While compiling I get this error message from Arduino, does anyone know how to fix it?

Arduino: 1.8.2 (Windows 10), Board: "NodeMCU 0.9 (ESP-12 Module), 80 MHz, Serial, 115200, 4M (3M SPIFFS)"

C:\Users\super\AppData\Local\Temp\Temp1_Wifi-Jammer-master (1).zip\Wifi-Jammer-master\WIFI Jammer\wifi jammer\esp8266_deauther-master\esp8266_deauther\esp8266_deauther.ino:11:18: fatal error: data.h: No such file or directory

#include "data.h"


compilation terminated.

exit status 1
Error compiling for board NodeMCU 0.9 (ESP-12 Module).

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I have my esp-2966 connected through a cable.

You are missing a key library for your board.

Bear in mind that jammers like this are highly illegal.
