Hi @Selbig. Here is a very simple sketch that prints a file from the microSD card to the serial monitor. It might be too rudimentary for your purposes, but thought I would share it here. Notice the line “// SD.remove(“datalog.txt”);” is commented out. Uncomment this line to DELETE the file specified instead of printing it to the serial monitor. I find it is helpful for my work to have this option available when I need it.
