Hi. I'm new to Mac. I've been using a fully upgraded MacBook Pro for about a week now and so far, I love it. A couple of questions: 1. What is the difference between a Finder and Spotlight? 2. My Applications folder is really cluttered with far too many files. I'd like to organize the directory by putting them in newly created sub-folders (Microsoft Word, RevTex, and Pages in Word Processing folder, for instance). Would this kind of relocation create complications later on such as interfering with automatic software updates, ...etc.? If yes, how would I go about reorganizing my Applications directory without problems?
