SyncTrayzor Download, Features, Setup, and Alternatives (2026 Guide)

You have two Windows PCs, and the file you need is always on the other one. SyncTrayzor fixes that without sending your files to a cloud company. It is a free Windows tray app that wraps Syncthing, a private, open-source file sync tool.

This guide covers what SyncTrayzor does, where to download it safely, how to set it up, and what to do when sync stops working. It also covers the alternatives.

What Is SyncTrayzor?

SyncTrayzor is a Windows tray utility that runs Syncthing and gives it a desktop-friendly wrapper. It launches Syncthing in the background, shows a tray icon, and displays the Syncthing interface in its own window.

What Does SyncTrayzor Do?

• Starts Syncthing automatically when Windows starts.
• Keeps it running quietly from the system tray.
• Shows sync status, notifications, and a conflict resolver.

It does not sync files by itself. Syncthing does the actual work.

What Is Syncthing Used For?

Syncthing keeps folders identical across devices, directly and privately. Files move between computers without passing through a company server. Read more in the official Syncthing documentation.

How SyncTrayzor and Syncthing Work Together

Think of Syncthing as the engine and SyncTrayzor as the dashboard. If SyncTrayzor closes, it shuts Syncthing down with it.

Who Should Use SyncTrayzor?

• Windows users who want a simple tray-based sync tool.
• People who prefer not to use the command line.
• Anyone who wants private sync with no subscription.
• Home and small-office users with a few devices.

Is SyncTrayzor Still Maintained?

Development continues in a fork. Its latest release, version 2.2.0, upgrades to .NET 10 and Chromium (CEF) 146, and improves the conflict resolver and the upgrade path from version 1.

SyncTrayzor Features

SyncTrayzor inherits most of its power from Syncthing and adds Windows conveniences on top.

File and Folder Synchronization

Pick a folder and a device, and both sides stay matched. New files, edits, renames, and deletions all carry over.

Automatic and Real-Time Sync

Syncthing watches folders and sends updates within moments, with a scheduled full rescan as a safety net. No sync button needed.

Two-Way (Bidirectional) Sync

Edit a file on PC A and it updates on PC B, and the reverse. Set a folder to Send Only or Receive Only for one-way flow.

Sync Across Multiple Computers

Each folder has its own device list, so one folder can sync laptop to desktop while another syncs desktop to a home server.

Shared Folders and Access Control

For every folder, you choose which devices may access it.

Windows System Tray Integration

This is the main selling point. The tray icon shows status at a glance, the app can start with Windows, and balloon notifications tell you when sync finishes.

Syncthing Management

Folder paths, devices, versioning, and ignore patterns live in the Syncthing interface that SyncTrayzor displays. SyncTrayzor adds its own startup and notification options.

SyncTrayzor vs. Syncthing

Short answer: Syncthing is the sync engine. SyncTrayzor is a Windows wrapper around it.

Syncthing Core vs. SyncTrayzor Interface

When Should You Use SyncTrayzor Instead of the Web Interface?

Choose SyncTrayzor for a set-it-and-forget-it Windows experience. Choose plain Syncthing if you use several operating systems, run a headless server, or want the smallest footprint.

Can SyncTrayzor Work Without Syncthing?

No. It launches and manages Syncthing, so it cannot sync files on its own.

How File Synchronization Works

The Basic Idea

Each device has a unique Device ID. Exchange IDs, approve the connection on both sides, then share folders. Syncthing finds the other device and starts matching files.

Syncing Between Two Computers

1. Install SyncTrayzor on both PCs.
2. Add each PC’s Device ID to the other.
3. Share a folder from one PC.
4. Accept the folder on the second PC and choose where to store it.

Syncing Across Many Devices

Add every device to every other device it should talk to, then share each folder only with the devices that need it. A few well-planned folders beat many scattered ones.

How Devices Find Each Other

Syncthing uses local discovery on your home network, plus global discovery servers and relays across networks. File data is encrypted in transit, and relays only pass along encrypted traffic.

SyncTrayzor Download, Installation, and Setup

How to Download SyncTrayzor

Download only from the project’s official GitHub releases page. Random “free download” sites sometimes bundle unwanted software.

• Installer (an .exe setup file)
• Portable (a .zip you unzip and run)

Pick the 64-bit build on a modern PC.

Is SyncTrayzor Free?

Yes. SyncTrayzor and Syncthing are both free and open source, with no licenses to buy. Syncthing uses the Mozilla Public License 2.0.

How to Install SyncTrayzor on Windows

1. Download the installer from the official release page.
2. Run the setup file.
3. Follow the prompts and finish the install.
4. Launch SyncTrayzor from the Start menu.

On first launch it starts Syncthing and opens the interface.

Initial Configuration

You will see Syncthing’s “Default Folder.” Keep it, change its path, or remove it. Then set a GUI password in Syncthing’s settings so nobody else on the PC or network can change your setup.

