Check out the cool animations folders have when you drag a file over them... they open up. Then if they're filled, the folder shows papers in them, otherwise they don't. They also have an animation for when the file does actually move into it.
This was in Mac OS X even in the Tiger days but nice they bring back some charm. I also like these folders more than the one we previously had with Big Sur to Sequoia. They look far less childish.
