Where Does Cities Skylines Store Mods?
Cities Skylines mods and assets live in Addons folders plus Steam Workshop. Save games stay separate per the saves post.
Last updated
Save games hold cities while mods and assets change them. Local files live in Addons subfolders for mods, assets and maps. Workshop subscriptions mirror in the Steam content tree.
The existing saves post covers city files; this one covers the mod side. Enable everything in Content Manager before loading. Missing assets turn buildings into errors rather than crashing.
Where Cities: Skylines stores this, by platform
%LOCALAPPDATA%\Colossal Order\Cities Skylines\Addons\Mods
Local mods, assets and maps in Addons subfolders. Workshop mirrors in the 255710 content tree. Saves sit in the sibling Saves folder per the saves post.
~/Library/Application Support/Colossal Order/Cities Skylines/Addons/Mods
Same Addons interior on Mac. Asset heavy cities load slowly, so keep collections trimmed per project.
~/.local/share/Colossal Order/Cities Skylines/Addons/Mods
Identical layout on Linux under local share. Proton and native builds share the Addons convention.
Frequently asked questions
How do I install Cities mods?
Subscribe on Steam Workshop and enable items in Content Manager. Files land in the workshop content tree for app 255710 plus local Addons below. Keep one collection per city since asset count slows loading.
How do I back up a modded city?
Copy the Addons tree plus the Saves folder from the saves post with the game quit. Local mods travel as folders while subscriptions mirror in Workshop. Removing a road mod deletes its networks, so snapshot the city first.
