Is it a Virus?
NO - Safe
Must be in C:\Program Files\Seafile\Seafdav\seafdav.exe
Can I Disable?
YES - It will stop WebDAV access
Disabling seafdav will stop WebDAV access to Seafile libraries and may prevent mounting via WebDAV.
What is seafdav.exe?
seafdav.exe is the WebDAV server component of the Seafile Server. It enables clients to mount Seafile libraries as network drives via WebDAV, handling authentication, file operations, and synchronization with the backend. It runs as a background service paired with the main Seafile daemon.
This WebDAV service translates standard WebDAV requests into Seafile backend operations, enabling file read/write and synchronization while enforcing Seafile permissions and versioning.
Quick Fact: WebDAV support allows cross‑platform access to libraries from Windows, macOS, and Linux clients without requiring the Seafile client installed on every device.
Types of Seafdav Processes
- WebDAV Service: Handles WebDAV requests and maps them to Seafile libraries
- Daemon Process: Runs as a background service coordinating Seafile components
- Auth & Sync Listener: Manages authentication and change syncing from WebDAV clients
- Network Listener: Listens on the WebDAV port for incoming connections
- Background Tasks: Parses requests and interacts with Seafile backend
Is seafdav.exe Safe?
Yes, seafdav.exe is safe when it's the legitimate file from Seafile downloaded from official sources (seafile.com or the packaged Seafile Server).
Is seafdav.exe a Virus or Malware?
The real seafdav.exe is NOT a virus. Malware sometimes disguises itself with similar names to trick users.
How to Tell if seafdav.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Seafile\Seafdav\seafdav.exe or C:\Program Files (x86)\Seafile\Seafdav\seafdav.exe. Any seafdav.exe elsewhere is suspicious.
- Digital Signature:: Right-click seafdav.exe in Windows Explorer → Properties → Digital Signatures. Should show "Seafile GmbH".
- Resource Usage:: Normal usage is 2-12% CPU and 60-180 MB memory. Persistent high usage when idle is suspicious.
- Behavior:: Seafdav.exe should start with the Seafile Server and respond to WebDAV requests only when configured. If it runs without the server, investigate.
Red Flags: If seafdav.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when Seafile isn't active, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "seafdav.exe" in untrusted locations.
Why Is seafdav.exe Running on My PC?
seafdav.exe runs when the Seafile WebDAV service is active, or when WebDAV is enabled in Seafile Server configuration. It may stay alive to serve requests from WebDAV clients.
Reasons it's running:
- Active WebDAV Access: A WebDAV client has connected and is performing file operations against Seafile libraries.
- Background Sync: Seafile’s backend syncing is active to push or pull changes for mounted libraries.
- Startup Configuration: Seafile Server or the WebDAV component is configured to start automatically on system boot.
- Maintenance or Updates: Server maintenance tasks or updates may trigger Seafdav to start or remain running during maintenance windows.
- Multiple Clients: Several WebDAV clients mounting different libraries can keep seafdav.exe active to serve them concurrently.
Can I Disable or Remove seafdav.exe?
Yes, you can disable seafdav.exe. Doing so will disable WebDAV access to Seafile libraries; other Seafile client functionality remains unaffected, but remote mounting via WebDAV will be unavailable.
How to Stop seafdav.exe
- Stop WebDAV Service: In Windows, open Services and stop the Seafile WebDAV service (or seafdav) if listed.
- Disable Startup: In Services, set the Seafile WebDAV service startup type to Disabled so it doesn't start on boot.
- Restart Seafile Server: Restart the Seafile Server to apply changes.
- Verify Status: Check Task Manager for absence of seafdav.exe and attempt a WebDAV mount to confirm it's disabled.
- Update Configuration: If you use Seafile Server config files, set WebDAVEnabled=false in seafdav.conf and reload services.
How to Uninstall Seafdav
- ✔ Windows Settings → Apps → Seafile Server → Modify (or Uninstall WebDAV component if available)
- ✔ Control Panel → Programs → Uninstall a program → Seafile Server → Uninstall
- ✔ Note: Uninstalling may remove libraries if not backed up; ensure backups or reconfigure installation
Common Problems: High CPU or Memory Usage
If seafdav.exe is consuming excessive resources or behaving unexpectedly:
Common Causes & Solutions
- Excessive Open WebDAV Clients: Limit the number of connected WebDAV clients; consider disabling unused mounts
- Large File Operations: Large file uploads/downloads can spike CPU; schedule heavy transfers during off-hours
- Misconfigured WebDAV Port: Check seafdav.conf and ensure the port binding is correct and not conflicting with other services
- Outdated Server: Update Seafile Server to the latest version that includes WebDAV performance fixes
- Resource Leaks: Investigate and apply patches; monitor memory usage with system tools
- Malicious Extensions or Clients: Disconnect suspicious WebDAV clients; ensure client software is from trusted sources
Quick Fixes:
1. Quick Fixes:
2. 1. Use a WebDAV client manager to identify active connections; disconnect unnecessary clients
3. 2. Restart Seafile Server to reset WebDAV state
4. 3. Review seafdav.conf for misconfigurations and incorrect port bindings
5. 4. Ensure antivirus exceptions allow Seafile's WebDAV components
6. 5. Check for updates to Seafile Server that address WebDAV performance
Frequently Asked Questions
Is seafdav.exe a virus?
No, the legitimate seafdav.exe from Seafile is not a virus. Verify the path C:\Program Files\Seafile\Seafdav\seafdav.exe and the digital signature from Seafile GmbH.
What is seafdav.exe?
seafdav.exe is the WebDAV server component of Seafile Server. It exposes Seafile libraries to WebDAV clients, enabling mounting as network drives.
Can I disable seafdav.exe?
Yes, you can disable seafdav.exe. It will stop WebDAV access to your libraries; you can still use the standard Seafile clients.
What port does seafdav.exe listen on?
The WebDAV port is configured in seafdav.conf. Check the port setting there and ensure it doesn't conflict with other services; the default port is defined by your Seafile Server configuration.
Why does seafdav.exe stay running after closing the Seafile client?
Seafdav.exe stays running to serve WebDAV requests and to keep mounted libraries accessible. It runs as a service or daemon alongside the Seafile Server.
How do I enable WebDAV after disabling?
To re-enable WebDAV, ensure WebDAV is enabled in Seafile Server config, then start the Seafile WebDAV service or daemon again and retry mounting via WebDAV.
