Octopath Traveler II looks similar to the first game at a glance, but its Steam directory adds an explicit Steam branch and current transfer reports call out SystemData.sav alongside SaveData slot files. That makes whole-folder backup more important than copying a single large slot. SaveEditor records the current Microsoft Store WGS path separately and avoids claiming that a Game Pass blob can simply be renamed into a Steam SaveData file without the system-data context.
Prepare the source PC
On the source system, identify the actual Octopath Traveler II save root: Windows: Steam: %USERPROFILE%DocumentsMy GamesOctopath_Traveler2Steam<user-id>SaveGames ; Microsoft Store: %LOCALAPPDATA%Packages39EA002F.OCTOPATHTRAVELER2_n746a19ndrrjgSystemAppDatawgs. The expected file/folder pattern is SaveData*.sav plus SystemData.sav on current Steam builds.. Close the game, let the active launcher finish writing and synchronizing, then make a complete offline copy rather than transferring a file that may still be open.
Preserve storefront and profile identity
Documented storefronts: Steam, Microsoft Store. Steam and Game Pass storage differ. Current community migration notes identify both slot-sized files and separate system data in WGS. A transfer between two PCs is simplest when both systems use the same storefront/account/profile context. If the destination uses a different store or container, treat that as a migration problem rather than an ordinary restore.
Move the complete save boundary
Copy the whole SaveGames directory on Steam, including SystemData.sav. For Microsoft Store, preserve all WGS containers before identifying slot and system payloads. Put the copied data on the destination only after confirming the destination save path. If the game creates a new empty save first, keep that new folder as another backup so you can compare structures and revert.
Handle cloud sync deliberately
Steam Cloud and Xbox Cloud are documented. Decide whether the local transferred copy or cloud copy should be authoritative before launching the game. If possible, preserve both. After the transferred save loads correctly, make a fresh in-game save and let the launcher synchronize normally.
Check compatibility before blaming the transfer
The sequel uses a Steam-specific Documents branch and separates slot saves from system data. Microsoft Store uses WGS. SystemData should be backed up with the slots because it can contain state not represented by one SaveData file. Compatibility note: Do not restore only one SaveData slot if you are trying to reproduce the complete profile state. Cross-store migration may need both slot and system payload handling. If the destination does not see the transferred progress, If an imported slot seems blank or incomplete, check whether SystemData came from the same snapshot and whether Steam Cloud restored the previous directory. Verify game edition/version, store, profile IDs, redirected folders, and mod/DLC dependencies before editing the save itself.
