Portfolio plugin

Hi, Love your design, and I WILL get it to work!
I’ve just started following you video guides as to setting up Sydney.
I’ve done the Front Page and I’m now trying to follow the instructions to download the portfolio plugin. What I have is a zipfile not an xml and when I try to import it I get the message - data not supported.
What am I doing wrong?

Hello there,

Install plugin manually wp admin > plugins > add new > upload (downloaded zip), here check first video from youtube regarding manual install https://www.youtube.com/watch?v=RQFff6GYSLY
