#UnrealEngine - UE4 GEMS - Unpack, modify & Pack the *.Pak files

In this video will go in details about how to use the UnrealPak commandline tool to unpack a game packed *.pak file, modify it, remove what might not be needed for the game in order to reduce the final game size, and then pack and compress the game data into a *.pak file again.

//Update:
As of today, most recent version is UE5.2 and everything in the video still doable, all commands still valid. You can still extract and repack a pak file at the same way.

I had a very specific use case for packing and unpacking, and I just wanted to pop in and say "thank you!!!" for this video. 👍

Bro, all I can say is, thank you a million times! I was trying to open the .pak file I have for days with other programs and nothing was working. I used 7zip and it just gave me a bunch of unknown files that I couldn't open. This video was awesome and you are awesome! Now I just have to figure out how to decrypt all the .uasset files I have and I'll be in business. Thanks again bro!!!

How about command extraction for ecnryption .Pak ??
i have the keys for this .pak, just dont know how to extract .pak with encryption. can u pls help ?

[ericbest]

Thanks so much - this is the only place on the internets that documents how to setup an OrderFile - which is the only way you can control the mount point in the pak.

Thanks so much for this. FYI, I had no trouble unpacking but I ran into issues with repacking because (I believe) my directory had spaces in it junk\Stalker 2 mods). Command prompt seemed to only get to in its attempt at packing. Once I moved my single file I needed to pack to the desktop and asked it to make a pak file on the desktop along with my "filesToPack.txt" file being on the desktop, everything went smoothly.

What to do if the game is encrypted and i also have the key???

[btlplumbing]

I think this tutorial is outdated
I did everything you did but I got an error when trying to execute, it was "The filename, directory name, or volume label syntax is incorrect."
