Automatically show folder size in details mode

I want DO to show the folder size automatically instead of hovering my mouse over all folders in details mode. How can I do that, please help me, thanks.

See this FAQ: Calculate Folder Sizes Automatically.

You also might want to be aware that having automatic folder calculation enabled can significantly slow down the loading time when you enter a folder (while Opus does the calculating of all the folders).

The sizes are calculated in he background after the folder loads, so it might slow down other things you do after loading the folder but it shouldn't slow down loading the folder itself.

Thanks for your rapid answers.
I got it. I know it takes a little little long to enable this, but no problem to me. Thanks again, everybody :wink:.
