Where Are Dune: Spice Wars Save Files Located?
Dune Spice Wars saves inside the Steam install under D4X save, with Game Pass copies in AppData instead.
Last updated
Spice Wars breaks the usual rule and saves next to the game itself. Steam builds write into the install folder, under a D4X directory, in a save subfolder. Profile stats files carry per account codes in their names. Options.ini sits beside them.
That placement surprises backup tools that only watch Documents and AppData, so Steam library moves orphan saves. Game Pass builds behave normally by comparison, splitting between the packaged wgs tree and a Roaming folder. Note which store you own before hunting.
Where Dune: Spice Wars stores this, by platform
<SteamLibrary>\steamapps\common\D4X\save
Install relative path, so the drive letter varies. Save files plus profile_stats account files and options.ini live here together.
<SteamLibrary>/steamapps/compatdata/1605220/pfx/
Proton prefix for app ID 1605220. The install relative save path is mirrored inside the prefix drive.
Frequently asked questions
How do I move Dune Spice Wars saves to a new PC?
Copy the whole save folder from the D4X install dir to the same path on the new machine. The profile_stats file carries the account link, so keep it with the saves.
My saves vanished after an update. Where are they?
Check the Recycle Bin first. A Cloud settings change once swept local saves there. Then look in the Roaming Dune folder for the relocated XGS copies.
Where are Game Pass saves for this game?
Look under the FuncomOsloAS package wgs tree and the Roaming Dune folder. Game Pass builds split saves across both, unlike the single Steam folder.
