Sea of Stars Save File Location

Last verified: 2026-10-08

Save file location (Windows (Steam / Epic / GOG)): %USERPROFILE%\AppData\LocalLow\Sabotage Studio\Sea of Stars

Quick answer: On PC, Sea of Stars stores saves at C:\Users\<you>\AppData\LocalLow\Sabotage Studio\Sea of Stars\ , as .sos files — SOS_SaveSlot0.sos for the first slot, SOS_SaveSlot1.sos for the next, and so on. The fastest route is Win+R, paste %USERPROFILE%\AppData\LocalLow\Sabotage Studio\Sea of Stars and press Enter (AppData\LocalLow is hidden by default). Copy the whole Sea of Stars folder to back up every slot.
Windows (Steam / Epic / GOG)
%USERPROFILE%\AppData\LocalLow\Sabotage Studio\Sea of Stars
Steam Cloud copy
Steam userdata (managed by Steam)

Sea of Stars tucks its saves into the hidden LocalLow AppData tree as .sos slot files, a spot Explorer hides by default — which is why players think the save vanished when it's really just hidden. Here is the exact PC path, how to open it, and how to back it up.

Save file locations

Windows (Steam / Epic / GOG)
%USERPROFILE%\AppData\LocalLow\Sabotage Studio\Sea of Stars

Full default: C:\Users\<you>\AppData\LocalLow\Sabotage Studio\Sea of Stars\ . Saves are SOS_SaveSlotN.sos. AppData\LocalLow is hidden — use the Run box or enable Show hidden files.

Steam Cloud copy
Steam userdata (managed by Steam)

The Steam version syncs via Steam Cloud on launch/exit. A corrupted local .sos can overwrite the good cloud copy, so keep a manual backup.

Cloud saves

The Steam version of Sea of Stars syncs saves to Steam Cloud on launch and exit. Because a bad or half-written .sos can overwrite the good cloud copy the next time you launch, treat a manual copy of the Sea of Stars folder as your real backup.

Cloud save conflict & platform recovery

Common confusion/loss: the save folder looks empty (AppData\LocalLow is hidden), or progress rolls back after a crash when Steam Cloud syncs an older .sos.

  1. Open %USERPROFILE%\AppData\LocalLow\Sabotage Studio\Sea of Stars via the Run box — it only looks missing because the folder is hidden.
  2. Before relaunching after a crash, copy the whole Sea of Stars folder somewhere safe.
  3. If the cloud rolled progress back, disable Steam Cloud for the game (or go offline), restore your .sos file, launch once to confirm, then re-enable cloud.
Back up first (Windows) — copy & run
