DiskRaptor

Ultra-fast disk space analyzer -- A modern, cross-platform successor to WinDirStat / DaisyDisk, built with Rust + Tauri 2.

Visit the official website: https://www.diskraptor.com — documentation, screenshots and download links.

DiskRaptor scans directories using a parallel jwalk engine (macOS), walkdir (Windows/Linux) and renders results in a virtual tree view capable of handling 20+ million files without UI lag.

└──────────────────────────────┘

The UI is pure JavaScript rendered in the system webview (no bundled Chromium — Tauri uses the OS webview: WKWebView on macOS, WebView2 on Windows, WebKitGTK on Linux). Communication with the native layer uses Tauri's IPC (window.__TAURI__.invoke). The scanner is a Rust crate (diskraptor_scanner).

Features

Scanning

• Parallel jwalk engine (macOS) -- Multi-threaded directory traversal, 2-6x faster than single-threaded
• walkdir engine (Windows/Linux) -- Reliable cross-platform scanning
• Permission resilience -- Gracefully handles access-denied folders, logs errors, continues scanning
• 20M node limit -- Scans entire drives with millions of files
• Multi-path scan -- Scan multiple paths sequentially (path1; path2; path3)

Visualization

• Virtual TreeView -- Renders only visible DOM nodes, handles 10M+ files
• Pie Chart + Squarified Treemap + Bar Chart + Galaxy 3D View -- Top 50 largest files, hover tooltip, click to jump to tree
• File type icons -- Emoji icons per file type (images, video, audio, archives, code, etc.)
• Percentage bars -- Colored gradient bars per tree row showing size relative to parent
• File age column -- Last modification date, sortable

Interaction

• Context menus -- Right-click anywhere (Tree, Top 50, Diagram): Open in Explorer, Open Terminal, Properties, Copy Path, Copy Size, Move to Trash, Jump in Tree, Scan this Folder
• Keyboard navigation -- Arrow keys to navigate tree, Enter to open files
• Drag & drop -- Drag folders from Finder/Explorer onto the app to scan
• Resizable panels -- Drag to resize tree, diagram, detail panel
• Dark / Light mode -- Toggle with moon/sun button, persists in settings
• 25 languages -- Full i18n with auto-detection and language switcher

Tools

• Find Duplicates -- Detect duplicate files by content hash (xxhash3)
• Trash Recovery -- Browse, restore, or permanently delete trashed files
• Empty Folders -- List empty directories, click to jump to them
• Find Files -- Search by filename pattern in scanned results
• File type filter -- Show only images, video, audio, archives, or PDFs
• Export HTML Report -- Standalone shareable report with stats + chart
• Export CSV/JSON -- Export tree data or raw stats
• Clear Scan -- Reset all results without reloading

Cross-Platform

• macOS -- Universal binary (x86_64 + arm64), Apple Silicon native
• Windows -- NSIS installer, native Windows icons via SHGetFileInfoW
• Linux -- DEB package (Debian/Ubuntu)

Download

Pre-built binaries are available on the Releases page, or grab the latest version directly from the official website: https://www.diskraptor.com.

Platform	Format
macOS	.dmg (signed + notarized) or .pkg
Uninstall	bash installer/uninstall.sh (macOS)
Windows	.exe (NSIS Installer)
Linux	.deb (Debian/Ubuntu)
Website	www.diskraptor.com

Homebrew (macOS & Linux)

Install the cask directly from a local checkout:

git clone https://github.com/SunMe1977/DiskRaptor.git
cd DiskRaptor
brew install --cask ./homebrew/Casks/diskraptor.rb

The cask installs the .dmg (macOS) or .deb (Linux) from the Releases page. You can also download pre-built installers from the official website: www.diskraptor.com.

To install as brew install diskraptor (no tap, no path), the cask must first be merged into the official homebrew/homebrew-cask repository (macOS only) — submit a PR against Casks/d/diskraptor.rb once the macOS .dmg with a fixed SHA256 is published. Linux has no official cask repo.

Build from Source

Prerequisites

• Rust (latest stable) -- curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• Node.js 18+ (for the Tauri CLI)
• Linux: WebKitGTK 4.1 (sudo apt-get install libwebkit2gtk-4.1-dev libgtk-3-dev)

macOS

git clone https://github.com/SunMe1977/DiskRaptor.git
cd DiskRaptor
chmod +x build.sh
./build.sh

Windows

build.cmd

Linux

./build.sh
# Output: dist/DiskRaptor-*.deb

Manual Build (all platforms)

# Build the Tauri app
cd src-tauri
cargo build --release
cd ..

# Build the Windows installer (NSIS)
npx tauri build --bundles nsis --ci

---

Testing

# Rust unit tests (scanner tree, chunking, file accumulators)
cd src-tauri && cargo test

# JS syntax check
for f in frontend/*.js; do node --check "$f"; done

# Full UI test via CDP (requires the app built with the `test-server` feature)
node tests/test_ui.mjs
