Merkle

A Windows desktop application for analyzing disk space usage and finding duplicate files. Built with WinUI 3.

   

What It Does

• Scan folders to collect file metadata (paths, sizes, timestamps, SHA-256 hashes)
• Detect duplicate files using cryptographic and perceptual hashing
• Identify duplicate images even if they're slightly different (supports .jpg, .png, .bmp, .gif, .webp, .tiff)
• Analyze disk usage with file type distribution and large file detection (>256 MB)
• Delete duplicates safely while keeping the oldest copy and removing empty folders

100% local processing - No data collection, no internet required, no cloud services.

Tech Stack

• .NET 8 + WinUI 3 (Windows App SDK 1.5)
• SixLabors.ImageSharp for image processing
• CoenM.ImageSharp.ImageHash for perceptual hashing
• PowerShell scripts for file system operations

How to Use

1. Scan Folder → Browse to a folder and scan it
2. Compute Image Hashes → Optional, for detecting duplicate images
3. Analyze Scan Results → View statistics, duplicates, large files
4. Delete Duplicates → Safely remove duplicate files

Results are saved to .merkle files in a .merkle folder inside the scanned directory.
