The Filename and ParentDirectory commands return the filename and the parent directory, respectively, of the file referenced by the filepath path.

The filepath path must be syntactically correct, but is not required to correspond to an existing file or directory.

The behavior of this command may dependent on the platform on which it is executed and the character used to delimit directories on the current platform.
