I was getting started with tutorial – “ESP32: Guide to MicroSD Card Module using Arduino IDE”. When I attempted to compile and upload the sketch from the tutorial, it returned the following error message:

This looks like a previous compile error with a differnt project; however that was resolved with a correction in the used library User_Setup file was not placed in the correct folder??????????
