Judgment Whether a file is considered hidden or not, the exact definition of hidden depends on the platform or provided program. For example, on UNIX, a file is considered hidden if its name begins with a period character ("."). On Windows, a file is considered hidden if it is not a directory and the DOS hidden attribute is set.
