Can't duplicate directory with keybindings

Problem: Duplicate file action only works on open files, not directories.
Solution: The extension should be able to duplicate without an active text editor.

Steps to reproduce:

If I have selection on a folder

I can't duplicate it with this keybinding.

    {
        "key": "ctrl+d",
        "command": "duplicate.execute",
        "when": "explorerViewletVisible && filesExplorerFocus && !explorerResourceIsRoot && !inputFocus"
    },

It gives the error:

No active text editor
