RimWorld is a sci-fi video game in which players must build a colony on a world located at the rim of known space. The game has a very active modding community, which distributes both simple and complex mods via the Internet.

Some complex mods require users to load a series of related mods in the correct order. To accomplish this, players must place a modlist, or RML, file in the game's ModLists directory. Each RML file lists a set of mods (which a user must have already subscribed to and installed in their Mods folder) in the order RimWorld must load them for correct gameplay.

How to open an RML file

To use an RML file with the Windows version of RimWorld, place the file in the following directory:

~/​AppData/​LocalLow/​LudeonStudios/​RimWorld by Ludeon Studios/​ModLists

To use an RML file with the Mac version of RimWorld, place the file in the following directory:


(These directory paths may differ if you use the Steam version of RimWorld.)

You can also open an RML file with Microsoft Notepad (Windows), Apple TextEdit (Mac), or any other text editor, to view the modlist it contains.
