		filesize: data.length,
		checksum: crypt.createHash('md5').update(data).digest('base64'),
	};

	// first i send header
	client.write(JSON.stringify(header));

	// then i send data buffer
	// Sending success If filesize still in KB or less than 20MB
	client.write(data);

	// And i want a technique like fs.createReadStream(_this.locationPath+_this.header.filename).pipe(client);
	// but come from buffer directly.. hmmm something like coolMethod(myExistingBuffer).pipe(client);
