Started with Budgie. Then discovered Zorin which I am going to stick with.
Problem is that my system looks like this now…

I have tried to use Gparted and KDE partition manager, but it won’t let me delete unused and blank partition.
How do I make my Zorin Partition bigger and remove the partition that is now blank?
You can use GParted and then right click on your Zorin partition & select Resize. 
Vasileios,
Thank you for your reply.
This did not work.
I opened GParted, and when I right click, and get to the menu, it does not allow me to resize or move the partition.
I can create new partitions, but I cannot resize the Zorin partition.
Any other ideas, or suggestions?
Thanks
