Cities: Skylines stores its save files at %LOCALAPPDATA%\Colossal Order\Cities_Skylines\Saves on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps every version, so a corrupted or overwritten save is one click from restored.
Where Cities: Skylines saves are stored
- Windows —
%LOCALAPPDATA%\Colossal Order\Cities_Skylines\Saves - macOS —
~/Library/Application Support/Colossal Order/Cities_Skylines/Saves - Linux —
~/.local/share/Colossal Order/Cities_Skylines/Saves
The save data here is .crp files — back up the folder as a set, not single files, so a restore always keeps them consistent.
