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.
Choose the correct backup boundary
For Resident Evil 4, the researched PC save location 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 save file or folder pattern is win64_save directory records. Back up the complete win64_save directory for Steam, or the complete SaveData directory on macOS. Record the account that created the backup. Copying the complete documented save boundary is safer than selecting one visually obvious file, because companion metadata, indexes, backups, or multiple slots can be required together.
Make an offline copy before changing anything
Close the game first, wait for the active launcher to finish writing, then copy the save data to a separate folder that the game and sync client do not watch. Label the copy with the game, storefront, profile, and date. Documented launcher context: 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.
Account for cloud saves
Steam Cloud is documented for saves and most settings. Before restoring an older backup, decide which copy should win. If the game or launcher starts while an older manual copy is in place, synchronization can replace it before you confirm that it works. Keep the untouched backup outside the live save path until the restored progress has been opened and saved normally.
Restore without changing format assumptions
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. Compatibility note: 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. Restore into the matching storefront/profile context whenever possible. Do not rename a save extension, move a folder into a different container type, or assume a console/mobile copy is equivalent unless a tested migration path specifically says so.
Recovery fallback
If copied saves are ignored, restore the untouched original and confirm account ownership, folder level, and cloud synchronization before attempting another replacement. If the restored copy fails, put the untouched original back first. Then compare location, account/profile, cloud state, and the full directory structure before trying a different backup. The objective is reversible recovery, not repeated destructive experiments on the only copy.
