Hi Vijay,

I have observed the code snippet shared by you and have found inconsistency in that. You are actually trying to save PPT as PPTX using Aspose.Slides for Java. This feature is unavailable in Aspose.Slides for Java. The file that you have saved is in fact internally PPT but named as PPTX. If you ought to convert PPT to PPTX then please do this through PowerPoint.

Many Thanks,
