High-performance NTFS analysis and defragmentation desktop application built in Rust with a custom egui/eframe interface.
RustDefrag GUI combines low-level NTFS cluster operations with a modern real-time visualization layer:
- Live cluster map for free, used, fragmented, moving, done, and system regions
- Real-time analysis feedback with animated progress and map updates
- Defragmentation pipeline with background worker execution
- Dashboard panels for volume, analysis report, and defragmentation results
- Built-in charts for distribution and performance trends
- Native Win32 filesystem control integration (
FSCTL_GET_VOLUME_BITMAP,FSCTL_GET_RETRIEVAL_POINTERS,FSCTL_MOVE_FILE) - Worker-thread architecture to keep UI responsive
- Capped parallel analysis pool to prevent full CPU saturation
- Boot-time retry support for locked files (
MoveFileExW) - File whitelist support for highly volatile system/update artifacts
- Custom-drawn rich UI (panels, map, charts, counters)
- Windows 10/11 (x64)
- Rust stable (MSVC target recommended)
- Administrator privileges recommended for full raw-volume visibility and defrag operations

- Defragmentation touches low-level disk structures and should be run carefully.
- Use backups and avoid force-stopping the app during active relocation operations.
- See SECURITY.md for vulnerability reporting.
