How to import .zip file

Hi, I am new to Kolibri and I have a .zip file of Kolibri code-named

I am not able to figure out how do I import it in my new server as out of 3 options none of them allow to import .zip file

Below I have attached the content of the .zip file. Need advice on how to import these files into my new server.

Any advice or help is appreciated!
Thank you.
