What is OpenIV ? How to modify GTA 5 with OPEN IV | Complete guide to Modify GTA 5

   1 – Download and install OpenIV. Configure it to work with your copy of GTAV.
   2 – Navigate to ASI Manager using menu “Tools” > “ASI Manager” or “ASI Manager” button on tool bar.

Through ASI Manager, you can install, update or remove ASI Loader and OpenIV ASI plugins.

3 – Install ASI Loader and OpenIV.ASI

4 – Open your GTA V folder in File Explorer; you can do it fast in OpenIV

5 – In root of your GTA V folder create new folder and name if “mods” (lower case)

6 – Now you have to copy RPF archives into “mods” folder. For example, if you want to modify “Grand Theft Auto V\update\update.rpf” you need to copy it like “Grand Theft Auto V\mods\update\update.rpf”.

The following table is explain how you need to copy archives to mods folder. The path to RPF archive in “mods” folder must be the same as in real GTA Vfolder, here is some examples:

Grand Theft Auto V – Original archive path	Path in “mods” folder
GTAV\update\update.rpf	GTAV\mods\update\update.rpf
GTAV\common.rpf	GTAV\mods\common.rpf
GTAV\x64\audio\sfx\SCRIPT.rpf	GTAV\mods\x64\audio\sfx\SCRIPT.rpf
GTAV\update\x64\dlcpacks\mpheist\dlc.rpf	GTAV\mods\update\x64\dlcpacks\mpheist\dlc.rpf
GTAV\x64e.rpf	GTAV\mods\x64e.rpf

7 – From this point if you want to install mod or edit some file you need to do it in archive from “mods” folder.

Now all your mods will be in separated folder, and original files will stay not modified.
If you want to switch back to original files just go to ASI Manager and remove OpenIV.ASI. In addition, you can remove ASI Loader to disable all ASI plugins that you have installed.
You can use ASI Manager any time to switch between mods and original game. You no need to remove “mods” folder every time.
