Sorry for such a newbie question, but I haven't seen this addressed elsewhere. I've noticed that when I download an application or utility to try out, in the .dmg image it just says "drag to your Application folder" (or words to that effect) to install. But when I drag the application over, the copy progress bar pops up to show the copy...but then I also see these little things also being copied somewhere else too but it goes so fast I can't catch what they are and where they're going. What is this exactly? Is it just the OS making reference files as to what the file I'm dragging over is and where it is? For like Spotlight? If I want to uninstall the file, it's still just the easy function of just dragging the app to the trash, right? (well, I use Spotlight to search for items related to the app too) Just curious.
