Using the Desktop v6 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 difficulty authenticating with your usual 2FA method on macOS, try enabling the Use default browser for authentication setting in the Desktop v6 app from Preferences.
