If I have several app icons that I make a folder for....and drag those icons into that folder....when I go back to drag the "old icons" into the trash....I get a question of "do I want to uninstall the app"...I cancel, as I don't. But, I am trying to free up space on my screens. I must be forgetting something. Otherwise, I am simply losing space, by taking up space with a folder and not being able to delete the icons. What am I not doing right?
