I have found this tutorial for the ESP8266, but I think it should translate easily to the ESP32 with the corresponding libraries : https://tttapa.github.io/ESP8266/Chap12%20-%20Uploading%20to%20Server.html A demo sketch using SD storage for the ESP32 is also available here : https://github.com/espressif/arduino-esp32/blob/master/libraries/WebServer/examples/SDWebServer/SDWebServer.ino I'm not sure to understand what your issue is with getting a variable out of a text file. Could you explain what you mean or what you're trying to accomplish ?
