I am trying to run robocoy with the secfix option but I am getting this error.
Does anybody know why?

Thank you,


C:\>robocopy P:\testViceversa\ Q:\TestViceversa\  /secfix /xo /xn /xc

   ROBOCOPY     ::     Robust File Copy for Windows     ::     Version XP010

ERROR : Invalid Parameter #3 : "/secfix"

       Simple Usage :: ROBOCOPY source destination /MIR

             source :: Source Directory (drive:\path or \\server\share\path).
        destination :: Destination Dir  (drive:\path or \\server\share\path).
               /MIR :: Mirror a complete directory tree.

    For more usage information run ROBOCOPY /? or read Robocopy.Doc.

NOTE: Read "True Replication" in Robocopy.Doc prior to first use of /MIR !
****  /MIR can DELETE files as well as copy them !

    This article
    explains that the /secfix flag has been deprecated. (Deprecated means replaced by a newer concept, but is still retained for backwards compatibilty until users have had a chance to phase out its use. Although the article says /secfix is deprecated in version 10 of robocopy, from your error message it looks more like it has actually been removed entirely :))

    The article above suggests using the format

    ROBOCOPY source destination /IS /COPY:SOU

    The information here

    indicates that the /COPY:SOU will copy the Security, Owner and aUditing, and /IS means to overwrite files even if they are already the same.
