Monster Hunter Rise’s Steam save set is more than one numbered slot. The `win64_save` directory also contains shared/system data, so restoring one file in isolation can create mismatched revisions. For a dependable backup, archive the entire directory and keep the Steam account context. Microsoft Store/Xbox uses WGS, which is a separate storage model and should not be converted by renaming `.bin` files.
Prepare the source PC
On the source system, identify the actual Monster Hunter Rise save root: Windows: Steam: <Steam-folder>userdata<user-id>1446780remotewin64_save
Microsoft Store: %LOCALAPPDATA%PackagesF024294D.50755C2F12831_8fty0by30jknySystemAppDatawgs<user-id> | Linux / Steam Play: Steam Play: <SteamLibrary-folder>/steamapps/compatdata/1446780/pfx/. The expected file/folder pattern is data00-1.bin
data001Slot.bin
data002Slot.bin
data003Slot.bin. 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, Microsoft Store / Xbox app. Steam and Microsoft Store use different containers. Steam remote storage exposes win64_save paths; WGS should be preserved and handled separately. 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
Copy the entire 1446780 remote/win64_save folder, not only one numbered slot. Keep data00-1.bin and all active slot files together. 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 and Xbox Cloud are documented. Steam remote-storage downloads may prefix the folder path into downloaded filenames, so restoration should preserve the expected win64_save layout. 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
Steam PC save records live in win64_save. data00-1.bin is shared/system data while numbered Slot files represent save slots. Microsoft Store/Xbox uses WGS instead of the same file layout. Compatibility note: Slot files and shared/system data belong to one profile context. Mixing revisions can create a state the game did not produce. If the destination does not see the transferred progress, If the game reports no save data, preserve the local folder first and compare it with Steam remote storage. Do not overwrite every local file with one isolated cloud slot. Verify game edition/version, store, profile IDs, redirected folders, and mod/DLC dependencies before editing the save itself.
Verification context: Steam and Microsoft Store paths were reviewed against current PCGamingWiki coverage. Current SteamDB and Steam community recovery documentation were used to cross-check the win64_save file set.
