Usage

From source file:Main.java

public static void CopyFile(String source, String destination) throws IOException {
    FileInputStream fin = new FileInputStream(source);
    FileOutputStream fout = new FileOutputStream(destination);

    byte[] b = new byte[1024 * 1024];
    int noOfBytes = 0;

    while ((noOfBytes = fin.read(b)) != -1) {
