I understand that the minimum disk allocation block is 4kb, but in Finder I don't really care about that. I'd much rather be able to see which of 12 similar text files/images is largest, expecially because I do web work and it's very useful to see the actual size of your files without having to 'get info' on all of them.

There's no simple option I can see, but if there's a terminal command or file somewhere I can edit, I'd love to be able to.

I'm using Snow Leopard 10.6.5, btw. :)

  • Odd: above 20 kB not everything is a multiple of 4 kB on my Mac, but indeed even 1 byte files show as 4 kB.

  • Using the inspector instead of Get Info (Cmd-Opt-I instead of Cmd-I) might be less painful.

Open AppleScript Editor, paste this:

tell application "Finder"
    set selection_list to selection as list

    set item_list to ""
    repeat with idx from 1 to count selection_list
        set item_list to item_list & name of item idx of selection_list & " - " & size of item idx of selection_list & " bytes
    end repeat
    display dialog item_list buttons {"OK"} default button 1
end tell

Save as application somewhere and drag it it to your Finder toolbar. Whenever you click on it, a dialog informs you of the size of the items selected in your frontmost Finder window. Screenshot

  • That is a much better alternative than Get Info! I still would love to find a way to make finder actually show the amount (I generally browse in details view).. but that might be too much to ask.

  • @Damon I think there is no alternative. I looked. Therefore the scripting solution.

Since we can't fix it, a good option would be getting an alternative to Finder. I suggest ForkLift. enter image description here
