    Use the following code
    Code:
    Dim sBucket As String
    Dim LenFile1 As Long
    Dim i As Integer
    
    Open "c:\file.bin" For Binary As #1
    LenFile1 = LOF(1)
    
    i = 1
    
    Do While Not EOF(1)
        Select Case (LOF(1) - Loc(1))
            Case Is >= 2048
                Dim filename As String
                filename = "C:\temp" + i + ".bin"
                i = i + 1
                sBucket = String(2048, " ") 'Copy 2K at a time.
                Open filename For Binary As #2
            Case 0
                Exit Do 'end of file
            Case Else
                sBucket = String(LOF(1) - Loc(1), " ") 'Amount left is smaller then 2K so grab it
        End Select
    
        Get 1, , sBucket  'get data from file 1
        Put 2, , sBucket  'put data to file 2
    Loop
    
    Close #1
    Close #2
