How to split a PowerPoint 2007 file into multiple PowerPoint 2007 files?

1 slide in the original file = 1 new powerpoint 2007 file

I'have already successfully done this task for other powerpoint files (< 2007).

Thanks

Currently, Aspose.Slides does not support splitting of pptx presentations. But it will support it in near future. Almost 3-4 months from now.

You can copy slides to an another presentation.
Please check release notes for Aspose.Slides for .Net 2.8.7.0 for example.
