I'm evaluating Spire.Doc to update Word documents stored in SharePoint. I am able to update the documents just fine but when I save the document the SharePoint metadata is removed from the doc. When viewing in Word, the properties are shown under the "Properties" section and they are not present in the CustomDocumentProperties properties.
If I unzip the unmodified DOCX file, the SharePoint metadata is stored in the /customXML folder as so:
item1.xml - contains information about the columns
item2.xml
item3.xml
item4.xml - contains the actual column values
When I unzip the DOCX file I modified with Spire.Doc that folder has been removed.
Is there a way to re-add these properties or, even better, to save the document without removing those properties?
Thank you,
Jason
