直接給大家分享一下測試正常可以使用的代碼，并且支持多級目錄創建

代碼一

 Function CreateMultiFolder(ByVal CFolder) 
Dim objFSO, PhCreateFolder, CreateFolderArray, CreateFolder 
Dim i, ii, CreateFolderSub, PhCreateFolderSub, BlInfo 
BlInfo = False 
CreateFolder = CFolder 
On Error Resume Next 
Set objFSO = Server.CreateObject("Scripting.FileSystemObject") 
If Err Then 
    Err.Clear() 
    Exit Function 
End If 
If Right(CreateFolder, 1) = "/" Then 
    CreateFolder = Left(CreateFolder, Len(CreateFolder) -1) 
End If 
CreateFolderArray = Split(CreateFolder, "/") 
For i = 0 To UBound(CreateFolderArray) 
    CreateFolderSub = "" 
    For ii = 0 To i 
CreateFolderSub = CreateFolderSub & CreateFolderArray(ii) & "/" 
    Next 
    PhCreateFolderSub = Server.MapPath(CreateFolderSub) 
    If Not objFSO.FolderExists(PhCreateFolderSub) Then 
objFSO.CreateFolder(PhCreateFolderSub) 
    End If 
Next 
If Err Then 
    Err.Clear() 
Else 
    BlInfo = True 
End If 
CreateMultiFolder = BlInfo 
End Function

使用方法：

CreateMultiFolder("/202003/tools/")

代碼二、測試ok

"自動創建多極目錄
"code by jb51 reterry
function createit(path)
dim fsofo,cinfo,thepath,thepatharray
dim i,ii,binfo
binfo=false
thepath=path
set fsofo=createobject("scripting.filesystemobject")
if err then
err.clear
exit function
end if
thepath=replace(thepath,"\","/")
if left(thepath,1)="/" then
thepath=right(thepath,len(thepath)-1)
end if
if right(thepath,1)="/" then
thepath=left(thepath,len(thepath)-1)
end if
thepatharray=split(thepath,"/")
for i=0 to ubound(thepatharray)
createfoldersub1=createfoldersub1&thepatharray(i)&"/"
createfoldersub=server.mappath(createfoldersub1)
if not fsofo.folderexists(createfoldersub) then
fsofo.createfolder(createfoldersub)
end if
next
if err then
err.clear
else
binfo=true
end if
createit=binfo
end function

測試代碼

createit("/202004/tools/")

以上代碼如果無法運行，請檢查iis運行用戶的權限是否有寫功能。今天測試的時候默認iis7.5下是無法運行的。

下面的實現代碼功能性簡單，適合學習

ASP如何檢測某文件夾是否存在,不存在則自動創建

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

都不完善，我想樓主的意思是創建無極深度目錄吧，給個我寫的： 

"創建新文件夾(允許無級創建)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 

創建文件夾

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

刪除文件夾

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

復制文件

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("../無標題2.bmp"),"D:\網站項目\photo\aspupload\07_images\")

下面是其他網友的補充 

Public Function CheckAndCreateFolder(FolderName)
　　fldr = Server.Mappath(FolderName)
　　Set fso = CreateObject("Scripting.FileSystemObject")
　　If Not fso.FolderExists(fldr) Then
 　　fso.CreateFolder(fldr)
　　End If
　　Set fso = Nothing
End Function

 檢查文件夾是否存在，不存在則創建文件夾，該函數無返回值。

例：CheckAndCreateFolder("ASP")

檢查當前目錄下是否存在ASP文件夾，不存在則創建文件夾ASP ，缺點是不支持多級目錄創建。

 asp關于fso函數，文件與文件夾的相關操作用得到
