American Truck Simulator Save File Location

Last verified: 2026-10-07

Save file location (Windows (local profile)): %USERPROFILE%\Documents\American Truck Simulator\profiles

Quick answer: On PC, American Truck Simulator stores your saves in C:\Users\<you>\Documents\American Truck Simulator\profiles\ — each profile is a hex-named folder holding numbered save subfolders with .sii files. This is NOT the Steam install folder. If Steam Cloud is on, a synced copy also lives under Steam\userdata\<SteamID>\270880, and cloud profiles use the separate steam_profiles folder next to profiles. Copy the whole American Truck Simulator folder before updating, modding, or moving PCs.
Windows (local profile)
%USERPROFILE%\Documents\American Truck Simulator\profiles
Windows (Steam Cloud profile)
%USERPROFILE%\Documents\American Truck Simulator\steam_profiles
Steam Cloud copy
Steam\userdata\<SteamID>\270880

Like its twin Euro Truck Simulator 2, American Truck Simulator keeps your career saves in your Documents folder, not in the Steam install. Here is the exact PC path, how to open it, and how to back it up before a bad cloud sync or a profile loss.

Save file locations

Windows (local profile)
%USERPROFILE%\Documents\American Truck Simulator\profiles

Full default: C:\Users\<you>\Documents\American Truck Simulator\profiles\ . Each profile is a hex-named folder; saves are numbered subfolders containing game.sii. The parent folder also holds .bak backups made at game updates — restore a profile by copying a .bak folder's contents back in.

Windows (Steam Cloud profile)
%USERPROFILE%\Documents\American Truck Simulator\steam_profiles

Cloud-enabled profiles live in steam_profiles, not profiles. If your career looks missing, check both folders.

Steam Cloud copy
Steam\userdata\<SteamID>\270880

With Steam Cloud on, a mirrored copy syncs under app ID 270880. Keep ATS saves off OneDrive-synced Documents to avoid corruption.

Cloud saves

American Truck Simulator supports Steam Cloud. Cloud profiles are stored in the steam_profiles folder and mirrored under Steam\userdata\<SteamID>\270880, syncing on launch/exit. A corrupted or half-written profile can overwrite a good cloud copy, so keep a manual copy of the whole Documents\American Truck Simulator folder as your real backup.

Cloud save conflict & platform recovery

Common loss: 'my career/trucks rolled back' after a crash or a session on a second PC — Steam Cloud synced an older profile over the newer local one.

  1. Before relaunching after a crash, copy %USERPROFILE%\Documents\American Truck Simulator somewhere safe (outside OneDrive).
  2. If the cloud rolled progress back, disable Steam Cloud for ATS in its Properties (or go offline) before launching.
  3. Restore your copied profiles/steam_profiles folder, launch once offline to confirm, then re-enable cloud so the good save uploads.

Save problems & fixes

FAQ

Where is the American Truck Simulator save file on PC?

In C:\Users\<you>\Documents\American Truck Simulator\profiles\ (or steam_profiles for cloud profiles) — not the Steam install folder. Saves are .sii files in numbered subfolders.

Does American Truck Simulator use Steam Cloud?

Yes. Cloud profiles live in the steam_profiles folder and mirror under Steam\userdata\<SteamID>\270880. A bad local profile can overwrite the good cloud copy, so keep a manual backup.

How do I move my ATS saves to a new PC?

Copy the whole Documents\American Truck Simulator folder to the same path on the new PC before first launch, or let Steam Cloud sync a cloud profile.

Why did my ATS career roll back?

Usually a Steam Cloud conflict after a crash or a second-PC session. Restore your folder backup, launch offline to confirm, then re-enable cloud.
