Using the Desktop App, you can view the realtime logging if the Show Logging option is enabled in Settings or Preferences. Enabling this will display the logs at the bottom of the app's UI. You can also set the logging level, such as Info or Debug, from the same window.

On Windows, you can view the logs by browsing to %UserProfile%\AppData\Roaming\Files.com\v6\Desktop-v6.log.

On macOS, you can view the logs by navigating to ~/Library/Logs/Files.com/v6/Desktop-v6.log.

Problems with 2FA Methods

If you are having trouble authenticating with your usual 2FA method, try enabling Use default browser for authentication in the Desktop App under Preferences on macOS or Settings on Windows.
