How do i manage separate save files in gta v?

The only verified evidence supplied refers to Grand Theft Auto Online, the multiplayer component of Grand Theft Auto V. It describes release dates, platforms, setting, and gameplay features, but it does not mention any details about managing separate save files for the single‑player version or the online component. Consequently, there is no documented information in the supplied evidence that can answer the question about managing separate save files in GTA V.
