The SharePoint Portal Server Search service uses Microsoft Windows® 2000 Indexing Service filter technology to filter the contents of documents in the document library and external content sources. You can install a special dynamic-link library (DLL), referred to as an IFilter, to access documents in their native formats. The name 'IFilter' is derived from the name of the Component Object Model (COM) interface that an IFilter implements.

SharePoint Portal Server provides IFilters for common document formats. These include IFilters for text, HTML, Microsoft Office documents, and Tagged Image File Format (TIFF).

Below you can download additional IFilters which enable you to extent the search capabilities of SharePoint Portal Server.
