Presentation of folder tree in File Copy and File Move dialogs

I have configured the folder tree view to have lines and + and - icons for opening and closing folders, like this:

However when I use the Copy File and Move File dialogs, the folder tree is presented in Windows' more modern style with little triangle icons to open and close folders, like this:

How can I change the folder tree presentation in the Copy and Move dialogs be the same as in the first example above, with the lines and + and - icons?

Thanks in advance.
