先來看看網上別人提供的程式碼：

'判斷資料夾是否存在
Function FolderExits(Folder)
Folder=Server.Mappath(Folder)
Set FSO= Server.CreateObject("Scripting.FileSystemObject")
IF FSO.FolderExists(Folder) Then
   FolderExits=true
Else
   FolderExits=false
End IF
End Function
'判斷檔案是否存在
Function FileExits(FileName)
FileName=Server.Mappath(FileName)
 
Set FSO= Server.CreateObject("Scripting.FileSystemObject")
IF FSO.FileExists(FileName) Then
   FileExits=true
Else
   FileExits=false
End IF
End Function

'建立資料夾
Function CreateFolder(Folder)
on error resume next
Folder=Server.Mappath(Folder)
Set FSO = Server.CreateObject("Scripting.FileSystemObject
 
")
FSO.CreateFolder(Folder)
if err>0 then
  err.clear
  CreateFolder=False
else
  CreateFolder=True
end if
End function

'建立檔案
Function CreateFile(FileName,Content)
on error resume next
FileName=Server.Mappath(FileName)
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
set fd=FSO.createtextfile(FileName,true
 
)
fd.writeline Content
if err>0 then
  err.clear
  CreateFile=False
else
  CreateFile=True
end if
End function

'刪除檔案
function DeleteFile(FileName)
on error resume next
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
if FSO.FileExists(FileName) then
  FSO.DeleteFile FileName,true
end if
if err>0 then
  err.clear
  DeleteFile=False
else
  DeleteFile=True
end if
end function

'刪除資料夾
function DeleteFolder(Folder)
on error resume next
Folder=server.MapPath(Folder)
Set FSO = Server.CreateObject("Scripting.FileSystemObject")
if FSO.FolderExists(Folder) then
  FSO.Deletefolder Folder,true
end if
if err>0 then
  err.clear
  Deletefolder=False
else
  Deletefolder=True
end if

我們自己也寫一個簡單的判斷

'從引數獲取檔案或資料夾路徑
Set objArgs = WScript.Arguments
msgbox objArgs.count
For x = 0 to objArgs.Count - 1
    msgbox objArgs(x)
Next

s=objArgs(0)
set fso=createobject("scripting.filesystemobject")
msgbox s
If fso.FileExists(s) Then
    msgbox("是檔案")
ElseIf fso.FolderExists(s) Then
    msgbox("是路徑")
Else
    msgbox("什麼都不是")
End If
