       When source is directory, if target is not exist,
       target directory is created. If target exists,
       with /c option, a directory with same name as source directory is created
       in the target directory(required to be existing),
       without /c, all members of the source directory are copied into the destination directory.

       Copy to file from directory is denied.
       (It is the difference from native COPY cmd, COPY cmd treated like as XCOPY).
       Override to read-only file is also denied.
       Hidden file,empty sub directory is copied also.
       Copy is denied when target has system and/or hidden
       attribute and source dose not have corresponding
       attribute even if /r is specified.
       To override existing file,specify /y or /r after target filename.
       Without /+ option,File attribute like as timestamp is
       copied.
#ifdef UNX
       To skip copy file info,specify -n option.
       Permission err may occur to copy file info even if
       copy is avail case.
#endif

       /y   replace if same name file already exist.
            stop copy with no /y if same name file already exist.
       /y-  skip copy when same name file exist and continue process.
       /r   same as /y
       /r-  same as /y-
       /b   TSO file transfer without conversion.
       /c   if copy source is dir or wildcard,create source dir in
            target dir if same name dir is not exist in target dir.
            If source is dir and target is wildcard, renamed target is created if nor exist,
            and members of source is copied to renamed target(RenameCopy).
       /d   (effective other than OS/2)select only files source is new.
            Note) for remote upload,file timestamp is not preserved
                  and current time is set.
       /+   append  if same name file already exist.
       /:   it is needed if you copy between root directory.
       /s   copy sub directory
       /s-  do not copy sub directory(default)
