Solution 1

VB

Dim sr As New IO.FileStream("[copyfrom]", IO.FileMode.Open)
Dim sw As New IO.FileStream("[copyto]", IO.FileMode.Create)
Dim len As Long = sr.Length - 1
Dim buffer(1024) As Byte
Dim bytesread As Integer

While sr.Position < len
    bytesread = (sr.Read(buffer, 0, 1024))
    sw.Write(buffer, 0, bytesread)
    ProgressBar1.Value = CInt(sr.Position / len * 100)
    Application.DoEvents()
End While

sw.Flush()
sw.Close()
sr.Close()

You should try
C:\[floderName]\[filename].[FileType]
D:\[filename].[FileType]

Example :
C:\Windows\Song.mp3
D:\My Music\Song.mp3
