Transport Fever 3 stores its save files at C:\Program Files (x86)\Steam\userdata\<your Steam ID>\3493540\local 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 Transport Fever 3 saves are stored
- Windows —
C:\Program Files (x86)\Steam\userdata\<your Steam ID>\3493540\local
or%APPDATA%\Transport Fever 3 - macOS —
~/Library/Application Support/Transport Fever 3 - Linux —
~/.local/share/Transport Fever 3
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).

Backing up Transport Fever 3 saves automatically
- Install Checkpoint64 (free) and pick Transport Fever 3 — the save path above is already preset.
