I don't like the white background in File Explorer. I know about the custom theme patchers for installing custom themes but I don't want to use them for my work computer. I don't like the built-in dark themes. They are way too dark. Also I am stuck with Windows 7. I know that Windows 10 anniversary edition will have a complete nice dark theme.
So my option now is to use a File Explorer replacement. Any free ones with a dark theme? It should at least have the basic features. Copy, move, delete and rename files and folders. I don't care about ones I seldom use. I can always use the regular file explorer for those. Price maybe up to $20.
