What I was talking about wasn't media player. Just for reference, in Windows File Explorer window, if you have Preview enabled and the navigation pane on the left(the tree view with desktop computer documents etc.) all you have to do is select media files with the mouse and it gives the total file space and play time in that blue area at the bottom(at least it's blue on my system but I'm running Vista "purple" theme, so who knows? )
It is a handy feature. Just saves dragging the files to some media app to get that info.
