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.
Where Resident Evil 4 stores PC saves
The researched save-location boundary 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. This is the practical starting point because launcher, profile, and storefront context can change which copy is active even when two folders look similar.
Storefront and profile differences
Documented launchers or storefronts: Steam, macOS App Store. 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. When looking for a missing save, identify the executable/storefront you actually launched and the user/profile that created the progress before copying anything between directories.
Cloud synchronization
Steam Cloud is documented for saves and most settings. A cloud service should be treated as another copy of the save, not as proof that the local folder is disposable. Before a manual restore, let synchronization finish, make an offline backup, and avoid starting the game while files are being replaced.
What the files represent
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. The current filename/folder evidence is win64_save directory records. File-extension context: .bin A location guide does not claim that every file in the directory is safe to edit or that files from another storefront are automatically interchangeable.
If the save is not where expected
If copied saves are ignored, restore the untouched original and confirm account ownership, folder level, and cloud synchronization before attempting another replacement. Also check redirected Documents folders, Steam Play prefixes, account IDs, and launcher-specific containers where applicable. Preserve every candidate copy before testing a restore so troubleshooting does not destroy the only surviving version.
