## **FAQ**

### What presentation formats are supported when extracting Flash content?

[Aspose.Slides supports](/slides/net/supported-file-formats/) the main PowerPoint formats such as PPT and PPTX, since it can load these containers and access their controls, including Flash-related ActiveX elements.

### Can I convert a presentation with Flash to HTML5 and preserve Flash interactivity?

No. Aspose.Slides does not execute SWF content or convert its interactivity. While export to [HTML](/slides/net/convert-powerpoint-to-html/)/[HTML5](/slides/net/export-to-html5/) is supported, Flash will not play in modern browsers due to end of support. The recommended path is to replace Flash with alternatives such as video or HTML5 animations before export.

### From a security perspective, does Aspose.Slides execute SWF files while reading a presentation?

No. Aspose.Slides treats Flash as binary data embedded in the file and does not execute SWF content during processing.

### How should I handle presentations that include Flash along with other embedded files via OLE?

Aspose.Slides supports [extracting embedded OLE objects](/slides/net/manage-ole/), so you can process all related embedded content in one pass, handling Flash controls and other OLE-embedded documents together.
