Windows: Creating a new folder in Windows is easy, but not necessarily fast. Smart Folders is a simple little app that turns folder creation into a simple, one-step process.
Smart Folders makes folder creation easy by making it a drag-and-drop operation, rather like iOS or Android 4.0: just drag one file onto another (or multiple files onto another), and Windows Explorer will dump them all in a new folder instantly and ask you to rename it. It's simple, but once you try it, you'll realise how much it beats hitting Ctrl+Shift+N and moving everything yourself. If you want, you can even restrict it to certain file extensions, though by default it should work with any file. Check out the video above to see it in action.
Smart Folders is a free download for Windows only.
