For Resident Evil 4 (2023), the critical backup context is the account-scoped Steam directory. Copying one .bin file without knowing which Steam identity and folder it came from can create a misleading sense that the save is portable. The safer backup is the complete win64_save directory plus a note of the Steam account. On macOS, preserve the entire CAPCOM SaveData directory instead. SaveEditor.com records the user-ID binding because it directly affects restoration and future editor compatibility.
For this PC reference, the documented storage is Windows: Steam: <Steam-folder>userdata<user-id>2050650remotewin64_save | macOS: $HOME/Library/Containers/jp.co.capcom.RE4US/Data/Library/Application Support/CAPCOM/jp.co.capcom.RE4US/SaveData | Linux / Steam Play: Steam Play: <SteamLibrary-folder>/steamapps/compatdata/2050650/pfx/. The known file or folder pattern is win64_save directory records. The 2023 Resident Evil 4 remake stores Steam PC saves in the account-scoped win64_save directory. PCGamingWiki notes that saves are tied to the Steam user ID.
Backup guidance: Back up the complete win64_save directory for Steam, or the complete SaveData directory on macOS. Record the account that created the backup. Steam Cloud is documented for saves and most settings. Launcher and cloud context matters because The Windows/Steam and macOS container paths are different. Keep account/profile context with the backup instead of treating isolated .bin files as anonymous portable saves.
Compatibility and recovery should stay conservative. Steam saves are account-associated. A file from another Steam identity may require a dedicated account-aware conversion workflow; this Game Hub does not claim direct portability. If the expected progress is not visible, If copied saves are ignored, restore the untouched original and confirm account ownership, folder level, and cloud synchronization before attempting another replacement. 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.
