PatchMyPath for GTA V and RDR 2
PatchMyPath is a free and open source installation manager for Grand Theft Auto V and Red Dead Redemption 2. It allows you to quickly switch from existing game installs, so you can have separate folders for playing GTA Online/Red Dead Online and single player with mods. Is compatible with all game versions and stores (Rockstar Games Launcher, Steam and Epic Games Launcher). You can even use external tools like Unknown's Launcher Bypass or hooks like Dot's RedHook2!
