I attached an example I did to an Arduino Mega 2560 + sd shield. :slight_smile:

You must save a file into the SDcard (default name "flor1.jpg").

#include <SPI.h>
#include <SD.h>

char* file_name1 = "flor1.jpg";
char* file_name2 = "flor2.jpg";
byte ibuffer[3000];
int ibufferspace = sizeof(ibuffer);
File File1;
File File2;

void setup() {
Serial.begin(19200);
Serial.print("Initializing SD card...");
pinMode(53, OUTPUT);

if (!SD.begin(53)) {
Serial.println("Initialization failed!");
return;
}else {
Serial.println("Initialization done.");
}

File1 = SD.open(file_name1);
if (File1) {
Serial.println("Opening the file: " + String(file_name1) + " done.");
}else {
Serial.println("Error opening " + String(file_name1));
}

if(SD.exists(file_name2)) {
SD.remove(file_name2);
Serial.println("File :" + String(file_name2) + " deleted...");
}

unsigned int previoustime = millis();
if (File1) {
File2 = SD.open(file_name2, FILE_WRITE);
if(File2) {
int i=0;
while (File1.available()>0) {
ibuffer = File1.read();

  • i++;*
  • if (i==ibufferspace) {*
  • File2.write(ibuffer,ibufferspace);*
  • i=0;*
  • }*
  • }*
  • File2.write(ibuffer,i-1);*
  • }*
  • Serial.println("Done copying...");*
  • File1.close();*
  • File2.close();*
  • }*
  • Serial.println("Time: " + String((millis()-previoustime)/1000) + " seg");*
    }
    void loop()
    {
  • // nothing happens after setup*
    }
