A high-performance storage analyzer for Windows 11 built with C#, .NET 8, and WinUI 3. Recursive directory traversal, interactive Sunburst and Treemap visualizations, full Windows Explorer shell controls, and 100% private offline processing.
Voltrex Light
Ready
Voltrex Light replaces sluggish legacy utilities with a modern 64-bit engine designed for today's terabyte SSDs and complex NTFS partition structures.
Multi-threaded asynchronous file system crawler with UI update throttling (~60 ms). The application never locks or stutters even while processing millions of nodes across NVMe drives.
Detects NTFS reparse points, symbolic links, and volume mount junctions. Prevents infinite recursion cycles and eliminates inaccurate double-counting of physical drive storage.
Seamlessly toggle between Filelight-style Radial Sunburst and Squarified Treemap charts. Features double-click drill-down, depth scaling (1-6 layers), and breadcrumb navigation.
Multi-column sortable table showing exact bytes, % of Parent, % of Root, file counts, and modification stamps. Features instant in-memory filtering with Ctrl + F search.
Direct access to Explorer context menus: Show in Explorer, Open, Open With, Copy Path, Scan from here, Recycle Bin, and Permanent Delete with safeguards.
Operates entirely offline. No cloud accounts, no data tracking, and zero diagnostic telemetry. Your directory paths, filenames, and file sizes never leave your device.
Different disk cleanup tasks benefit from different visual models. Voltrex Light integrates both with instant one-click switching.
The center disc represents the root folder, while concentric outer rings depict descending folder depths. Angular intervals maintain strict parent-child spatial containment.
Uses the Bruls, Huizing, and van Wijk layout algorithm to optimize rectangle aspect ratios close to 1:1, maximizing space efficiency and legible labels.
Voltrex Light is compiled as a self-contained 64-bit Windows binary with zero third-party telemetry dependencies.
