The addition of the Control key is important, as it’s the only way to access the “Summary” view we’re looking for. Alternatively, you can access the same window by selecting your items, holding the Control key on the keyboard, and heading to File > Get Summary Info in the menu bar. Note the addition of the Control key to our normal “Get Info” shortcut. Here, you can see the total number of selected items as well as their combined file size. Once all of your files or folders are selected, use the keyboard shortcut Control-Command-I to access the Multiple Item Info window. Alternatively, holding Shift and clicking on items (or using the arrow keys to navigate the list of files) will select the first item plus all adjacent or sequential items after it. Holding Command and clicking on non-adjacent items will select each one without de-selecting prior items.

To select multiple files or folders in macOS, you can either click and drag over both items at once using the mouse or trackpad (which is good for just a few items like we have here), or you can use the Command or Shift keys in combination with your mouse or arrow keys. So, instead, we can select both files together and then use a special form of the Get Info command to view the combined total size. But that’s tedious with just two folders, not to mention a scenario in which I want to see the combined size of hundreds or even thousands of folders and files. Now, I could select each folder individually, open the Info window, note the total file size, repeat for the second folder, and then add the two sizes together. I want to know just how much storage space these two folders are currently occupying. For our example, let’s say that I have two folders on my desktop (highlighted by the red box in the screenshot below): Let’s illustrate how this process to use the Info window on multiple files or folders works.
