ASP FSO操作文件(復制文件、重命名文件、刪除文件、替換字符串)
FSO的意思是FileSystemObject，即文件系統對象。FSO對象模型包含在Scripting 類型庫 (Scrrun.Dll)中，它同時包含了Drive、Folder、File、FileSystemObject和TextStream五個對象，用來操作文件和文件夾十分方便。 （請注意后面的常用函數）
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 返回該文件的大小（字節）
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 創建文件並且返回一個TextStream對象
DeleteFile 刪除一個文件
OpenTextFile 打開文件並且返回TextStream對象，以便讀取或者追加
重命名文件：
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：
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:
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
