This exception is raised on Windows, for compatibility with previous releases of FilePath where unportable programs may have done "except WindowsError:" around a call to children().

It is private because all application code may portably catch UnlistableError instead.

Inherited from UnlistableError:

Instance Variable originalException the actual original exception instance, either an OSError or a WindowsError.
Method __init__ Create an UnlistableError exception.
