RPFs and GTAV Mod Manager

go to the .RPF you want to edit, open in explorer, copy it, and paste it in RPF in your mods folder. Launch OpenIV, press ctrl+O (or click in the top left where it says open existing archive) and navigate to the RPF you pasted in the mods folder. edit that one with whichever mod that goes in there, and when done, open your mod manager (https://www.gta5-mods.com/tools/gtav-mod-manager) and it should appear as one of the mods. If not, then click "Import Modded RPF" and navigate to the RPF you edited (make sure it's not the one in the GTAV directory!) and voila! disable and enable it whenever you wish
