Host Agent

Runs on the destination computer. Generates unique Sync Keys (GFS-XXXX-...), listens for incoming file pushes, manages target directories, and keeps destination folders completely updated.

  • Multi-folder and multi-key management
  • In-GUI password reset (no old password required)
  • Real-time "Last Sync" timestamp auto-refresh
  • Standalone Win32 native executable (no install required)

Client Manager

Runs on the source computer. Stores your configured sync pairings, maps directly to the host across LAN or internet, and triggers 100% exact mirror pushes with a single click.

  • One-click "Push & Sync" mirror execution
  • Pairings dashboard with custom friendly labels
  • Delta transfer — skips unmodified files automatically
  • Exact mirror pruning (cleans deleted files on host)

How It Works in 3 Simple Steps

Synchronize any local directory to any remote destination folder with zero configuration hassle.

1

Add Folder on Host

Open GroupDraft-SyncHost.exe, click Add Folder, select your target destination directory, and choose a password. A unique 16-character Sync Key is generated automatically.

2

Pair on Client

Open GroupDraft-SyncClient.exe, click Add Pairing, paste the Sync Key, and pick the local folder you wish to push. Give it a friendly label to easily identify it.

3

1-Click Mirror

Click Push & Sync, enter your password, and client syncs everything. Modified files are updated, identical files are skipped, and obsolete files are pruned for 100% exact parity.

Engineered for Reliability, Speed & Security

All components are designed natively for Windows with zero external runtimes or framework dependencies.

100% Exact Mirroring

The destination folder on the host reflects 100% of the client folder. New and updated files are written atomically via temp files, and files deleted from the client are safely removed from the host.

SHA-256 Delta Transfer

Both sides compute fast chunked SHA-256 hashes. Only files that have actually been created or changed are transferred across the network, saving massive bandwidth and time.

In-Transit TLS 1.3 Encryption

All network communication is end-to-end encrypted with TLS 1.3 / AES-256-GCM using ephemeral elliptic-curve certificates. Password verification uses salted SHA-256 challenge-response proofs.

Windows DPAPI At-Rest Protection

Passwords stored in host configuration files are encrypted using native Windows DPAPI (CryptProtectData) tied to the Windows user account. Passwords are never stored in plaintext.

Multi-Key & Multi-Folder Routing

A single Host instance can host multiple sync keys for different projects, clients, or team members, each mapping securely to its own designated destination folder.

Direct P2P (LAN & Direct WAN)

Connects directly peer-to-peer over local network (with instant auto-discovery) or across the internet via automatic UPnP router port mapping, with zero manual router configuration or cloud file storage.
