#UnrealEngine 

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!!!

Thank you for this! I was searching a good explanation for a while and only yours works for me ;)

I am attempting to make my first mod, this is the only source of info for getting into pak files. Thank you!

Is nobody gonna mention the mouse cursor wiggle waggle

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.

You are the Prince of Persia of the Unreal Engine best tutorial videos..

Great thanks! I was fumbling to get my dir in .pak right and searched the whole internet, and your tutorial is the best and the most clear!

Very informative and to the point. Learned a couple tricks from this. Thanks.

Days.... DAYS MY DUDE. I've been on the hunt for this for days and THIS is the answer! Thank you so much! I'd hug you if I could!

You are an F'n G muh dude! Been trying to export mesh's out of a pak file for a minute, found the unreal version in the header, installed that version, got the pak.exe and extracted like you showed. I just got my BP's, textures, and all back!!! it was UE4.12! I couldn't remember which one or get the files till now, THANK YOU!!!

Failed to find requested encryption key 00000000000000000000000000000000 extract how to fix?

Welcome bro! It worked fine! Welcome so much!!

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

How about unpacking .pak files from other games?

holy shit ,i press enter noting happens .....then BOOM a lot of files start extracting :) still working UE5 :) beast

I'm trying to repack Final Fantasy 7 Remake pak files using this program so I can mod the game, but it's not working :( The game crashes when I try to run it

Used this to make a mod for Ready Or Not. I am so luck, I kept doing it wrong, following your tutorial incorrectly. I want to apply this to my own games now

Now to figure out how to edit uasset files. Seems there are almost 0 programs online that can do this. I just wanna edit some mods lol. Thanks for the vid

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."

I Subscribed and Like for this vid..gg bro

Nice video! But I have another problem. I would extract files from the game "Bramble - The Mountain King". But the problem is the files are in an .ucas archive. Can you make a tutorial how to extract files from this? Thank you :)

Hey, how do you do this if the pak has an AES key? Where do you put it so it can unlock the files?

very late on this, but is it possible to pull out files from uasset file themselves? im dealing with a game that doesnt store the files in a pak, but rather than just uassets that are inside the content folder of my game with no pak at all

"Wow that's a lot" I spent a while just unpacking the Halo MCC pak file so I could modify a few god damn sound files.

Hi, I got to the step of creating the project files but then the command prompt would show a window saying "unsupported 16 bit application" was wondering if the new Unreal Engine 5.0 causes that, and if so is there a way to work around it? Thanks

This vid helps a lot! Thanks!

i see "error unable to access .pak file" can you help me please ?

THANKS IT WORKING ON STEAM GAME WHO USE THIS ENGINE

You Forgot to mention that the "\*" after engine and game is needed to specify that the directory is a folder to be packed, not and individual file

At what point I need to enter the encryption key? I have the encrypton key.

could this be used for changing the Radio station music in any of the games in gta trilogy definitive edition

LogPakFile: Display: Using command line for crypto configuration LogPakFile: Error: Unable to open pak file "C:\Users\pvpmc\AppData\Local\Mojang\products\dungeons\dungeons\Dungeons\Content\Paks\pakchunk0-WindowsNoEditor.pak". LogPakFile: Display: Unreal pak executed in 0.000762 seconds Please help, tried with UE 4.25.3

Thank you bro this is so helpful

tried this and it just gave me fatal errors saying my file was 'different than the expected one' and to verify the files.

Can we compress all the pak files into one with this and save space on the HDD

Is it safe to delete engine/shaders/standalonerender/*? checked test game it ran fine but anyway what`s the purpose of these files? Are there similar junk files in Unity builds to delete? Also binaries/thirdparty/ICU was OK to delete in my case.

how is the command for files that need the aes key? where would you add?

How do you know that a particular game was developed using a particular version of the Unereal Engine? I had a case where only the version the game is on was able to package modifications so that the game would load it

could you make a video about how to reverse engineer and edit .cpp script files and rebuild it for unreal games ?

I was tryna to make .sig file out of my modded .pak but then the .pak size turn into 0kb. Any clue?

how do i use the AES Key in Command Prompt

This tutorial can be used to change character in UE4 games?

