The Finder is the app that helps you navigate all of the files and folders on your Mac. The Finder lets you browse your apps, disks, files, and folders in a variety of ways. You can use the Finder to organize these items the way you want. You can also use the Finder to search for items, delete files you no longer want, and more.
To open a new Finder window, click the Finder icon in the Dock, then select File > New Window.
You can change how items are displayed in Finder windows by dragging them, arranging them, or changing their view. Use the View menu to change the view of the current Finder window. You can also click the corresponding View button in the Toolbar that appears at the top of Finder windows.
List View
Choose View > as List to see the items in a consecutive order. You can change the sort order of the list by clicking the headers (Name, Documents, Kind, Date) at the top of the list view. Click the same header a second time to switch between ascending and descending order.

If an item is within a folder, you can click the triangle next to the folder name to see any items stored within that folder.
Arranging items
You can arrange items in a folder from the View menu as well.
For example, if you are viewing your files as icons, you might want to sort the icons alphabetically. Choose View > Arrange by name to tell the Finder to re-sort the items in alphabetical order. The Finder keeps the window organized this way until you select another option from the View menu, or until you select None.
