Persona 4 Golden illustrates why a save “slot” can be more than one file. Steam stores data under app ID 1113000, and documented cross-platform workflows pair each dataXXXX.bin with a companion .binslot structure whose checksum may need to agree. A backup of only the visibly largest file is therefore incomplete. SaveEditor recommends copying the whole remote directory first, then treating any conversion or editor workflow as a separate operation on duplicates. Microsoft Store is again represented by WGS and is not presented as drop-in compatible.
Which storefront context matters
Documented Persona 4 Golden PC launchers/storefronts: Steam, Microsoft Store. A .bin slot and its .binslot metadata should be treated as a pair. Microsoft Store WGS transfer is a separate conversion problem, not a simple rename. The active storefront/account should be identified before any restore because cloud and local storage may not use the same path or container across editions.
Documented cloud behavior
Steam Cloud and Xbox Cloud are documented. Cloud synchronization is useful for continuity, but it can also turn a restore into a conflict-resolution event. Let synchronization settle before making a manual backup, and keep an offline copy outside any folder monitored by the launcher or operating-system sync service.
Local save roots still matter
The researched local save boundary is Windows: Steam: <Steam-folder>userdata<user-id>1113000remote ; Microsoft Store: %LOCALAPPDATA%PackagesSEGAofAmericaInc.D0cb6b3aet_s751p9cej88mtSystemAppDatawgs<user-id>; the known file or folder pattern is Steam commonly uses dataXXXX.bin with corresponding dataXXXX.binslot metadata; cloud metadata also resides in the remote directory.. A cloud-enabled game still has concrete local data involved in ordinary play, and that local context is what you need when identifying which copy was modified most recently.
Avoid accidental overwrite loops
Back up the entire 1113000remote directory before changing a slot. Preserve the matching .bin/.binslot files and cloud metadata together so the original pairing can be restored. When restoring, close the game and launcher, preserve both the current local copy and the backup you want to test, then place the intended data in the matching profile/storefront location. Do not repeatedly open the game between different copies without noting which side the cloud client selected.
Compatibility and conflict checks
Edited or cross-platform slot data can fail if companion checksum metadata no longer matches. Avoid mixing a .bin from one snapshot with a .binslot from another. If progress disappears or rolls back, If a slot warns or fails to load, restore the matching pair. When moving from Microsoft Store, verify the transfer workflow for the current game version instead of treating WGS blobs as Steam files. Resolve identity/path/cloud questions first. A cloud conflict is not proof that the save itself is corrupt, and a successful upload is not proof that files from another storefront are compatible.
