What is an RGD file?
An .RGD file is a game data file. It most commonly functions as a Raft Saved Game File created by the Raft Developer, Redbeet Interactive. These files store player progress, inventory, and world states. Alternatively, an .RGD file can be a game data configuration file used by the Essence Engine from Relic Entertainment. These are known as Relic Game Data files or Relic Chunky files.
How to open RGD files?
Because .RGD files have multiple possible meanings, we recommend viewer.online/rgd to identify the actual format of your file. viewer.online/rgd analyzes .RGD files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If your file is a Raft save, the Raft game client loads it automatically from the local system save folder.
Software and tools
Players and modders use specific software to modify game files. For Relic configuration files, users rely on modding tools like Corsix's Mod Studio. For Raft saves, players use community save editors or hex editors like HxD to adjust internal values.
Best practices and troubleshooting
Always create a backup of your .RGD file before you edit it. If a game save or configuration file becomes corrupted, the game will crash or fail to load your progress.
Summary
Because .RGD files use the known .NET format, viewer.online/rgd can safely open and display them online, eliminating compatibility problems.
