How can I find the size of multiple folders?
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/option+i will give you info on multiple highlighed items.
