Installing Additional Filters

Spirion 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, Spirion can search the file while preserving the format and structure of the file.  Additionally, Spirion can attempt to extract text from any file.  As new, proprietary file types are created that Spirion cannot search while preserving format and structure, additional IFilters may be created to search them.  Using an IFilter rather than relying on Spirion to extract the text from a file will increase the ability to find true positives and reduce false positives.  This is the case because Spirion 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, Spirion 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 Spirion, you may be able to download and install an appropriate IFilter. For example, 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 from the following links:
