It consists of a groveller service and a sis.sys filter driver. The service detects duplicate files and replaces them with SIS reparse points on NTFS which trigger action by the sis.sys filter driver. For the feature to work on a given volume, the sis.sys filter needs to be active on the volume. - Danilo -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
