Step 1: Create an empty folder on a cloud.
Any cloud service can be used here. I used OneDrive because it comes with Windows and requires zero setup. To create an empty folder in you OneDrive cloud, simply access it through the Windows File Explorer.


Step 2: Copy your Mod configuration files from local RimWorld directory to the cloud folder.
You can find your local RimWorld configuration files at C:\Users\<username>\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios
You should see a folder named 'Config' under this directory. Copy everything in there into the cloud folder you just created.

From now on the cloud folder is supposed to hold your latest Mod configuration files. Follow the next section for setup steps on each PC.

With the cloud folder created and updated with configuration files, you want your game to look up and update that folder from here on, instead of the local directory where the game looks for Mod configuration. On each PC, you need to create a symbolic link from the local directory to the cloud directory we just created.

To do this, run Windows Command Prompt as admin, and follow these steps. Quick note: your Windows username is likely different from mine, but the rest part should look the same unless you have changed default RimWorld file directories.

1. Navigate to the local RimWorld directory.

C:\Windows\System32>cd /d %appdata%

C:\Users\catty\AppData\Roaming>cd "..\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios"

C:\Users\catty\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios>

2. Delete the existing 'Config' folder under current directory if it does. By now its content should have been uploaded to your cloud folder of choice, but it doesn't hurt making a backup of this folder before deleting it. Proceed at your own risk if you choose not to make a backup.

You can use a command to delete the folder, or simply type "start ." to open the graphical file explorer if you are more comfortable with it.

3. Make the symbolic link.

C:\Users\catty\AppData\LocalLow\Ludeon Studios\RimWorld by Ludeon Studios>mklink /d "Config" "C:\Users\catty\OneDrive\Rimworld Mods"
symbolic link created for Config <<===>> C:\Users\catty\OneDrive\Rimworld Mods

Essentially, you have 'tricked' RimWorld to look up instead the cloud folder for Mod configuration. Once this is done to all your PC's you no longer have to worry about manually synchronizing or even worse, memorizing your Mod configuration for a consistent experience across PC's.

Just play the game. Every time you run RimWorld on any of the PC's with this setup, the game essentially refers to the same cloud folder, where it loads configs from and saves them to. It doesn't matter which PC you play on as long as internet connection remains uninterrupted throughout your play.

If you have any questions please leave a comment. I did not go into every possible technical detail on maneuvering your PC since they can be found on the internet, but if there are frequently asked question I'll update guide to cover those.
