CoreSync Data Synchronization Client
coresyncclient.exe is safe. It's CoreSync's official background client that synchronizes data and settings across devices, running with minimal resources when idle.
coresyncclient.exe is the CoreSync client executable that runs on Windows to sync data, preferences, and files across devices tied to your CoreSync account. It runs quietly, performing incremental updates, conflict resolution, and secure communication with CoreSync servers to ensure consistency.
This multi-threaded background service uses a persistent connection to the CoreSync cloud, handles delta syncing, and maintains a local cache. It spawns worker threads for network I/O and file indexing to avoid blocking the user interface.
Quick Fact: CoreSync pioneered real-time cross-device syncing with efficient delta updates and conflict resolution built into the client since early versions.
Yes, coresyncclient.exe is safe when it's the legitimate file from CoreSync downloaded from official sources (coresync.com or official app store components).
The real coresyncclient.exe is NOT a virus. However, malware sometimes disguises itself using similar names to trick users.
C:\Program Files\CoreSync\coresyncclient.exe or C:\Program Files (x86)\CoreSync\coresyncclient.exe. Any coresyncclient.exe elsewhere is suspicious.Red Flags: If coresyncclient.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when you're not initiating a sync, has no digital signature, or uses excessive resources constantly, scan with antivirus immediately. Beware of similarly-named files like "coresyncclient_main.exe" or "coresyncd.exe" from untrusted sources.
coresyncclient.exe runs to keep data synchronized across devices and to apply configuration changes from CoreSync servers.
Reasons it's running:
Yes, you can disable coresyncclient.exe. If you don't need CoreSync syncing, you can disable auto-start and close the app to stop background activity.
If coresyncclient.exe is consuming excessive resources:
Quick Fixes:

No, the legitimate coresyncclient.exe from CoreSync is not a virus. Ensure the file path is C:\Program Files\CoreSync\coresyncclient.exe and that the digital signature shows CoreSync Ltd.
CPU usage occurs during active syncing or when indexing data. If it stays high when idle, check sync tasks, disable non-critical devices, and verify no malware is present.
Typically at C:\Program Files\CoreSync\coresyncclient.exe or C:\Program Files (x86)\CoreSync\coresyncclient.exe.
Yes. Disable startup in Task Manager, exit from the system tray, or turn off auto-sync in the CoreSync settings.
Windows Settings → Apps → Apps & Features → CoreSync → Uninstall. Reinstall if needed or switch to another sync tool.
CoreSync is a cross-device data synchronization platform that keeps files, settings, and preferences in sync across your devices via a cloud service.
