Here are the steps to irreversibly delete your world file and/or player data.
1. Log in to the control panel at https://control.low.ms
Step 2: Go to your Rust game server
Step 3: Stop the server.
Step 4: Open the File Manager.
Step 5: Navigate to your current save. By default this is \server\low.ms but yours may be different.
To delete the player data only, delete the player *.db files . This includes blueprints, inventories, positions, etc.
To delete the world data only, enter the 'save' directory (server/low.ms) and delete all files ending with .map and .sav.
To delete both the player and world data, you'd perform both of the two steps above.
