Box Destination Path

I would like to choose destination path when user download file on her computer. I have code for the download, but I don't find code or component for change the destination on the Save in box.

The code:

Set objFile = objFSO.GetFile(strFileName)
Response.Clear()
Response.AddHeader "Content-Disposition", "attachment; filename=" &
objFile.Name
Response.AddHeader "Content-Length", objFile.Size
Response.ContentType = "application/octet-stream"
Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.Type = 1
Response.CharSet = "UTF-8"
objStream.LoadFromFile(strFileName)
Response.BinaryWrite(objStream.Read)
objStream.Close
Set objStream = Nothing
Set objFile = Nothing
