Well I thought I had figured it out but I didn’t. I was able to finally shrink a window but when I click on another tab to bring it up it is already shrunk and just goes over top of the other window. I can’t figure out how to have two at the same time. :-(
I open two FileExplorers is when I am moving files around, usually pictures. I shrink them like you did, and then I moved one to the right and one to the left. If you click on the top margin you can move them around.
