整站二进制数据库文件还原

昨天一个在落伍的朋友给的，一个站的所有文件和图片以二进制的方式放进了数据库里，用下面的代码可以把数据库里的文件和图片还原出来。
把得到的数据库名字改成ToMdb.mdb，然后把下面的代码保存成VBS格式。放在同一个目录下，执行这个VBS文件

Dim rs, ws, fso, conn, stream, connStr, theFolder
Set rs = CreateObject("ADODB.RecordSet")
Set stream = CreateObject("ADODB.Stream")
Set conn = CreateObject("ADODB.Connection")
Set fso = CreateObject("Scripting.FileSystemObject")
connStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=ToMdb.mdb;"

conn.Open connStr
rs.Open "wz", conn, 1, 1
stream.Open
stream.Type = 1

On Error Resume Next

Do Until rs.Eof
thePath = rs("folder") & "\"
theFolder = Left(thePath, InStrRev(thePath, "\"))
If fso.FolderExists(theFolder) = False Then
createFolder(theFolder)
End If
stream.SetEos()
stream.Write rs("body")
stream.SaveToFile str & thepath & rs("file"), 2
rs.MoveNext
Loop

rs.Close
conn.Close
stream.Close
Set ws = Nothing
Set rs = Nothing
Set stream = Nothing
Set conn = Nothing

Wscript.Echo "所有文件释放完毕!"

Sub createFolder(thePath)
Dim i
i = Instr(thePath, "\")
Do While i > 0
If fso.FolderExists(Left(thePath, i)) = False Then
fso.CreateFolder(Left(thePath, i - 1))
End If
If InStr(Mid(thePath, i 1), "\") Then
i = i Instr(Mid(thePath, i 1), "\")
Else
i = 0
End If
Loop
End Sub
