A simple desktop application to analyze and visualize storage usage.

• 🌳 Fast Folder Scanning:
  • Concurrent file system exploration
  • Concurrency level adjustable via SCAN_CONCURRENCY environment variable (Default: Half of logical CPUs)
  • Correctly handles Symlinks and Windows Reparse Points (Junctions) to prevent infinite loops and incorrect size calculations
• 📊 Detailed Information Display:
  • File/Folder name
  • Size (automatic unit conversion)
  • Percentage of total usage (percent display + bar graph)
  • File count
• 💾 Physical Disk Size Calculation:
  • Toggle "Calculate Size on Disk" to measure actual disk usage
  • Accounts for sparse files, compression, and filesystem block allocation
• 📋 Sorting: Sort by any column (name, size, percentage, file count)
• 🔄 Refresh: Rescan to reflect the latest folder structure
• 📂 Open File: Double-click to open files/folders in the OS default application
• ⚠️ Error Handling: Visualization of inaccessible folders

Go to the Releases page and download the executable for your operating system.

This application uses the Wails framework.

• Frontend: Svelte + Vite (HTML/CSS/JS)
• Backend: Golang (System calls, File operations)
• Communication: Wails runtime (Frontend-Backend binding)
