 You can write to file in a subfolder by specifying a similar text using small letters in the path.
 Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".
 
+*SD card folders:*
+
+If you place a file auto<0-9>.g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu.
+First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.

 *Endstop trigger reporting:*
 
 If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port.
