What is an RDG file?
A .RDG file is primarily an RDCman Config File created by Microsoft for the Remote Desktop Connection Manager (RDCMan) tool. System administrators use these files to organize multiple remote server connections. The files use a standard XML structure to store server names, logon settings, and group hierarchies.
Another type of .RDG file is a usability study recording created by TechSmith Morae. These files use ZIP compression to store video recordings, audio, and user interaction data from software tests.
Because the .RDG extension has multiple possible meanings, we recommend using viewer.online/rdg to identify the actual format of your file. viewer.online/rdg analyzes .RDG files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open RDG files?
You can open Microsoft .RDG files with Microsoft RDCMan on Windows. Because these files use XML formatting, you can also view them with code editors like Notepad++ or Visual Studio Code.
If your .RDG file is a recording, you need the TechSmith Morae software to view the video and data streams.
Best practices and troubleshooting
Always keep .RDG files secure. Connection manager files often contain sensitive server addresses and login credentials. If your remote connection file becomes corrupted, open it in a text editor to check the XML structure for errors.
Summary
In conclusion, because .RDG files use the known XML format (or standard ZIP compression), viewer.online/rdg can safely open and display them online, eliminating compatibility problems.
