So I've been downloading a lot of primary apps I'll be using for my new Mac for the past couple of days. However, I'm getting really confused what to do with the .dmg files. They're all over the place: on my desktop, in my downloads folder, in Finder, in my trash bin. Let's say I download an application. The .dmg file shows up in my downloads folder. What do you guys ordinarily do from there? I'm not supposed to delete the .dmg file once it's downloaded, right? Where do you guys store it? Also, when an icon appears on your desktop and you don't want it there, what do you do? Delete it? Or relocate it? And if so, where? I'd appreciate if anyone could help me understand this.
