### Details

When you run this sample, a Viewer control containing File and Help menu appears on the top. You can load any of the RDF files from **RDFs** folder using File > Open. An RDF file is a static copy of a report saved to the native Report Document Format. This can be loaded into the Viewer control without running it or accessing data. You can use **Save as RDF** option to save other report formats to RDF format. For more information, see [Save and Load RDF Files](/activereportsnet/docs/v19.2/developers/working-with-reports-devs/section-report-developers/save-load-rdf-files). You can also export to other file formats using File > Export option.
