How to use the Navicat Report Viewer? (Windows)One of our products, Navicat Report Viewer, allows viewing of report files in .raf and .rtm formats. Although the formats were generated by Navicat, you can share reports with someone who does not have Navicat running on his or her computer but has Navicat Report Viewer installed. In this tutorial, we will show you how to open the .raf and .rtm report files. To open an archive report file, simply click “Open Report” in “File” from the main menu and select the desired file. To view the .rtm report file, first, click on the “Connection” icon to create a new connection to your server. Next, fill the server connection information in the “General” tab. Then, click the “Advanced” tab and select the “Report Location” where the report files are stored. Finally, open the connection and double-click to view a report.
