What is sync-com.exe?

sync-com.exe is a component of the Sync.com desktop client that coordinates local-to-cloud synchronization. It runs in the background to monitor file system changes and manage network transfers, ensuring your files stay up to date across devices and the cloud.

This process handles delta syncing, conflict resolution, and communication with the Sync.com cloud service. It runs as a separate process to isolate I/O from the UI and uses sandboxed execution to minimize risk.

Quick Fact: The Sync.com client uses sync-com.exe to perform background sync operations, so you may see multiple instances during active syncing.

Types of Sync.com Processes

Sync Engine Process: Core synchronization logic coordinating local changes with the cloud
Watcher Process: Monitors file system changes to trigger sync actions
Background Tasks: Periodic checks, retries, and conflict resolution
Network/API Process: Handles cloud communication and authentication requests
UI Helper: Maintains progress updates and interface state
Telemetry/Logging: Optional data collection and diagnostic logging

Is sync-com.exe Safe?

Yes, sync-com.exe is safe when it is the legitimate file from Sync.com installed via official channels (downloaded from sync.com or packaged with the official client).

Is sync-com.exe a Virus or Malware?

The real sync-com.exe is NOT a virus. Malware may mimic similar names. Always verify the file path and signature.

How to Tell if sync-com.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\Sync.com\Desktop\ or C:\Program Files (x86)\Sync.com\Desktop\. Any sync-com.exe elsewhere is suspicious.
Digital Signature: Right-click the file in Explorer → Properties → Digital Signatures. Should show a signature from Sync, Inc..
Resource Usage: Normal usage is 2-12% CPU per process and 60-250 MB memory; consistently higher usage with no Sync client activity is suspicious.
Behavior: Sync should run when the client is active or during scheduled background sync. If it runs continuously with no UI, investigate further.

Red Flags: If sync-com.exe is located in unusual folders (Temp, AppData, System32), runs when the Sync client isn't installed or updated, has no valid signature, or uses persistent high resources, scan with antivirus and verify with the vendor.

Why Is sync-com.exe Running on My PC?

sync-com.exe runs as part of the Sync.com desktop client to manage local-to-cloud synchronization, monitor file changes, and handle network communications for syncing.

Reasons it's running:

Active Sync in Progress: Files are being uploaded or downloaded; the engine runs to process changes and update cloud copies.
Background Sync Tasks: Scheduled checks, retries, indexing, and conflict resolution occur even when the UI is not active.
Startup Sync: The Sync.com client may be configured to start with Windows, launching sync-com.exe in the background.
File System Monitoring: A watcher monitors folders for changes to trigger incremental sync operations.
Network Connectivity and Retries: Network errors trigger backoff retries to ensure eventual consistency with the cloud.

Can I Disable or Remove sync-com.exe?

Yes, you can disable sync-com.exe. You can pause syncing in the client, disable startup, or uninstall the app if you prefer an alternative solution.

How to Stop sync-com.exe

Pause Sync in Client: Open the Sync.com client and click Pause Sync or disable background syncing in Settings.
Close the Client: Quit the Sync.com application to stop all background processes.
Disable Startup: Task Manager → Startup tab → Disable Sync.com
Stop Background Sync: Settings → General → Turn off 'Continue running background apps when Sync.com is closed'
End sync-com.exe: Open Task Manager → Processes → right-click sync-com.exe → End Task

How to Uninstall Sync.com Client

✔ Windows Settings → Apps → Apps & features → Sync.com → Uninstall
✔ Control Panel → Programs → Uninstall a program → Sync.com → Uninstall
✔ Restart the computer and consider alternatives: OneDrive, Google Drive, Dropbox

Common Problems: High CPU or Memory Usage

If sync-com.exe is consuming excessive resources:

Common Causes & Solutions

Too many files/folders in the sync set: Limit which folders are synced (Selective Sync) and pause syncing for large batches.
Large file uploads/downloads: Schedule heavy sync tasks during off-peak hours or pause while performing such transfers.
Background scanning or indexing: Exclude temp or cache folders from sync; adjust ignore rules in the client.
Outdated Sync client: Update to the latest version from the official site or within the app (Settings → Help).
Conflicts or replays: Check for conflict copies and resolve; ensure versioning is configured correctly.
Antivirus/Firewall interference: Add Sync.com paths to antivirus exclusions and allow network activity for sync-com.exe.

Quick Fixes:
1. Open Sync.com Task Manager (in-app) to identify high-usage items
2. Pause or limit selective sync for problem folders
3. Update to the latest Sync.com client
4. Add Sync.com directories to antivirus exclusions
5. Restart the Sync.com client and re-check resource usage
