Saving PPTX with embedded file changes embed's file name

It appears that when a PowerPoint (pptx) presentation containing an embedded file is loaded into a Presentation object, and then saved, the file name of the embedded file is mangled.



The attached presentation “Embedded_docx_input.pptx” has a Microsoft Word (docx) file embedded in its only slide. The embedded file’s name is “Microsoft_Word_Document1.docx”.

The attached presentation “Embedded_xlsx_input.pptx” has a Microsoft Excel (xlsx) file embedded in its only slide. The embedded file’s name is “Microsoft_Excel_Worksheet1.xlsx”.



Our application contains code like this (of course, in the actual app inputFile, outputFile and the SaveFormat are not hard-coded):



string inputFile = “C:\foo\Embedded_docx_input.pptx”;

string outputFile = “C:\foo\Embedded_docx_output.pptx”;



try

{

Presentation presentation = new Presentation(inputFile);

using (var outputStream = new FileStream(outputFile, FileMode.Create, FileAccess.ReadWrite))

{

presentation.Save(outputStream, SaveFormat.Pptx);

}

}

catch (Exception ex)

{

// exception handling

}



When I open “Embedded_docx_output.pptx” with WinZip or 7-Zip, I see that the embedded file is now named “oleObject1.docx”.

Similarly, if I run “Embedded_xlsx_input.pptx” through the same code, the embedded file in “Embedded_xlsx_output.pptx” is named “oleObject1.xlsx”.



I get the same results if I first read either input file into a stream, and use the Presentation(Stream) constructor.
