When I highlight several folders in Finder and do a get info, I get an info window for each folder. Is there a way to get a single window showing size of all folders highlighted?


Open a finder window and set the view to list view. Press command-J and select "calculate all sizes" then click "use as standard".

Now folder sizes will show in your finder. I don't think it is possible to show sizes for multiple folders, but this might be a good workaround.

    cmd+alt+i and highlight what you need – iskra Dec 9 '11 at 15:55

cmd+alt/option+i will give you info on multiple highlighed items.

  • How is alt done since it is own the option key? – 4thSpace Dec 9 '11 at 16:06

There are 3 forms of "Get Info":

1) Standard "Get Info" achieved through Command+i which can potentially create multiple windows for each item selected.

2) "Get Summary Info" achieved through Command+Control+i which uses a single window to show combined info about the selection:

3) "Inspector", like @iskra mentioned, achieved through Command+Option+i, which is similar to 2) except that it updates the info dynamically based on your selection.

  • open Terminal.app
  • cd to the directory 'above' the ones you need the size for
  • du -sh FOLDER1 FOLDER2 gives sizes in "human readable" format (Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte.)
  • du -sm FOLDER1 FOLDER2 gives sizes in megabytes
  • du -sg FOLDER1 FOLDER2 gives sizes in Gigabytes
  • 1
    Or go into terminal, type du -sm and drag all the files you want to include in the calculation in there – vrwim Jan 31 '16 at 23:07
