Identity Finder can already search more than 200 of the most common file types using its built-in filters and a built-in feature of Microsoft Windows available since Windows 2000 called IFilters. For these filterable file types, Identity Finder can search the file while preserving the format and structure of the file. Additionally, Identity Finder can attempt to extract text from any file. As new, proprietary file types are created that Identity Finder cannot search while preserving format and structure, additional IFilters may be created to search them. Using an IFilter rather than relying on Identity Finder to extract the text from a file will increase the ability to find true positives and reduce false positives. This is the case because Identity Finder uses the context and structure of files to look for specific types of information and determine if a potential match is truly personal information. If you install any of these additional IFilters, Identity Finder will automatically detect and utilize them for all of your future searches.
If the filter for a file type you want to search is not already built into Identity Finder, you may be able to download and install an appropriate IFilter. To learn more about IFilters or to download one, visit Microsoft's IFilter website. For more information, you can also visit IFilter.org.
To enable searching of Microsoft OneNote files and/or Microsoft Visio files without having to install those applications, you may download and install Microsoft's Filter Pack for free. It is available here:
