Ultimate Guide to RimWorld Multiplayer Save Location Sharing

Locating your RimWorld multiplayer save file is the first critical step when coordinating a session with friends or migrating a world between machines. Because the game does not inherently sync progress to a cloud service, the save file acts as the single source of truth for your colony's story, and understanding its storage location is essential for collaboration.

Understanding RimWorld's Save Architecture

Before diving into specific paths, it is important to understand how RimWorld structures its data. The game separates permanent settings and mods from the actual save file itself. When you host a multiplayer game, the host's computer acts as the server, and all participants connect to that specific instance, making the host's local folder the authoritative location for that campaign.

Default Save Locations by Platform

The directory where RimWorld stores your colony data varies depending on your operating system. Users on Windows, macOS, and Linux will find their files organized according to standard application protocols, even though the naming conventions differ slightly.

Accessing the "Saved" Folder

Within the main directory outlined above, you will find a folder labeled "Saved." This is the RimWorld multiplayer save location in its purest form. Inside, you will see a file with the extension .rws (RimWorld Save) and a corresponding folder of the same name containing the map's raw data.

If you are hosting the game, ensure that your friends are sharing the exact same file path. If you are joining a friend's game, you generally do not need to place the save file in your own "Saved" folder; the host's IP address and port number handle the connection. However, if you wish to join an offline session or back up the world, manually copying this .rws file is necessary.

Differences Between Host and Client Caches

It is common for players to look at their Steam or launcher cache folders and become confused when they do not see the colony data there. The download cache, often located in the Steam installation directory, contains the game's executable and assets, but not your personal colony.

Your actual RimWorld multiplayer save location is distinct from this cache. The host's machine writes temporary verification data to a local cache, but the definitive save state remains in the Documents/My Games/RimWorld/Saved folder. If you are attempting to troubleshoot a corrupted save or verify file integrity, focus your attention on the "Saved" directory rather than the Steam download folder.

Sharing Saves Across Different Machines

One of the most frequent technical hurdles in RimWorld multiplayer is moving a save file from one computer to another. Simply copying the .rws file is usually sufficient; however, you must ensure that the game version matches exactly across all devices. A mismatch in patch versions can cause the save to fail to load or result in desynchronization errors during play.

When transferring the file, paste it into the "Saved" folder on the new machine, preserving the original folder name. This ensures that the game recognizes the world and loads the associated metadata correctly, allowing your multiplayer campaign to resume seamlessly.
