Saving from 2018 for x7

Hi all!

I'm currently at my daughter's in Maine. I needed to work on something so I downloaded the trial version of coreldraw graphics suite 2018 because it was the only only one I could find (onto my daughter's desktop computer) Tomorrow we will be driving across from Maine to my home in Michigan. So just now I was going to save my stuff and put it on a flashdrive. It doesn't give x7 as an option.. It has:

Version 20.0 (2018)

Version 19.0 (2017)

Version 18.0

Version 17.0

Version 16.0

Version 15.0

Version 14.0

Version 13.0

Version 12.0

Version 11.0

I remember like 10 years ago needing to save as a different one from what I had at work and at home. But it's been ages, and they were titled easier

And yes I also plan to save in other formats too

THANKS, ~Lisa
