/EXCLUDE:file1[+file2][+file3]...
              Specifies a list of files containing strings.  Each string
              should be in a separate line in the files.  When any of the
              strings match any part of the absolute path of the file to be
              copied, that file will be excluded from being copied.  For
              example, specifying a string like \obj\ or >>>.obj<<< will exclude
              all files underneath the directory obj or >>>all files with the
              .obj extension<<< respectively.
