Do you have a folder or file you need to access all of the time? Well, you can keep a shortcut to it on your Finder toolbar at all times. First, find the folder or file in the Finder. Next, click and hold the file, and drag it to the area of the toolbar you want.
If you want to remove it from your toolbar, just right-click on the icon, and click Remove Item.
