Silly question, I know. If I were an icon expert, I would just make one. But I'm not. And that 'old' folder icon just looks 'funny' with the new 'flat' icons! Anyone up to the challenge? Clinton
I agree, looks a bit weird having that old icon amongst the new icons. Somebody has already made an icon: http://sc20k1.deviantart.com/art/Windows-Folder-Icon-for-OS-X-Yosemite-463209561
