ASP如何检测某文件夹是否存在,不存在则自动创建

直接给大家分享一下服务器之家测试正常可以使用的代码，并且支持多级目录创建

代码一

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/")

代码二、测试ok

'自动创建多极目录
'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

测试代码

createit("/202004/tools/")

以上代码如果无法运行，请检查iis运行用户的权限是否有写功能。今天测试的时候默认iis7.5下是无法运行的。

下面的实现代码功能性简单，适合学习

ASP如何检测某文件夹是否存在,不存在则自动创建

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

都不完善，我想楼主的意思是创建无极深度目录吧，给个我写的： 

'创建新文件夹(允许无级创建)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

创建文件夹

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

删除文件夹

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

复制文件

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("../无标题2.bmp"),"D:\网站项目\photo\aspupload\07_images\")

下面是其他网友的补充

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

 检查文件夹是否存在，不存在则创建文件夹，该函数无返回值。

例：CheckAndCreateFolder("ASP")

检查当前目录下是否存在ASP文件夹，不存在则创建文件夹ASP ，缺点是不支持多级目录创建。

 asp关于fso函数，文件与文件夹的相关操作用得到
