Where Are Homeworld 3 Save Files Located?
Homeworld 3 follows Unreal Engine 4 layout, with saves in Local Homeworld3 SaveGames and configs beside them.
Last updated
Homeworld 3 uses standard Unreal Engine 4 paths. Campaign and skirmish saves (.sav plus .hwsg sidecars) sit in Local Homeworld3 Saved SaveGames. Graphics and input configs sit beside them under Saved Config WindowsNoEditor. The Steam install folder holds neither.
Steam Cloud mirrors the same tree, and Proton on Linux reflects it under compatdata 1840080. Back up the whole Saved folder before patches, since balance updates occasionally invalidate older skirmish states. Denuvo left in late 2024, so offline restores behave normally.
Where Homeworld 3 stores this, by platform
%LOCALAPPDATA%\Homeworld3\Saved\SaveGames
Configs in Saved\Config\WindowsNoEditor beside it. Copy the parent Saved folder whole for migration so profiles travel with progress.
~/.local/share/Steam/steamapps/compatdata/1840080/pfx
Proton mirror of the Windows pattern above. Exact path may vary by library location, check libraryfolders.vdf on multi library setups.
Frequently asked questions
Does Homeworld 3 use Steam Cloud?
Yes for the Windows paths above. Keep manual Saved folder copies too, since cloud conflicts after long War Games sessions can pick the wrong fleet state.
Where are Homeworld 3 settings stored?
Under Saved Config WindowsNoEditor as standard Unreal INIs. Tweak FOV and upscaling there, keeping a copy before edits in case a patch rewrites them.
