HTTP itself doesn't allow multiple files in the response. As the duplicate question shows, you can zip multiple files and return the zipped file — Panagiotis Kanavos, Sep 04 '18 at 10:46

 Dim i As Integer
    Dim TxtLocalSysName As String = Request.UserHostName
    Dim readStream As FileStream
    Dim writeStream As FileStream
    Try
        For i = 0 To lstdownload.Items.Count - 1
            Dim filePath As String = Me.Label5.Text + "\" + lstdownload.Items(i).Text
            Dim targetFile As System.IO.FileInfo = New System.IO.FileInfo(filePath)
            readStream = New FileStream(filePath, FileMode.Open)
            Dim length As Integer = Convert.ToInt32(readStream.Length)
            'This is the buffer.
            Dim byteFile() As Byte = New Byte(length) {}
            readStream.Read(byteFile, 0, length)
            readStream.Close()
            Dim localPath As String = "\\" & TxtLocalSysName & "\c$\downloads"
            If Not Directory.Exists(localPath) Then
                Directory.CreateDirectory(localPath)
            End If
            writeStream = New FileStream(localPath & "\" & targetFile.Name, FileMode.Create)
            writeStream.Write(byteFile, 0, length)
            writeStream.Close()
        Next i
    Catch ex As Exception
