Hey there! I can't write text from sd card file to string variable. Can you help me, please? String fileData; File dataFile = SD.open("settings.txt", FILE_READ); while (dataFile.available()){ fileData = fileData + dataFile.read(); } Serial.print(fileData); Thanks!

You still haven't described the problem. What happens, what error messages, etc.
