## Steps for Merging PPSX Files in C++

Merge `PPSX` files with [Aspose.Slides for C++](/slides/cpp/) by cloning slides from one presentation into another.

Load the destination and source `PPSX` files with the `Presentation` class.

Iterate through the source slides with `get_Slides`.

Add each slide to the destination presentation with `AddClone`.

Save the merged file with `SaveFormat::Ppsx`.

### Merge PPSX Files - C++

```cpp
auto destinationPresentation = MakeObject<Presentation>(u"first.ppsx");
auto sourcePresentation = MakeObject<Presentation>(u"second.ppsx");

for (auto&& slide : sourcePresentation->get_Slides())
{
    destinationPresentation->get_Slides()->AddClone(slide);
}

destinationPresentation->Save(u"merged.ppsx", SaveFormat::Ppsx);
sourcePresentation->Dispose();
destinationPresentation->Dispose();
```

## About Aspose.Slides for C++ API

 The Aspose.Slides API can read, write, manipulate, and convert Microsoft PowerPoint presentations to PDF, XPS, HTML, TIFF, ODP, and other supported formats. You can create presentations from scratch and save them in a supported output format. Aspose.Slides is a standalone API for creating, parsing, and manipulating presentations, slides, and their elements; it does not require Microsoft PowerPoint or OpenOffice.

A PPSX file is a PowerPoint Open XML Slide Show created by Microsoft PowerPoint 2007 or later. It is the Open XML successor to the PPS format used by PowerPoint 97–2003. Unlike a PPTX file, which opens in editing mode by default, a PPSX file opens directly as a slide show. It preserves the presentation's slide order and can contain images, audio, and other embedded media.
