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
