Set a default folder to appear each time you open a new Finder window

If you navigate to a particular folder often, then you can set it as your default and save yourself a few clicks each time you open the Finder. Click the Finder menu in the menu bar and then select Preferences. Under the General tab, you will see that for New Finder windows show, the default is All My Files. You can change to your Home or Documents folder, or whichever folder you use the most.

Automatically remove items from the Trash

If you click the Advanced tab in Preferences, you’ll see a number of boxes to check, including Remove items from the Trash after 30 days. This can help you keep your trash from overflowing with files.

Open a new Finder window

Need to open another Finder window. You can use a keyboard shortcut for that. Hit Command + N to open a new Finder window. You can also use Command + T to open a new Finder tab, which allows you to view various folders within a single Finder window.

Open a specific folder in the Finder

Instead of looking for a folder, you can use the following keyboard shortcuts to open a specific folder:

• Command + Shift + C: Top-level Computer folder
• Command + Shift + D: Desktop folder
• Command + Shift + F: Recents folder
• Command + Shift + G: Go to Folder window
• Command + Shift + H: Home folder for your account
• Command + Shift + I: iCloud Drive folder
• Command + Shift + O: Documents folder
• Command + Shift + R: AirDrop folder
• Command + Shift + U: Utilities folder
• Command + Option + L: Downloads folder

Quickly search for a file or folder in the Finder

Although you can click on the magnifying glass in the top-right corner of any Finder window to search for a file folder, you can also use the keyboard shortcut Command + F to open Finder with the search bar already activated.

Get info about a file or folder in the Finder

Need more information about a file or folder, such as file kind, folder size, date created or last modified? You can hit Command + I to open the Get Info panel for any selected file.

Show or hide the Sidebar in the Finder

If you need a cleaner view, use Command + Option + S to show or hide the Finder’s sidebar. Hit Command-Control-T to add a selected item — a folder, usually — to the sidebar.

Show or hide the path bar in the Finder

Finder has another information bar in addition to the sidebar: the path bar. It’s the narrow bar along the bottom edge of Finder that shows you the folder path to the file you currently have selected. If you want to hide or show it, hit Command + Option + P.

Change the Finder view

You can change the view of the Finder by clicking the four buttons in the menu bar at the top of a Finder window. Alternatively, you can use keyboard shortcuts:

• Command + 1: Icon view
• Command + 2: List view
• Command + 3: Column view
• Command + 4: Gallery view

Check out your view options

Hit Command + J to open the View Options panel. This lets you choose, among other things, the types of columns — Date Modified, Size, Tags and so on — that you want to see for Finder’s column view. You can set different columns to show for different folders in Finder.

Quickly view a file without opening it

You can always double-click a file to view it, obviously, but there is a way to simply preview it. If you click on a file once, to highlight it, and then hit the spacebar, you can check out a preview of it. If you hold down Option + spacebar, you can open a full-screen slide of the file.

Create a new folder

Just like on your desktop, you can use the Command + Shift + N keyboard shortcut to create a new folder in the Finder.

Quickly trash a file or folder

Save yourself the trouble of dragging a file to the trash can in your dock. Instead, select the files or folders in the Finder you’d like to trash and hit Command + Delete. In related news, you can hit Command + Shift + Delete to empty the trash.

Add a file or folder to your dock

Use Command + Control + Shift + T to add a file or folder in Finder to the dock. It will sit to the right of the dock’s divider.

Customize the Finder toolbar

From the menu bar at the top of the screen, go to View > Customize Toolbar to drag buttons to and from the toolbar at the top of the Finder. If you find that you don’t like the changes you made, just drag the default set back to the Finder to start again.
