When using Extended File Specifications, directory names conform
    to most of the same conventions as file names when using the
    ISO Latin-1 character set. Periods and special characters may
    be present in the directory name, but they must be preceded by a
    circumflex (^) in order to be recognized as literal characters,
    as shown in the following table:

    CREATE/DIRECTORY. . .       Result
