By default, when you open a new Finder window, Finder brings you to your Home Folder. This folder contains folders for Applications, Documents, Music, Photos, Movies, Library, Sites, etc.
This can be useful if you need to browse different folders to find a file. However, if you frequently go to the same folder over and over again—say, your Documents folder or Pictures folder, the default view requires you to click over to that folder. It would be nice to open a new Finder window and be brought directly to your most-frequented folder.
To do this, all you need to do is open a Finder window by clicking on the blue Finder icon in the left corner of your Dock, or by clicking on the hard drive icon on your desktop. If you’re already in the Finder, you can also use the keyboard shortcut Command-N to open a new window. Next, under the Finder menu, click Preferences. You’ll now see drop down menu labeled “New Finder windows open:“. From the drop down menu, you can choose the folder or location of your choice.
