Windows 10 is packed with convenient keyboard shortcuts. One especially handy shortcut lets you open File Explorer in an instant from any application. This trick dates back to Windows 95, and it still works on Windows 10 today.
If you'd like to open File Explorer with a keyboard shortcut, press Windows+E, and an Explorer window will pop up.
From there you can manage your files as usual.
To open up another Explorer window, press Windows+E again, or press Ctrl+N if Explorer is already open. To close an Explorer window with a keyboard shortcut, press Ctrl+W.
