Show Folder Sizes in Mac OS X List View

Apr 5, 2011 - 11 Comments


This should probably be enabled by default, but the standard Mac OS X list view setting is to not display the size of folders and their contents. No big deal, this is easily changed:

  • First, make sure to select list view from a Finder window
  • Now open “View Options” from the View menu (or hit Command+J)
  • Select the checkbox next to “Calculate all sizes”

Now when you open any directory in list view, you’ll see the size of directories and their respective contents. This also works with Cover Flow view, but must be set separately through View Options.

  1. While I agree this is very convenient, I disagree that it should be enabled by default – calculating folder sizes is expensive and requires many disk access operations.

    i have to do it for every folder seperately… how can i do it for all folders?

    • Paul says:

      If you want to have this automatic for all folders click on the “Use as Defaults” button in View Options, it will apply to all directories that are open in list or coverflow view.

      As Olivier notes though it will cause your disk to be more active.

    I agree with Olivier. this could be very resource expensive. I rather consult for each folder.
