From a usability perspective, many folks (me included) will open a folder and scroll up/down (browse) to find a file that we may not be sure of the exact filename.
Norton restore needs to offer the same capability. Currently you have try searching a variety of guesses as to the file name, either in Office Documents, or Picture, etc, but you can't do that you select a particular folder where you know where it is.
Why not just show a directory listing capability just like you get with Explorer? All the other options can still be there for those who like that.
