File size in finder ' get info' does not refresh
I'm moving files about and need to check how large the folders are (in preparation for burning a dvd). 'Get info' is not refreshing the file size (and it's not just enormous folders). I have installed 'Refresh Finder' but it doesn't make any difference. The only way I can see the true file size is by restarting (a pain). What else can I try?
