建立目录的程序，如果有多级目录，则一级一级的创建
程序代码：
'建立目录的程序，如果有多级目录，则一级一级的创建
function createdir(byval localpath)
on error resume next
localpath = replace(localpath,"\","/")
set fileobject = server.createobject("scripting.filesystemobject")
patharr = split(localpath,"/")
path_level = ubound(patharr)
for i = 0 to path_level
if i=0 then pathtmp=patharr(0) & "/" else pathtmp = pathtmp & patharr(i) & "/"
cpath = left(pathtmp,len(pathtmp)-1)
if not fileobject.folderexists(cpath) then fileobject.createfolder cpath

createdir = false
err.clear
else
createdir = true
end if
end function
下面列举一下这些不常用但是却非常酷的功能：
很少被了解的fso功能
getspecialfolder method 返回特定的windows文件夹的路径: windows安装目录；windows系统目录；windows临时目录 fso.getspecialfolder([0, 1, or 2])
gettempname method 返回一个随机产生的文件或者目录名字，用于需要存储临时数据时
getabsolutepathname method 返回文件夹的绝对路径(类似于server.mappath)。
比如，fso.getabsolutepathname("region") 将返回类似于下面的结果："c:mydocsmyfolder egion"
getextensionname method 返回路径中最后部分的扩展名
(比如：fso.getextensionname("c:docs est.txt") 将返回txt)
getbasename and getparentfolder methods 返回路径中最后部分的父文件夹
(比如：fso.getparentfolder ("c:docsmydocs") 将返回'docs')
drives property 返回所有本地可用驱动器的集合，用于建立资源浏览器样的用户接口。
使用上面的功能时，最好建立好出错处理的代码。因为如果需要的参数不存在，将会产生麻烦的信息。
