Transport Fever 3 (Paradox, 2026) stores your maps and logistics networks in the Steam userdata folder and an %APPDATA% mirror — not in Documents. Here is exactly where the save folder lives, how Steam Cloud can overwrite it, and how to move to a new PC or Steam Deck.
Save file locations
C:\Program Files (x86)\Steam\userdata\<YourSteamID>\3493540\local\save\
App ID 3493540. This is the primary folder Steam Cloud syncs. If you have multiple Steam accounts there will be several numbered userdata folders — the one containing 3493540 is yours.
%APPDATA%\Transport Fever 3\
Full path C:\Users\<YourName>\AppData\Roaming\Transport Fever 3. Check here if the Steam userdata folder looks empty, or for the settings/mods folders alongside the save data.
~/.steam/steam/userdata/<YourSteamID>/3493540/local/save/
Under Proton the Windows path is routed here. Steam Cloud carries your desktop empire to the Deck automatically once both are signed into the same account.
~/Library/Application Support/Transport Fever 3/
Mac builds keep local save data under Application Support. Back this folder up before verifying game files or reinstalling.
Cloud saves
Transport Fever 3 uses Steam Cloud (App ID 3493540), so your maps and logistics networks mirror to Steam and download on any machine you sign into — including a Steam Deck. The catch common to sim games: if the cloud copy is older or empty after a crash, it can overwrite a newer local save on next launch. Before restoring a backup or moving PCs, set the game to offline / disable Steam Cloud for Transport Fever 3, copy your local\save folder, then re-enable it.
How to open the save folder
- Press Win + R to open the Run box.
- Type %APPDATA%\Transport Fever 3 and press Enter to reach the local data, or open Steam → right-click Transport Fever 3 → Manage → Browse local files for the install.
- For the Cloud save, open C:\Program Files (x86)\Steam\userdata\<YourSteamID>\3493540\local\save and copy the whole save folder to a USB drive or cloud storage.
- To move to a new PC: install Transport Fever 3, launch once so the folders are created, close the game, then paste your backed-up save files over the new save folder (or just let Steam Cloud sync).
FAQ
Where is the Transport Fever 3 save file on PC?
In the Steam userdata folder at ...\userdata\<YourSteamID>\3493540\local\save\ (Steam Cloud), with a local mirror at %APPDATA%\Transport Fever 3. It is NOT in the Documents folder, which is where many players first look.
How do I back up or move my Transport Fever 3 saves?
Copy the whole save folder from the Steam userdata path (or %APPDATA%\Transport Fever 3) to a USB drive or cloud storage. On a new PC, install the game, launch once, close it, then paste the files back — or sign into Steam and let Steam Cloud restore them.
Why can Steam Cloud overwrite my Transport Fever 3 save?
If the cloud copy is older or empty (e.g. after a crash or on a fresh PC) it can sync over your good local save on launch. Disable Steam Cloud for the game before restoring an older backup, then copy your files, then re-enable it.
