You drag and drop.


If you want a program to do that, that's no problem as long as you know the directory that the flash drive will make (F: is the drive name on my machine and probably most people's). From there, it's just a matter of using ofstream.

#include <fstream>

int main()
{
	std::ofstream outFile;
	outFile.open("F:\\Racism.txt");
}

EDIT: If you also want to copy a file, here's some simple code I found to do it:

#include <fstream>

int main()
{
	std::ifstream  inFile("Racism.txt", std::ios::binary);
	std::ofstream  outFile("F:\\Racism.txt", std::ios::binary);

	outFile << inFile.rdbuf();
}

You can do that with the filesystem library in C++ 17.

#include <iostream>
#include <string>
#include <filesystem>

int main() {
  std::string fn;
  std::string cpLoc;
  std::cout << "Enter filename to be copied: ";
  std::getline(std::cin, fn);
  if(!std::filesystem::exists(fn)) {
    std::cerr << "Error: " << fn << " file does not exist\n";
    return 1;
  }
  std::cout << "Copy to where: ";
  std::getline(std::cin, cpLoc);
  if(!std::filesystem::exists(cpLoc)) {
    std::cerr << "Error: the directory does not exist\n";
    return 1;
  }
  std::filesystem::copy(fn, cpLoc);
  return 0;
}

Hi and thank you for the responses... but I have found a way on youtube that does what i want to do. here is the link:

with this I can run a program(console) from a usb drive.. I would like to know if I can put this runnable program/folder from the USB drive and copy and paste it to a computer desktop and run it that way

thanks again

Why don't you try? It should just work, as long as you're going from Windows to Windows. (And if you're building a 64-bit exe, then that can't be run on a 32-bit system).

If it complains about a runtime redistributable being needed, that might need to be installed.

tried it, Ganado, it worked, thank you, copied and pasted it
