OpenIV is a multi-purpose editor and archive manager for RAGE engine-based games such as GTA V, GTA IV/EFLC and Max Payne 3, developed by OpenIV Team. Development of this tool began shortly after the Xbox 360 release of GTA IV. The first public version was released on December 28, 2008. Since version 1.0 OpenIV also supports another game made by Rockstar Games – Max Payne 3. Since version 2.0 OpenIV became one of the world’s first tools to work with GTA V‘s new file formats. OpenIV won the Best Tool award in GTAForums Annual Awards 2016.
It is an essential modding tool for GTA V as most of the mods, patches, mega packs require Open IV in order to install them. OpenIV is required for all the .oiv files (package installer).

What’s new in OpenIV 2.9.2:
First time since 2015, we have updated OpenIV.ASI – our plugin, which provides mods support for Grand Theft Auto V. The latest version of GTA V has some non-critical changes in the code, which affected by OpenIV.ASI, and we made similar changes in our code. Without those changes in OpenIV.ASI, your game had crash during loading screen in some very specific scenario, only when you have Simplified Chinese language selected in game. Use ASI Manager to update OpenIV.ASI in your game folder.
• We fixed an issue where sometimes OpenIV crashes while renaming folders inside archives.
• We fixed an issue where import of texture image with 2×2 sizes was impossible due to infinite loading.
• We fixed an issue where files was not shown in OpenIV after they was drag-and-dropped in game folder using Windows File Explorer.
