Topic Last Modified: 2007-11-08

This is a list of the file types that are used when creating file filters to detect files based solely on their content type. The program log number is reported in the Forefront Security for SharePoint program log when the associated file type is identified by a virus scanner or a file filter. For more information about detecting files by type, see Filtering by file type in SharePoint file filtering.

OPENXML

83

OpenXML File

NOTE: This file type applies to Word, PowerPoint, and Excel 2007 files only. The Scan Doc Files As Containers settings in General Options (for each scan job) do not apply to Office 2007 files, since these are always scanned as containers. Although OpenXML files are essentially ZIP containers, and the individual files inside are scanned by FSSP, settings that affect ZIP files do not apply to them. OpenXML documents have an XML-based schema which FSSP cannot modify if an infection is found. Therefore, if an infection is in a file that is part of the XML schema, the file is not cleaned and the entire OpenXML document is deleted. However, if the infected file is not part of the XML schema, then FSSP will attempt to clean just that infected file (replacing it with the Deletion Text) and leave the rest of the OpenXML document intact; if it cannot be cleaned, just that file will be deleted. Note that, Office 2007 does not open any OpenXML file containing files that are not part of the XML schema.
