I just batch edited some pictures with Preview and changed the name of one file in the Preview window.
Minutes later, Finder still didn't show the changed file sizes (not even when opening the Info dialog) and changed names. Switching from list view to icon view or so didn't fix it.
I restarted Finder and then the names changed.
How come, is there an update or refresh command? Thought it'd be in the View menu but it isn't.
