Help Needed importing, Ungrouping and re-saving .ppf files (like powerpoint)

Hi 

 

I have some old .ppf files which are teaching Slides like a Powerpoint type thing, each file I have has 15-20 pages in and they seem to open in Corel Draw no problem and I have been able to Ungroup also no Problem. But not sure how to put each slide on a separate page (automatically if Possible if not Manually) 

Then I want to re-save as a more modern File that I can open or import to Powerpoint ..

Hope I make sense 

I would Imagine that does not matter that they are a .ppf files as would be the same importing any multipage doc .

 

Any help Is much appreciated 

Cheers Mark
