The Finder is the main ally that we have in macOS to be able to access all the information that we have stored on our computer's hard drive. It is the equivalent of the Windows file explorer but, as you can guess, with certain differences in terms of how it works on the Mac.
When we click on the icon Finder in the Dock, which normally and if you have not changed its place is the first icon that we find in the bottom bar of the desktop, a Finder window opens. In the first versions of the Mac operating system, when we pressed the Finder icon, we were shown one and only one window and that is we couldn't have more than one Finder window open on the screen at the same time.
With the passing of the macOS versions that has changed and now it is possible to open as many Finder windows as you want. Now, if you look at the following screenshot, a Finder window is made up of a left sidebar that shows the different locations where the files of our system can be located, an area on the right where we are shown the content in each of the items in the left sidebar and a top bar in which there are a series of buttons with which configure views, Back / Forward, Organize, Share, Tags, etc.
So far, I don't think I have taught you anything that you didn't already know, but the fact is that the Finder window can be vitaminized with two keyboard shortcuts, making the path of any file that we select or that appears in the lower part of the window at the top show us a bar of tabs to being able to have multiple Finder windows in the same place and not as separate windows.
Add file path at the bottom of the Finder window
In order to make the bar appear at the bottom of the Finder window where the path of the file we select is shown, we open a Finder window and then press the key combination ⌥⌘P. Now when you select a file you will see how the path of the same appears in that bar on the system's hard disk.
Add tab bar to the top of the Finder window
However, in case you want the tab bar to be displayed at the top of the Finder windows, the key combination you must press on your Mac keyboard will be ⇧⌘T.
