Deduplicator

This is my first C# mini project, built as a CLI tool for finding and removing duplicate files.
The project is still small, but I plan to gradually extend and improve it as I learn more about C# and .NET.

Built on .NET 10 and tested on Fedora Linux.

What does it do?

Scans a directory, detects duplicate files, and lets you safely remove them after confirmation.

How it works

Even though this is a beginner project, it already uses some solid concepts:

• Funnel-style algorithm: files are grouped by size first, then compared using SHA-256 hashes
• Asynchronous file processing to avoid blocking and reduce memory usage
• Console UI powered by Spectre.Console (tables, progress bars)
• Immutable data models using C# record types

Installation & Run

Requires .NET 10 SDK.

git clone https://github.com/1Filipek2/deduplicator-mini
cd Deduplicator.Cli
dotnet run
