How to Modify the Configuration File

Modifying the Configuration File After Burning

• The configuration items that are only effective on the first startup must be modified by using a professional text editor to open the configuration file config.txt in the removable disk FlyOS-Conf after burning.

Online Configuration Modification While System is Running

• For ordinary configuration items, modifications made in the system's web configuration page will take effect after restarting the system.

  • Open the device IP address in the browser, for example: 192.168.1.2/
  • In fluidd, uncheck as shown on the left side of the figure -> "Filter hidden files and folders".
  • In mainsail, check as shown on the right side of the figure -> "Show hidden files".
  • At this point, you can see the .flyos-config folder. Enter this folder to find the sys-config.conf file.
  • The sys-config.conf file is a symbolic link to the configuration file config.txt in the removable disk FlyOS-Conf.
  
  • Open the sys-config.conf file, make the necessary modifications, save and close it, then restart the system.
  
  • Note: The format of the configuration items in the sys-config.conf file is key=value, do not change it to key: value.
  • After saving the modifications, restart the system for changes to take effect.
