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.
Prepare the source PC
On the source system, identify the actual Resident Evil 4 save root: 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 expected file/folder pattern is win64_save directory records. Close the game, let the active launcher finish writing and synchronizing, then make a complete offline copy rather than transferring a file that may still be open.
Preserve storefront and profile identity
Documented 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. A transfer between two PCs is simplest when both systems use the same storefront/account/profile context. If the destination uses a different store or container, treat that as a migration problem rather than an ordinary restore.
Move the complete save boundary
Back up the complete win64_save directory for Steam, or the complete SaveData directory on macOS. Record the account that created the backup. Put the copied data on the destination only after confirming the destination save path. If the game creates a new empty save first, keep that new folder as another backup so you can compare structures and revert.
Handle cloud sync deliberately
Steam Cloud is documented for saves and most settings. Decide whether the local transferred copy or cloud copy should be authoritative before launching the game. If possible, preserve both. After the transferred save loads correctly, make a fresh in-game save and let the launcher synchronize normally.
Check compatibility before blaming the transfer
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. If the destination does not see the transferred progress, If copied saves are ignored, restore the untouched original and confirm account ownership, folder level, and cloud synchronization before attempting another replacement. Verify game edition/version, store, profile IDs, redirected folders, and mod/DLC dependencies before editing the save itself.
