The string returned by the ToString method represents path that was passed to the constructor. When you create a FileInfo object using the constructors, the ToString method returns the fully qualified path. However, there are cases where the string returned by the ToString method does not represent the fully qualified path. For example, when you create a FileInfo object using the GetFiles method, the ToString method does not represent the fully qualified path.
