SD card module with ESP32

I'm using an SD card module with ESP32. My plan is to store configurations such as SSID and passwords.

I tried the function with a text file which contains the text "Hello" and for Serial.write(file.read()); it prints exactly "Hello". But, Serial.print(file.read()); returns 72101108108111. What kind of data type returns read()? I need to convert it into string.

void readFile(fs::FS &fs, const char * path){
  Serial.printf("Reading file: %s\n", path);

  File file = fs.open(path);
  if(!file){
    Serial.println("Failed to open file for reading");
    return;
  }

  Serial.print("Read from file: ");
  while(file.available()){
    //Serial.write(file.read());
    Serial.print(file.read());
  }
  file.close();
}
