Finally, after almost a year and a half of waiting, the gaming community waited for the moment when it became possible to create and install custom modifications on GTA 5. Some of them are installed by simply adding files to the root folder of the game, but for a huge number of modifications, you need to change the files in the game archives. which cannot be done without using special programs. One of these programs, and perhaps the most convenient, is Open IV. This super useful tool will allow you to easily edit the hidden archives of the game, add and modify files in them, and all you need to do to get all these features at your disposal is to download Open IV. Apart from that, Open IV is a very convenient and probably necessary tool for developing mods.

For example, let's say we want to set a texture to replace the default weapon model. How do we do this without OpenIV? Of course, no way, but with the help of Open 4 we can do it in two clicks. With the same success, you can easily add new files and folders to the game archives, which provides the widest scope for modding and allows you to do almost anything with the game. It's safe to say that Open 4 is an absolutely essential program for any fan of GTA 5 modifications.

We suggest you download the latest version of Open 4 from our website.

How to use OpenIV

Click on the OpenIV icon to start the program, select GTA 5, then your system and wait until the download is complete.

You have entered the program menu. Everything here looks like a standard explorer, allowing you to see all files, archives and folders in the root directory of GTA 5. You can move freely, open any archive, however, in order to change or rebuild archives, as well as add or delete files, you need to enable the mode editing as shown in the screenshot.

Next, follow the instructions for installing your modifications. Most often, you just need to replace the texture or script files, much less often you have to add new folders and files to the game archives. In any case, the first rule of using OpenIV is to make backups of all replaced files. In edit mode, the program automatically saves all the changes you made, so if you do something wrong and there are no source files at hand, then GTA 5 will have to be reinstalled.

That's all, now you can easily install any modification, for this you only need to use the excellent Open 4 program.
