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.
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.
Get Summary Info" achieved through Command+Control+i which uses a single window to show combined info about the selection:
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
cdto the directory 'above' the ones you need the size for
du -sm FOLDER1 FOLDER2gives sizes in megabytes
du -sg FOLDER1 FOLDER2gives sizes in Gigabytes
