Design Decisions
- No exceptions — monadic
Result<T>error handling throughout - No OpenSSL — all crypto via Windows BCrypt (CNG API)
- RAII everything — disk handles auto-close on destruction
- Operation queue — changes are queued, previewed, then applied atomically
- Removable-only safety — ISO flasher refuses to write to fixed disks
- Admin required — raw disk I/O requires elevation; app checks and prompts
A Note for the Curious
"Don't forget to look UP UP at space."
Some say if you press F5 while the application is running, something unexpected happens. Something involving a riddle about nothing, a dark void, and a very particular file that only your build can produce.
Those who grew up cleaning floors on the SCS Deepship 86 might feel right at home. The janitor always did have a knack for finding hidden things.
