Hello aluigi, thank you for your work.

I was wondering if you could help me extract PAK files from a game called Conan Exiles. It's an Unreal Engine 4 game. When I tried your QuickBMS I get this:

It actually extracted 1 file but only 1 file from it.

I saw someone had a similar issue and you were able to fix it. I would greatly appreciate it.

Here is the PAK

here is the game EXE

Thank you in advanced.

@blueex77
Script 0.4.17 but keep in mind that it's just a work-around because this pak has an additional field (32bit 0) not covered by the format

No sense to upload archive. Key is contained in main executable.

@GoodConduct
it's an aes encryption specific for these uasset files:
http://aluigi.org/bms/figureheaders.bms

I don't know if all the files of any type are encrypted so the script automatically gives the guessed extension to the file, the uasset extension has been implemented in quickbms 0.8.3 or 0.8.4 just in case you are using an older version.
