Svante Schubert commented on ODFTOOLKIT-327:
--------------------------------------------

If you add one of those problematic files to the issue, I might debug into it.
PS: Although the Simple API is created by IBM and should be maintained by them, the stack goes to the lower layer, I am curious upon.

Best regards,

> Hello guys I'm facing an issue when I try to load an odp file, researching in the web seems like the only solution is to open those files and save it. But I cannot do that I'm running a batch process which mean  that I will process many files.

> 		org.odftoolkit.simple.Document document = PresentationDocument.loadDocument(documentToExtract);
> 	}
