select the folder where you want to save the download

Question

Hi all,

i want to download  some files  from server folder  and i want to give option  to client so that he can   select the folder where he  want to save the downloaded files    but  files are downloading in default folder (download)    
 

 Dim strRequest As String = Request.QueryString("file") '-- if something was passed to the file querystring

    If strRequest <> "" Then 'get absolute path of the file

        Dim path As String = Server.MapPath(strRequest) 'get file object as FileInfo

        Dim file As System.IO.FileInfo = New System.IO.FileInfo(path) '-- if the file exists on the server

        If file.Exists Then 'set appropriate headers

            Response.Clear()

            Response.AddHeader("Content-Disposition", "attachment; filename=" & file.Name)

            Response.AddHeader("Content-Length", file.Length.ToString())

            Response.ContentType = "application/octet-stream"

            Response.WriteFile(file.FullName)

            Response.End 'if file does not exist

        Else

            Response.Write("This file does not exist.")

        End If 'nothing in the URL as HTTP GET

    Else

        Response.Write("Please provide a file to download.")

    End If


it is downloding in default folder but i want to give option  to client so that he can   select the folder where he  want to save the downloaded files
