fs.access(dir, fs.constants.F_OK, (err) => {
    if (err) {
      if (err.code === 'ENOENT') {
        fs.mkdir(path.join(__dirname, dir), {}, (mderr) => {
            if (mderr) throw mderr;
            console.log(`Folder ${dir} created`);
        });
      }  
    } else {
        console.log(`${dir} exists`);
