OpenIV4.1.1

OpenIV is the essential modding tool for Grand Theft Auto V (Legacy edition), GTA IV and Max Payne 3: it opens and edits the games' archive files (RPF), letting you browse, extract and replace textures, models, sounds and data files. Almost every asset replacement mod (cars, maps, graphics overhauls) is installed through OpenIV, often via its OIV package installer. Note: OpenIV does not properly support GTA V Enhanced — on Enhanced, use OpenRPF or RageOpenV instead (see their pages on GTVault).

⚠️ This tool is developed by the OpenIV team and distributed on the official openiv.com website. The download button redirects you there: it's the only reliable, up-to-date source.
