Complex format is not supported with the doc file be created by WPS Office app

Hi there,

I have a doc file (test file - save_as_wps.doc) be created by the WPS Office app that syncfusion can't read the file and throw exception: 

System.NotImplementedException: Complex format is not supported

   at Syncfusion.DocIO.ReaderWriter.WordReader.ReadDocumentHeader (Syncfusion.DocIO.Portable, Version=20.1200.0.58, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89)

   at Syncfusion.DocIO.DLS.DocReaderAdapter.Read (Syncfusion.DocIO.Portable, Version=20.1200.0.58, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89)

   at Syncfusion.DocIO.DLS.WordDocument.OpenInternal (Syncfusion.DocIO.Portable, Version=20.1200.0.58, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89)

If I save as this file by Microsoft Office 365 app, syncfusion works fine (test file - save_as_ms.doc). Please help me to review these files (please refer to the attachment).

Hi Tuong,

On further validating the reported issue, we have found that the given document (test file - save_as_wps.doc) containing incremental save information.

Essential DocIO process the content that are preserved in the last complete save operation alone from a Word (.doc) document and it doesn’t process the incremental save information. Hence it throws “Complex format is not supported” exception when attempting to open a Word (.doc) document containing incremental save information.

To open a Word (*.doc) document containing incremental save information without exception, we suggest you to use SkipIncrementalSaveValidation API value as true before opening a Word document.

For more information and code example, please refer the below link.

Hi Suriya Balamurugan,


I use SkipIncrementalSaveValidation as you suggest, and it works fine.


Many thanks,

Tuong.
