Why are there 3 files here? Shouldn’t there only be a firmware update and a touchscreen firmware update? What’s the third file?

The youtube tutorial above only mentions two files.

Hi,
The first one isbfor the touchscreen. Uou havebto unzip it and drap and drop the all files in a micro sdcard before to flash the touchscreen.
The next ttwo are the same file. Choose one and drag and drop it to the same sdcard before to flash it.
Cheers
