File types and IFilters reference (SharePoint Server 2010)
Aplica-se a: SharePoint Server 2010
Tópico modificado em: 2015-03-09
When crawling content, the crawler uses an IFilter to read individual file types. Some IFilters read only one file type, whereas others can read several file types. If you have to crawl a file type that is not supported by an IFilter that is provided with Microsoft SharePoint Server 2010, you must install and register the appropriate IFilter on the crawl server. The procedures used to install and register IFilters vary among different IFilters. If you want to use an IFilter that is not listed here, contact the manufacturer for instructions for installing third-party IFilters. If you add a file type without registering an IFilter, only the file properties are included in the index.
The following table lists the file types that appear by default on the Manage File Types page in Central Administration and describes whether their corresponding IFilters are registered by default. The table also lists file types that do not appear on the Manage File Types page by default but are supported by default IFilters. You can add these file types without having to register a new IFilter.
File name extension | IFilter supported by default? | File type included by default? |