Handy SyncTrayzor Settings

• Start on login: syncing resumes after reboot.
• Start minimized: runs quietly in the tray.
• Notifications: choose what you hear about.
• Close to tray: closing the window will not stop syncing.

How to Use SyncTrayzor

How to Add a Folder

1. Open the main window.
2. Click Add Folder.
3. Choose a label and the folder path.
4. On the Sharing tab, tick the devices that should receive it.
5. Save.

How to Add a Remote Device

1. On PC B, find its Device ID in the Actions menu.
2. On PC A, click Add Remote Device.
3. Paste PC B’s ID and give it a name.
4. Save, then accept the request on PC B.

How to Share a Folder Between Computers

Once devices are connected, edit the folder and select the second device on the Sharing tab. Accept the prompt on the other PC, choose a destination, and the initial sync begins.

How to Monitor Sync Status

The tray icon and main window show states like “Up to Date,” “Syncing,” or “Out of Sync.” Click a folder to see file counts and remaining data.

How to Pause or Resume Sync

Pause a single folder, a single device, or everything. This helps on metered connections or during large copies.

Managing Multiple Devices and Folders

Use clear labels like “Work-Docs” or “Photos-Archive” so five or six folders stay easy to tell apart.

Syncthing Configuration Through SyncTrayzor

Folder Types

File Versioning and Conflict Handling

Versioning keeps older copies of changed or deleted files. Options include Trash Can, Simple, and Staggered.

A conflict happens when the same file is edited on two devices before they sync. Syncthing keeps both copies and labels one “sync-conflict.” SyncTrayzor’s conflict resolver helps you compare and choose.

Ignore Patterns

An ignore file lists what you don’t want to sync, such as temp files, thumbnail caches, and node_modules folders. Patterns are set per folder in a file named .stignore.

Connection and Network Settings

The default sync port is 22000. If devices struggle to connect across networks, check that your firewall allows Syncthing and that discovery and relay options are on. You can also set bandwidth limits.

Advanced Options

Rescan intervals and permission handling are available, but the defaults suit most people.

SyncTrayzor Portable and Desktop Usage

Is SyncTrayzor Portable?

Yes. Unzip the portable build to any folder, including a USB drive, and run SyncTrayzor.exe. Its data folder stores your settings, so copy it when updating.

Running From the System Tray

You rarely need the main window. The tray icon opens the interface, pauses sync, or exits.

Windows Compatibility

SyncTrayzor Troubleshooting

SyncTrayzor Is Not Working

1. Exit SyncTrayzor fully from the tray.
2. Restart it.
3. Update to the latest release.
4. Make sure only one copy is running. Recent versions refuse to start when two copies from different folders share one config.

Config Version Errors

A message saying the config file is newer than supported usually appears when a standalone Syncthing was run before SyncTrayzor. A commonly reported fix is deleting the Syncthing folder in AppData\Local and restarting SyncTrayzor.

Devices Are Not Connecting

• Confirm both devices are running.
• Double-check the Device IDs.
• Allow Syncthing through the Windows firewall.
• Make sure both sides approved the connection.

Folders Are Not Synchronizing

• Check whether the folder is paused.
• Read the “Out of Sync” details.
• Confirm there is enough free disk space.
• Check that the shared folder path exists.

Sync Is Stuck or Slow

Large first-time syncs take a while because every file is scanned and hashed. Slow disks and weak Wi-Fi are common causes, and a wired connection helps.

How to Restart or Reset

Exit from the tray menu, then reopen. For a full reset, back up your data folder first, then clear the configuration and set up devices again.

Safety, Privacy, and Reliability

Is SyncTrayzor Safe?

When downloaded from the official GitHub page, it is considered safe. It is open source, so anyone can inspect the code.

Is Syncthing Safe for Syncing?

Syncthing encrypts device-to-device traffic with TLS and authenticates connections using device IDs. Only devices you approve can connect.

Best Practices

• Set a strong GUI password.
• Only share folders with devices you trust.
• Keep SyncTrayzor and Syncthing updated.
• Turn on versioning for important folders.
• Keep a separate backup for anything irreplaceable.

SyncTrayzor for Different Needs

A freelancer might sync a “Projects” folder between a desktop and a laptop. Someone else might mirror photos to a home server for safekeeping.

If your work also involves PDF preparation, read about tools like Enfocus PitStop Pro, then use sync to share finished files between your own computers.

SyncTrayzor Review

Ease of use: Good once set up. Pairing takes a few minutes, then daily use is nearly invisible.

Performance: Fast on local networks and reliable online. Initial scans of large folders are slow.

Windows integration: Strong. The tray icon, startup option, and notifications are the main draws.

Pros and Cons

Who Is It Best For?

Privacy-minded Windows users who want automatic sync without a subscription.

Best SyncTrayzor Alternatives

How to Choose

1. Do I need privacy or convenience?
2. Do I need a web link to share files?
3. Do I use more than just Windows?

For privacy and control, choose Syncthing or SyncTrayzor. For easy sharing with other people, a cloud service may suit you better.
