I'm not an experience Illustrator user, but whenever I use pathfinder to combine a few layers together, Illustrator would create a whole bunch of what appears to look like outlines of every shape and thin thin hairlines that doesn't show up on my art board when I turn on the visibility. I can only see them when I look at the layers on the side. It doesn't seem to make a difference to my art when I delete all of those layers. Can someone tell me what these layers are and if it is alright to just delete them?
