[@malarkeman]

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!!!

[@asrio]

hey, did you figure out how to decrypt the .uasset files?

[@malarkeman]

@@asrio Yes and No. I used Fmodel and Umodel but I was only able to see some image files and even some of the models. My purpose was to access the sound and music files, but neither of these programs were able to access them. I mean, I saw the files, but there was no way to open them and actually listen to them. So, I gave up and moved on to other projects.

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.

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 ?

[@cnnhean]

were you able to solve it ?

[@troypinkerton9876]

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 (C:\Users\xxxxx\Desktop\Temp junk\Stalker 2 mods). Command prompt seemed to only get to "C:\Users\xxxxx\Desktop\Temp" 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.

Thank you, nice overview :) ..though for this case, there is a "Exclude Editor Content" project setting that can be enabled in the editor. :)

Yes know about that option, give it a shot :P it still leave editor folder and editor content in the build ^_^ I would say suspecting that checkbox, was the main driving force behind unpacking the pak files to see what actually left in there.

Is there a way to fix this or it is just the way it is as no way to get the project back?

not because unpacking will give you a *.uasset, you can copy it to your unreal project and expect it to open normally :D Not to mention, this is not allowed, and sort of "piracy", the purpose of unpacking the pak files is more about doing that for your own game pak files, not in other commercial games pak files ;)
