How to create a custom storage plug-in
File Classification Infrastructure (FCI) uses storage plug-ins or modules to store classification properties files. A few modules are provided by the system, including a plug-in to store properties in Office files. If properties need to be stored within other file types, a custom storage plug-in can be created.
Storage modules are queried when FCI reads properties for a file as well as when it writes properties for a file. Each plug-in can indicate which file extensions it can support.
