Adding a conditional case in _guess_files to confirm that the complete path is put together in even if a portion of the path is a location that exists.

For instance if C:/Program Files (x86)/folder is passed to _guess_files, it would resolve to ['C:/Program Files', '(x86)/folder'] since C:/Program Files is an actual file location that can exist.
