I have a basic question that you long time mac users can probably answer with ease. Every time I download anything such as system icons, wallpapers, etc. and then drag them to the trash my memory decreases a bit. An example is I just downloaded an icon set and decided I didn't like it so I dragged it to my trash. My memory drops from 73.81 GB to 73.72 GB. This is very annoying because I can't test out some icons and then drag them to the trash without losing memory. Can someone please help? Thanks. (^_^)
