Hello I found the answer. Following VBA code from John is giving me the right answer. For your information.



Sub splitFiles()
Dim tempR As Presentation
Dim opres As Presentation
Dim L As Long
Dim oFolder As String
'requires v. 2010 or later
On Error Resume Next
Set opres = ActivePresentation
Set tempR = Presentations.Add
tempR.PageSetup.SlideSize = opres.PageSetup.SlideSize
oFolder = Environ("USERPROFILE") & "\Desktop\Files\"
MkDir oFolder
For L = 1 To opres.Slides.Count
opres.Slides(L).Copy
tempR.Windows(1).Panes(1).Activate
Call CommandBars.ExecuteMso("PasteSourceFormatting")
Call tempR.SaveCopyAs(oFolder & "Slide" & CStr(L) & ".pptx", ppSaveAsOpenXMLPresentation)
tempR.Slides(1).Delete
Next L
tempR.Saved = True
tempR.Close
End Sub
