Specified part does not exist in the package

Question

I have the following code: ``` using (var doc = WordprocessingDocument.Open(filename, true)) { .... } ``` Where string filename is a valid path to a docx file. But calling Open causes the following InvalidOperationException: `Specified part does not exist in the package.` Edit: I assume the problem is due to the docx file I'm trying to open being invalid so I'll post the xml: ``` <?xml version="1.0" encoding="utf-8" standalone="yes"?> <w:document xmlns:wpc="http://schemas.microsoft.com/office/word/2010/wordprocessingCanvas" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officeDocument/2006/math" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:wp14="http://schemas.microsoft.com/office/word/2010/wordprocessingDrawing" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing…

Accepted Answer

As it turns out the problem was due to a missing xml file. In case anyone else runs into similar problems, check the following:

- rename yourfile.docx to yourfile.zip

- extract the zip file and look in the file called `[Content-Types].xml`

- check that all the xml files listed in `[Content-Types].xml` exist in your zip file.

In my case I had the following line in my `[Content-Types].xml` file:

```
<Override PartName="/word/recipientData.xml" ContentType="application/vnd.ms-word.mailMergeRecipientData+xml"/>
```

But I was missing the `recipientData.xml` file from the word directory.
