# Example

#include <experimental/filesystem>
#include <fstream>
#include <iostream>
namespace fs = std::experimental::filesystem;
 
int main()
{
    fs::create_directories("sandbox/dir/subdir");
    std::ofstream("sandbox/file1.txt").put('a');
    fs::copy("sandbox/file1.txt", "sandbox/file2.txt"); // copy file
    fs::copy("sandbox/dir", "sandbox/dir2"); // copy directory (non-recursive)
    // sandbox holds 2 files and 2 directories, one of which has a subdirectory
    // sandbox/file1.txt
    // sandbox/file2.txt
    // sandbox/dir2
    // sandbox/dir
    //    sandbox/dir/subdir
    fs::copy("sandbox", "sandbox/copy", fs::copy_options::recursive);
    // sandbox/copy holds copies of the above files and subdirectories
    fs::remove_all("sandbox");
