const Exist = require('./exist');
const Mkdirs = require('./mkdirs');

const WriteFile = Util.promisify(Fs.writeFile);

	const folderPath = Path.dirname(path);

	await Mkdirs(folderPath, options.mode);

	const exist = await Exist(path);

	if (exist === false) {
		await WriteFile(path, data, options);
