VBS 同步文件夹 [翻译+转载 by yu2n]
功能：  同步文件夹，只更新已修改(或新增)的文件及文件夹，支持删除多余(目标文件夹中存在，源文件夹不存在)的文件及文件夹
参数：  sync.vbs  [/RD]  [/RF]  [/C]  <sourcePath>  <destinationPath>
  sourcePath  源文件夹
  destinationPath  目标文件夹
  /RD 删除目标文件夹中多余的文件夹；
  /RF 删除目标文件夹中多余的文件；
  /C  等于同时使用 /RD /RF 参数
源代码下载：  http://www.robotii.co.uk/wp-content/uploads/2008/10/sync.vbs
个人说明：  此脚本是我使用过的同步脚本中效率及兼容性最高的。

' sync.vbs
'
' This script makes a "synchronised" backup of a folder tree from one
' path to another.
'
' Extraneous directories (folders) may be removed from the destination
' tree by specifying the /RD switch on the command line.  These are
' directories already existing in the destination tree but no longer
' found in the source tree.
'
' Extraneous files may be removed from the destination tree by specifying
' the /RF switch on the command line.  These are files which exist in
' destination directories but not in source directories.
'
' Both extraneous directories and files can be removed by specifying the
' /C switch on the command line. This switch is equivalent to specifying
' both the /RD and /RF switches
'
' Usage:  sync.vbs <sourcePath> <destinationPath>
'    or:  cscript /nologo sync.vbs <sourcePath> <destinationPath>
'    or:  wscript /nologo sync.vbs <sourcePath> <destinationPath>
'
' Notes:  Paths can use drive letters or UNC specifications.
