To delete a file type from the content index, you have to remove it from the list of file types that are crawled. After you delete a file type and perform a full crawl, content that has the file name extension that is specified by the deleted file type is no longer in the content index. Therefore, after you delete a file type, you must perform a full crawl to ensure that all previous results returned from that file type are removed from the content index.
Use the following procedure to delete a file type from the content index.
