ASP怎样检測某目录是否存在,不存在则自己主动创建

folder=server.mappath("/imagess") 
Set fso = CreateObject("Scripting.FileSystemObject") 
if fso.fileexists(Server.mappath(filepath)) then 
respnse.write("都有了还建什么建") 
else 
fso.createfolder(folder) 
end if 
Set fso = nothing

Dim objFSO 
Set objFSO = Server.CreateObject("Scripting.FileSystemObject") 
If objFSO.FolderExists(Server.MapPath(SavePath))=false Then 
objFSO.CreateFolder(Server.MapPath(SavePath)) 
End If

folder=server.mappath("/imagess") 
Set fso = CreateObject("Scripting.FileSystemObject") 
if fso.fileexists(Server.mappath(filepath)) then 
respnse.write("都有了还建什么建") 
else 
fso.createfolder(folder) 
end if 
Set fso = nothing   

都不完好，我想楼主的意思是创建无极深度文件夹吧，给个我写的： 

‘创建新目录(同意无级创建)1:35 2005-1-31 
Public Function CreateFolder(FolderPath) 
Dim sObjFSO 
Dim arrFolder 
Dim i 

Set sObjFSO = Server.CreateObject("Scripting.FileSystemObject") 
FolderPath = Replace(FolderPath,"\","/") 
arrFolder = Split(FolderPath,"/") 
On Error Resume Next 

For i = 0 To UBound(arrFolder) 
If i > 0 Then arrFolder(i) = arrFolder(i-1) & "/" & arrFolder(i) 
If Not sObjFSO.FolderExists(arrFolder(i)) Then 
sObjFSO.CreateFolder(arrFolder(i)) 
End If 
Next 
CreateFolder = True 

If Err.number <> 0 Then 
CreateFolder = False 
Err.Clear 
End If 
End Function   

创建目录

dim fso,SavePath
SavePath=server.MapPath(".\"&imagefile&"\"&username&"\"&specialname&"")
set fso = server.CreateObject("scripting.filesystemobject") 
if fso.FolderExists(SavePath)=false then 
fso.createfolder(SavePath) 
end if
set fso=nothing

删除目录

dim fso,SavePath
SavePath=server.MapPath(".\"&imagefile&"\"&username&"\"&specialname&"")
set fso = server.CreateObject("scripting.filesystemobject") 
if fso.FolderExists(SavePath)=true then 
fso.deletefolder(SavePath) 
end if
set fso=nothing

拷贝文件

dim fso
set fso=server.CreateObject("scripting.filesystemobject")

sub copyfiles(path,path2)
   set mycopy=fso.getfile(path)
   response.flush()
   mycopy.copy path2
   response.write("<b>installed success !&nbsp;&nbsp;</b>"&path2&"<br>")
   response.Flush()
   end sub
call copyfiles(Server.MapPath("../无标题2.bmp"),"D:\站点项目\photo\aspupload\07_images\")
