A lot of the files in Finder are hidden. This is probably a wise choice by Apple as there are countless things you can screw up. But if you want to take a look at how many there are and what they are you can show them within Finder. Be careful as these files are needed by the system, if you screw something up don’t come complaining. Repeat the command with false to revert.
