Filename into a Data type

Im trying to put a file name in a data type like String Files = (“Hello.txt”) so i can delete it with SD.remove(Files). but i keep getting errors how would i put a file name in a data type. here’s my code:

#include <SD.h>
#include <SPI.h>
String Files = "/!1/Hello";
void setup(){
  if (Files.startsWith("/!1/")&& SD.exists(Files)){
	Files.remove(0,4);
	(SD.remove(Files));
  }
}
void loop()
{	
}

how would i put a file name in a data type.

char fileName[] = "/!/Hello";

Of course, then you need to use string manipulation functions, not String methods, but it is better to learn that anyway. Crutches are for cripples.
