Details

C45Loader and C45Saver use the format employed by the C4.5 algorithm/software, where data is stored in two separate ‘.names’ and ‘.data’ files.

XRFFLoader and XRFFSaver handle XRFF (eXtensible attribute-Relation File Format, an XML-based extension of Weka's native Attribute-Relation File Format) files.