And if it was encrypted? How to decrypt? I lost the original project file

no idea if you still here but i always get error when pressing "enter at the 2:50 part

thanks man!!

Thank you Sooo Much for this video

It would be nice if it were simpler like WinRar. I have 26 .pak files and I don't know which one contains the game's soundtracks. If I were to do it one by one, it would take a long time.

this is to this day the best video for explaining it

would of been easy if you just write the steeps down in the description since you dont have a mic?

Hi, how can I encrypt the pak file with AES-key? I have a key but I dont know how can I add this key with cmd.

Thanks for the video. Is there a way to just get ahold of the unpack.exe, and unpack the files, edit them, repack, and install the mod?

Bro not working for me I m using unreal engine 5 4 3 log file error plz help me

When I do it, it says "fatal error". It says: Failed to find requested encryption key 000(...)

How I get and download the UnrealPak.exe file application?

Just awesome ! i didnt know that this is possible. Is there a way to reuse the exported assets ? i see that behind every ".usasset" file is a ".uexp" file is there a way to bind that files together that i can re use the files ?

This 70s porn music got me shook

any answer if when I -Extract and want to -Create but my extractedData folder doesn't have folders and just a single sqlite file? do I simply put the filepath to the sqlite?

LogWindows: Error: Unable to create backend graph using the default graph settings (DerivedDataBackendGraph) ini=../../../Engine/Programs/UnrealPak/Saved/Config/Windows/Engine.ini.

What if the pak file is encrypted? What if it's my own project? I just want to verify that something is indeed being packaged.

Quick Note: dragging files into command prompt did not work for me, but right clicking the file and picking Copy as Path and then right clicking inside the Command Prompt did the trick.

Thanks a lot!

The filename, directory name, or volume label syntax is incorrect. ???????????????????????

This process only worked for me once and the second time I tried with another .pak file it sent me an error, that the .pak file was not found in the path, but the file was there but it no longer had the same weight and I don't know why it came back To put the .pak file with a weight of 1g for example, I opened cmd and towards the process I pressed enter and I got an error of the path the pak file is not there but as I said it was there but from weighing 1gb it went to 345kb I don't know why it will be.

I followed your steps and it works perfectly, but what if I have to order the contents in the pak file? What do you do to the that because some games need the pak file contents in a certain order for it to work

is it possible to do the same thing for this typ of file .fbmod (frosty project) ?

Got An Issue When i Unpacked my game and try to open the project the uassets get corrupted? How do i fix this?

Awesome!! very usefull

Well it didn't seem to work for me, idk if im doing it wrong but im trying to do it on a game from steam that won't let me enter the PAK file

game not run after the replacement

Cursor is op 😳

after i extracted it in the editor i only get folders and and the project file and thats it no models nor textures but they are there in file explorer

Please.. any solution for" The filename, directory name, or volume label syntax is incorrect. ' dragged and typed exactly what you did.. I have UE 4.27 .. is it strictly version specific?

not working

i followed the procedure just to edit .manifest files, but i can't find them or maybe the cmd doesn't extract it. Can someone help please

it keeps saying The filename, directory name, or volume label syntax is incorrect.

what do I do if the files are encrypted but I have the key, how do I unpack them with the key, when I try -Extract it just says couldn't find key and errors out, but when i try to add the key as a argument it says wrong syntax. please respond asap

please, how to create .sig file from .pak file?

Can you get maps out of .pak extractions? I have a demo game from a client. The last person she worked with only gave her the demo of the game and it's not editable. We have all the assets but would love to be able to get her demo back to being editable. Does this make sence?

Hi! Help me, please, to understand what’s the matter of my simple pak unpacking and packing back totally without any changes leads to the error - can’t open descriptor file?

useful video, thanks. assalamu alaykum.

I tried this multiple times, did everything you did here but i keep getting LogWindows error and the new file has no data. Does this method still work?

It does not work, what am i doing wrong. I drag the pak space unrealpak.exe space -extract space folder enter

Hi! When I try to pak them back up, I get an error which says that some filenames are the same. I dont understand why, because I checked most of the files and there are no copies of one another. Can you help me, please?

What about UE5 ? This approch does not work...

Hello, does this still work in Unreal Engine 5.2? i doubt it, because when i do this it just gives me a couple .wem files.
