What Are IFilters?
IFilters are third-party converters used by CES to index document types not supported
by its default or open converters. Adding IFilters to a document type set is a quick
and easy way to increase the number of document types indexed by CES. However, IFilters
produce larger files and poorer resolutions than CES converters.
Note: The default CES converters support the document types listed in Supported File Formats.
