Troubleshooting kDrive issues (antivirus, firewall, etc.)

Update 09/15/2026

This guide explains how to troubleshoot access or usage issues with kDrive on Windows and macOS when third-party software may be interfering with your synchronization.

 

Introduction

  • The kDrive application may sometimes encounter interaction issues with Windows or macOS firewalls, as well as with certain antivirus, VPN, or cleanup solutions, which can lead to file synchronization difficulties, prevent PDFs from opening on the web, or make it impossible to use Lite Sync mode (on-demand files).
  • It is necessary toallow kDrive within these applications and add the following three essential components to the whitelist:
    1. kdrive.exe (or kdrive.app on macOS)
    2. kdrive_client.exe
    3. The domain *.infomaniakusercontent.com
  • If you are experiencing a synchronization issue and missing folders, please refer to this other guide.
