Octopath Traveler uses a clear SaveGames directory on the conventional Steam PC build, but the user-ID layer and numbered slot names are important when restoring progress. Community guides consistently identify SaveData0.sav as the autosave and subsequent numbered files as manual slots. SaveEditor recommends backing up the entire directory so slot context and Steam cloud metadata remain available. Microsoft Store uses WGS, so its files are described as a separate container rather than an ordinary .sav location.
For this PC reference, the documented storage is Windows: Steam: %USERPROFILE%DocumentsMy GamesOctopath_Traveler<user-id>SaveGames ; Microsoft Store: %LOCALAPPDATA%Packages39EA002F.FrigateMS_n746a19ndrrjgSystemAppDatawgs. The known file or folder pattern is SaveData0.sav is commonly the autosave; numbered SaveData*.sav files represent manual slots on Steam.. The Steam release uses an Unreal-style Documents SaveGames directory under a user ID. Microsoft Store uses WGS. Slot numbering matters when replacing a particular save.
Backup guidance: Back up the full SaveGames folder, including every SaveData*.sav and steam_autocloud.vdf if present. Keep the original slot numbering when testing a restore. Steam Cloud and Xbox Cloud are documented; OneDrive may also synchronize Documents. Launcher and cloud context matters because Storefront paths differ. Steam/Epic PC save data can resemble ordinary .sav files while Microsoft Store uses WGS containers.
Compatibility and recovery should stay conservative. Switch/PC and Microsoft/Steam transfers reported by the community are migration workflows, not proof that all storefront containers are byte-identical. If the expected progress is not visible, If a save does not appear, verify the user-ID folder, exact SaveData slot number, and cloud state. For Microsoft Store, identify the correct WGS payload before any conversion. SaveEditor.com only labels a game-specific editor as available when a separate linked Tool has a verified operational runtime; this reference page by itself is not an editor claim.
