VB CODE to save file unique name

[ateebali]

I am using following vb code to save file with cell range;

Dim Path As StringDim filename As String
Path = ThisWorkbook.Path & "\Backup" & ""
filename = Range("O6")
ActiveWorkbook.SaveAs filename:=Path & filename & ".xlsb", FileFormat:=50
Application.DisplayAlerts = False

I need to amend it that if file already save with this name, it should save the file with extension for example, if file name ABC.xlsb already there, it saves as ABC (1)

I have tried this but its not working;

Dim Path As StringDim fileName As String
If Dir(ThisWorkbook.Path & "\Backup", vbDirectory) = vbNullString Then MkDir ThisWorkbook.Path & "\Backup"
Path = ThisWorkbook.Path & "\Backup" & ""


fileName = Range("O6")
ActiveWorkbook.SaveAs fileName:=Path & fileName & ".xlsb", FileFormat:=50
Application.DisplayAlerts = False


End Sub


Function GeneratedFileName(fileName As String, i As Integer)
Dim testFileName As String
testFileName = fileName
If i <> 0 Then
testFileName = fileName & " (" & i & ")"
End If
GeneratedFileName = testFileName
If Dir(testFileName & ".xlsb", vbNormal) > "" Then
GeneratedFileName = GeneratedFileName(fileName, i + 1)
End If


End Function
