Cities: Skylines II stores its save files at %USERPROFILE%\AppData\LocalLow\Colossal Order\Cities Skylines II\Saves on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps earlier versions, so a corrupted or overwritten save is one click from restored.
Where Cities: Skylines II saves are stored
- Windows —
%USERPROFILE%\AppData\LocalLow\Colossal Order\Cities Skylines II\Saves
orC:\Program Files (x86)\Steam\userdata\<your Steam ID>\949230\remote
Where two locations are listed, which one is in use depends on the install (Checkpoint64 checks them in order and uses the first that exists).
Not sure where yours is? The Steam Save File Location guide explains how that path is built.
How to open the save folder
- Windows — press Win+R, paste
%USERPROFILE%\AppData\LocalLow\Colossal Order\Cities Skylines II\Saves, and press Enter (the AppData folder is hidden in Explorer, which is why this path is so easy to miss — pasting it skips the hunt).
Backing up Cities: Skylines II saves automatically
- Install Checkpoint64 (free) and pick Cities: Skylines II — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
