| /// Since FileSystemEntity is abstract, every FileSystemEntity object is |

| /// Calling exists on an instance of one of these subclasses checks whether the |
| /// object exists in the file system object exists and is of the correct type |
| /// (file, directory, or link). To check whether a path points to an object on |
| /// the file system, regardless of the object's type, use the type static |

| /// @note The test should run with the Administrator priveleges on Windows. |
| /// Dart API Spec reads: |
| /// In order to create a symbolic link on Windows, Dart must be run in |
| /// Administrator mode or the system must have Developer Mode enabled, otherwise |
| /// a FileSystemException will be raised with ERROR_PRIVILEGE_NOT_HELD set as |
| /// the errno when this call is made. |
