Do you wish you could see a different folder to “All My Files” when you open a new Finder window in macOS?
If like myself you prefer to have your Documents (or any other folder) show it is extremely easy to change the default behavior to one that suits your individual requirements.
In the Finder menu (usually showing when you click on your Desktop) select Preferences or you can just hit the key combination Command ⌘ + , which will show the Finder Preferences.
Click on the selection box below “New Finder windows show” and select the folder you would like to display (if your folder is not there click on other and navigate to your desired location) (img.1).
Each new Finder window will now open showing your selected folder.
