A high-speed, multithreaded file transfer utility for Windows — a modern GUI for robocopy-style operations
VelocityFS brings the raw speed of native multithreading to a beautiful, modern "Elevated Flat Dark" UI.
- Parallel Multithreaded Engine: Copy or move files exponentially faster by utilizing all available CPU cores.
- SHA-256 Checksum Verification: Optional cryptographically secure verification ensures your files arrive 100% intact.
- Robust Retry Logic: Network blip? Locked file? The engine automatically retries failed transfers.
- Exclude Filters: Easily skip unwanted files and directories (e.g.,
*.tmp,node_modules). - Live Speed Sparkline: Monitor your transfer throughput (MB/s) in real-time with a sleek, GPU-accelerated polyline graph.
- Per-File Progress: Keep tabs on exactly what is being copied and verify individual file success directly in the UI.
- Drag-and-Drop: Seamlessly drag folders from Windows Explorer directly into the Source or Destination inputs.
- Pause & Resume: Suspend active transfers at any time without losing your progress.
- System Tray Integration: Minimize the app to the Windows tray during long transfers to keep your taskbar clean.
- Toast Notifications: Get native Windows balloon notifications when your massive file dumps finally complete.

- Head over to the Releases page.
- Download the latest
VelocityFS-Setup.exe. - Run the installer to easily add the app to your Program Files and Start Menu.
If you prefer to compile the application yourself, you will need the .NET 8 SDK. (If you also want to compile the setup wizard yourself, see BUILDING_INSTALLER.md).
# 1. Clone the repository
git clone https://github.com/YOUR_USERNAME/VelocityFS.git
# 2. Navigate to the project directory
cd VelocityFS
# 3. Restore dependencies
dotnet restore
# 4. Build the project
dotnet build -c Release
# 5. Run the application
dotnet run -c Release- Select Directories: Use the "Browse" buttons or simply Drag-and-Drop folders into the SOURCE and DESTINATION text boxes.
- Set the Mode: Choose between
Copy(leaves original intact) orMove(deletes original after a successful transfer). - Configure Threads: Set the number of concurrent threads. This defaults to your CPU's core count for maximum throughput.
- Verify Checksums: Check this box if you are transferring highly sensitive data and want cryptographic proof that the copy matches the original byte-for-byte (Note: this will slow down the overall transfer time).
- Start: Click
START TRANSFER. You can monitor live speeds via the sparkline, check per-file progress in the list view, or hitPAUSEat any time.
- Framework: .NET 8.0
- UI: Windows Presentation Foundation (WPF)
- Language: C# 12
- Design System: Custom "Elevated Flat Dark" resource dictionary featuring JetBrains Mono and Inter typography.
