A program has already been created that can extract files from GTA 5's RPF files.

See here:
http://forum.xentax.com/viewtopic.php?f=10&t=10719&start=60 (scroll down to see the post by kornto.

The program has basic export functionality although I'm sure kornto will add more functionality as time goes on. By briefly looking at the code, it appears although R* have moved away from a purely hash based RPF (with no names table) and implemented a names table for GTA 5 - this means there will be no need to look for hashes for the majority of files.

As well as this, the encryption keys have also been located by multiple people, however due to copyright issues people are handing out the hashes of the keys instead (which can then be used to find the actual keys).

Another look at the code, it appears to include the use of XCompress.dll which would suggest compression is now entirely based on LZX (with no usage of deflate for non-resource based files) although I may be incorrect in this so please don't hold me to it.

I believe this sets the tone for a hopeful and prosperous time modding GTA V.

Many people are putting lots of time and effort on modding it. It doesn't surprise me one bit.

long files with numbers are the xbox 360 containers which are stored at the dlc location in 0000000000000 when you install disc 1. Just extract them with horizon or something lol.

Also anyone got the encryption key?

I'm just curious, could you replace the files using Horizon? Extract, modify and then replace?

Wow Cathering, Nice find it looks like there will be a bright future in the new GTA with modding, Hopefully it doesnt go to extreme like the GTA IV mods.

Well done!

you need to download the tool and get the key, put it in a binary file called key.dat in the same folder as the tool

The topic is still up, you just have to be registered. RPFTool hasn't been updated. I plan on making my own RPF tool soon :smile:
