我們來介紹一下asp中FSO文件操作函數，他可以實現復制文件、重命名文件、刪除文件、替換文件。

FSO文件（File）對象屬性
DateCreated 返回該文件夾的創建日期和時間
DateLastAccessed 返回最后一次訪問該文件的日期和時間
DateLastModified 返回最后一次修改該文件的日期和時間
Drive 返回該文件所在的驅動器的Drive對象
Name 設定或返回文件的名字
ParentFolder 返回該文件的父文件夾的Folder對象
Path 返回文件的絕對路徑，可使用長文件名
ShortName 返回DOS風格的8.3形式的文件名
ShortPath 返回DOS風格的8.3形式的文件絕對路徑
Size 返回該文件的大?。ㄗ止潱?br /> Type 如果可能，返回一個文件類型的說明字符串
FSO文件（File）對象方法
FSO文件對象方法 用途
CopyFile 拷貝一個或者多個文件到新路徑
CreateTextFile 創建文件并且返回一個TextStream對象
DeleteFile 刪除一個文件
OpenTextFile 打開文件并且返回TextStream對象，以便讀取或者追加

重命名文件：

代碼如下:
Function reName(sourceName,destName)
dim oFso,oFile
set oFso=server.createobject("Scripting.FileSystemObject")
set oFile=oFso.getFile(Server.mappath(sourceName))
oFile.Name=destName
Set oFso=Nothing
Set oFile=Nothing
End Function

刪除文件：

代碼如下:
Function FSOdel(fileName)
dim fso,f
set fso = server.CreateObject("scripting.filesystemobject")
f=server.MapPath(fileName)
if fso.FileExists(f) then
fso.DeleteFile f,true
end if
set f = nothing
set fso = nothing
End Function

替換文件中的字符串:

代碼如下:
Function FSOreplace(fileName,Target,repString)
Dim objFSO,objCountFile,FiletempData
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objCountFile = objFSO.OpenTextFile(Server.MapPath(fileName),1,True)
FiletempData = objCountFile.ReadAll
objCountFile.Close
FiletempData=Replace(FiletempData,Target,repString)
Set objCountFile=objFSO.CreateTextFile(Server.MapPath(fileName),True)
objCountFile.Write FiletempData
objCountFile.Close
Set objCountFile=Nothing
Set objFSO = Nothing
End Function
