If I use Arduino IDE and Serial.println(__FILE__) I get the full pathname. If I use platformio I get src/main.cpp. AFAIK the first is the correct behaviour – and the second is pointless. Am I missing something?

FILE always returns src/main.cpp (Arduino ESP8266)

Thank you all for the information.

I shall continue (remembering to) enter the pathname as a litteral - and escaping as required.

And I guess that is where it ends.
