documents, downloads, etc. folders open in full page

My download, documents, pictures, etc. folders opened in small pages on desktop, now they fill up the whole screen. I can not open two folders at a time now. I wanted to burn information for my son today, but could not get the document folder and burn folder on same screen to drag the information onto Drive E folder to burn. I can not figure out how to fix problem. I have windows 10.

Not exactly sure what you are doing here, but you can "snap" a window to fill exactly half of the screen. Just grab it at the top and drag it over to the side of the desktop. When the cursor touches the edge, it will snap to half size.

Of course, you can always resize as you like with the maximize/minimize icon next to the "x" in the upper right.

Draclvr, I can not recall ever having that happen to me before. Thank you. Your suggestion fixed the problem. I do not have a clue how it got messed up. Probably something I touched and should not have. Thank you again.

Great! Believe me, I've wondered what the heck I did to change things myself now and then...
