If you’re looking for GTA 5 mods loader tools to properly mod Grand Theft Auto V PC, you’re in the right place, as this guide covers the latest versions of OpenRPF.asi and OpenIV.asi, explains the difference between them, and shows you how to install and use archive-based mods in GTA 5 Enhanced and Legacy.
Table of Contents
If you’re playing the newer GTA 5 Enhanced build or sticking with GTA V Legacy, using the correct ASI mods loader is essential for installing archive-based mods like vehicles, graphics upgrades, maps, and realism packs.
What Is a GTA 5 Mods Loader?
A GTA 5 mods loader is a small ASI plugin that allows the game to load modified game archives (.rpf files). By default, GTA V won’t read altered archives, which is where tools like OpenRPF.asi and OpenIV.asi come in.
They work alongside Script Hook V and an ASI Loader to safely enable mods while keeping the original game files intact.
OpenRPF.asi vs OpenIV.asi – What’s the Difference?
If you are wondering what the difference is between OpenRPF.asi and OpenIV.asi, here is how they both work in Grand Theft Auto V on PC for modders:
OpenRPF.asi (GTA 5 Enhanced)
- Designed for GTA 5 Enhanced
- Lightweight and modern archive loader
- Focused purely on enabling
.rpfmod loading - Ideal for newer GTA V builds and updated mod frameworks
If you’re running GTA 5 Enhanced, OpenRPF.asi is the recommended choice.
OpenIV.asi (GTA V Legacy)
- Used for GTA V Legacy
- Works with older game versions
- Integrates with OpenIV’s classic workflow
- Still widely supported by older mods
If you’re on GTA V Legacy, stick with OpenIV.asi for maximum compatibility.
How to Install GTA 5 Mods Loader (Step-by-Step)
Install Script Hook V
Script Hook V is required for all ASI mods.
- Download Script Hook V latest version
- Extract the files with 7zip
- Follow the Video Tutorial for correct installation
- Copy files into root
Add OpenRPF.asi or OpenIV.asi
- Copy OpenRPF.asi (Enhanced) or OpenIV.asi (Legacy)
- Paste it into your main GTA V folder (where
GTA5.exeis)
That’s it—the mods loader is now active.
How to Use Archive-Based Mods in GTA 5 PC
Archive-based mods modify .rpf files such as:
- Vehicles
- Weapons
- Maps
- Textures
- Sound packs
- Graphics mods
Recommended Method: Mods Folder
Never edit original game archives directly.
- Create a
modsfolder in your GTA V directory - Copy the original
.rpffile into themodsfolder - Install the mod into the copied archive
- Launch the game
The mods loader redirects GTA V to load files from the mods folder, keeping your base game clean and safe.
GTA 5 Enhanced vs Legacy – Which One Are You Running?
- Enhanced: Newer updates, better stability, use OpenRPF.asi
- Legacy: Older version, wider mod support, use OpenIV.asi
Using the wrong loader can cause crashes, infinite loading screens, or mods simply not working.
Is Modding GTA 5 Safe?
For single-player, yes—when done properly.
- Use a mods folder
- Keep backups
- Use the correct mods loader
- Don’t go online with mods enabled
Rockstar does not allow mods in GTA Online, so always remove or disable mods before going online.

Where do I install OpenRPF.asi and OpenIV.asi?
Both OpenRPF.asi and OpenIV.asi must be placed in the main GTA 5 installation folder, alongside GTA5.exe. An ASI loader such as Script Hook V is also required for these plugins to function.

OpenRPF.asi is intended for GTA 5 Enhanced and is not recommended for Legacy builds. Using the incorrect ASI plugin can lead to crashes, missing assets, or mods failing to load.
