Finder is just like Explorer in Windows. There are several ways to open Finder. Switchers, as well as Mac users, will find this article useful.
Finder at Dock
The most common way to open new Finder window is by clicking on the Finder dock icon and this is also the way I use at the very first time using my Mac.
Finder from Menu Bar
This is quite rare for Mac users to open Finder from menu bar. However, there is a very useful keyboard shortcut that we can extract out here from the menu bar to open new Finder window, i.e. Command-N.
Finder and Quicksilver
Sometimes, you will want to have different experience on using your Mac, you can try open your Finder with Quicksilver. Invoke Quicksilver, search for Finder by typing
find, and open it. It’s easy right?
Finder with Advanced Dock Click
Most of Mac users have already know this : when you pressed your Command modifier key and click on one of your dock icons, you will be redirected to your new Finder window where the application inhabits.
I was a switcher not long time ago and I made a fundamental mistake : in Mac, Return key means you want to rename the file/folder, to open the particular file/folder you should use Command-O.
