"Add Files" screen to large

[RobertCBoston]

I frequently combine .pdf files, and use the "add file" feature in my Adobe Standard 2021.  Somehow I hit a button on my keyboard, and the 'add files' screen is now full-size, taking up the entire screen.  Does anyone know how to reduce the screen to a smaller size?  I can't "drag" the corner in to reduce the size, so I am stuck.  Thanks.

Hi Robert,

Hope you are doing good.

From the above description, if we understand correctly, then you are referring to this window here:

Double-click on the blank space right at the top of the folder path. The window will be shrinked. You can also drag the window from here and drop it to the desired location 

Thanks,
