Default crawl file name extensions and analysis file types in SharePoint 2013

Summary: Learn about the file extensions that SharePoint 2013 crawls by default and the types of files they resolve, so you can learn about the files and supported features that search can crawl.

If the list on the Manage File Types page contains a file name extension, the crawl component will crawl only the files. Content processing components can only parse the contents of a crawl file:

• When it has a format handler that resolves the file format.
• When you use a format handler to resolve files that have file formats and file name extensions.

By default, SharePoint 2013 meets these requirements for many file types.

Default crawl file name extension and parsing file format

The following table shows all the file formats that SharePoint 2013 has a built-in format handler for. The table displays one or more format IDs and file name extensions for each file format. By default, SharePoint 2013 is enabled to resolve files that have these file formats and file name extensions. For each file name extension, the table also indicates whether the file name extension is listed by default on the Manage File Types page.
