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.
Start with the least destructive explanation
When Persona 4 Golden progress appears missing, first verify the active PC location: Windows: Steam: <Steam-folder>userdata<user-id>1113000remote ; Microsoft Store: %LOCALAPPDATA%PackagesSEGAofAmericaInc.D0cb6b3aet_s751p9cej88mtSystemAppDatawgs<user-id>. Expected files/folders: Steam commonly uses dataXXXX.bin with corresponding dataXXXX.binslot metadata; cloud metadata also resides in the remote directory.. Many apparent save failures are actually profile, storefront, path-redirection, or cloud-selection problems rather than damaged game data.
Preserve every surviving copy
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. Before renaming, moving, replacing, or opening candidate backups, copy them outside the live directory. Do not use the only surviving file as the test specimen for repair or editing.
Check launcher and cloud state
Storefront context: 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. Cloud notes: Steam Cloud and Xbox Cloud are documented. A sync client can reintroduce an older or newer version after a manual restore, so recovery work should keep local and cloud copies conceptually separate until the wanted progress is confirmed.
Use format and compatibility clues
Steam stores the save set under app ID 1113000. Community-documented Vita/PC and edited-save workflows note a checksum relationship between dataXXXX.bin and dataXXXX.binslot. Microsoft Store uses WGS. 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 the file exists but is ignored, compare the complete directory structure, slot/profile naming, game edition, mods/DLC, and any companion metadata. Do not assume an extension change or generic checksum tool can repair a game-specific container.
Game-specific troubleshooting
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. If a known-good backup works, preserve it and create a fresh in-game save before further experiments. If no copy works, prefer read-only inspection and source-backed game-specific tooling over repeated writes.
