RoboSync: a friendly Robocopy GUI for Windows

RoboSync is a free, open-source desktop app that puts a clean graphical interface on top of Robocopy, the robust file-copy engine built into Windows. It keeps Robocopy’s speed and reliability while removing the need to memorise command-line switches, so copying, mirroring, moving and syncing folders becomes a point-and-click task.

What it does

Robocopy is one of the most dependable tools on Windows for moving large amounts of data, but its many flags make it intimidating and easy to get wrong. RoboSync wraps it in a modern desktop interface: you pick a source and a destination, choose an operation mode, set any advanced options, and the app builds and runs the correct Robocopy command for you while streaming progress back in real time.

Key features

• Four operation modes: copy, mirror, move and sync.
• Native folder pickers for source and destination, with input validation and a confirmation step before any destructive operation.
• Advanced options: include subfolders, retry counts, multithreading, permission preservation, and file or folder exclusion patterns.
• Dry-run preview, so you can see exactly what would happen before touching any files.
• Live progress streaming with current file, file and byte counts, elapsed time and ETA, plus Start, Pause/Resume, Cancel and Rerun controls.
• Color-coded logging shown in the UI and written to timestamped log files on disk.
• Save and reload job configurations as readable JSON files.
• A real-time, copy-paste-ready preview of the exact Robocopy command being run.

Built with

RoboSync is written in C# on .NET 8, using WPF with an MVVM architecture. It drives the native Robocopy.exe under the hood, persists job configurations with System.Text.Json, and ships with a xUnit test suite. The packaged build is a standalone executable, so end users do not need the .NET SDK installed.

Requirements

• Windows 10 or Windows 11.
• .NET 8 SDK, only for building from source; the packaged executable runs without any .NET installation.
