Repacking Borderlands 3

[ShivShubh]

PAK files in Borderlands 3 are encrypted leaving no room for compression. So we simply need decrypted PAK files. I have made a program which deals with all that stuffs and gives you the decrypted PAK files.

You simply need to drag and drop the PAK file you want to decrypt on the program. Put the program in the same folder where all PAK files are. Download:

Updated... Fixed Game Crash. Please recreate pakchunk0-WindowsNoEditor_1_P.pak, pakchunk4-WindowsNoEditor.pak and pakchunk7-WindowsNoEditor.pak with this new version.

But before you use, things you need to know :
1) Put the program in the same folder where you have all the PAK files.
2) It creates the new decrypted PAK file in the same folder where your original file was and creates backup of the original file in "original" folder instead.
3) DO NOT USE this program on following files

pakchunk1-WindowsNoEditor_0_P.pak, pakchunk2-WindowsNoEditor_0_P.pak, pakchunk2-WindowsNoEditor.pak, pakchunk3-WindowsNoEditor_0_P.pak, pakchunk3-WindowsNoEditor.pak, pakchunk4-WindowsNoEditor_1_P.pak, pakchunk4-WindowsNoEditor_0_P.pak, pakchunk5-WindowsNoEditor_1_P.pak, pakchunk5-WindowsNoEditor_0_P.pak, pakchunk6-WindowsNoEditor_1_P.pak, pakchunk6-WindowsNoEditor_0_P.pak, pakchunk7-WindowsNoEditor_0_P.pak, pakchunk8-WindowsNoEditor_0_P.pak, pakchunk11-WindowsNoEditor_0_P.pak, pakchunk12optional-WindowsNoEditor.pak, pakchunk13-WindowsNoEditor.pak, pakchunk14-WindowsNoEditor.pak, pakchunk15-WindowsNoEditor.pak, pakchunk15-WindowsNoEditor_0_P.pak, pakchunk37-WindowsNoEditor.pak, pakchunk83-WindowsNoEditor_0_P.pak, pakchunk84-WindowsNoEditor_0_P.pak, pakchunk85-WindowsNoEditor.pak, pakchunk85-WindowsNoEditor_0_P.pak, pakchunk86-WindowsNoEditor.pak, pakchunk86-WindowsNoEditor_0_P.pak, pakchunk87-WindowsNoEditor.pak, pakchunk87-WindowsNoEditor_0_P.pak, pakchunk88-WindowsNoEditor.pak, pakchunk88-WindowsNoEditor_0_P.pak, pakchunk89-WindowsNoEditor.pak, pakchunk89-WindowsNoEditor_0_P.pak, pakchunk90-WindowsNoEditor.pak, pakchunk90-WindowsNoEditor_0_P.pak, pakchunk91-WindowsNoEditor.pak, pakchunk91-WindowsNoEditor_0_P.pak

So total files left = 82 FILES usable on this program. They are 31.2 GB in size just to be confirmed. Why not use the other files ?

pakchunk2-WindowsNoEditor* = Audio Files
pakchunk3-WindowsNoEditor* = English Language
pakchunk85-WindowsNoEditor* = French Language
pakchunk86-WindowsNoEditor* = Italian Language
pakchunk87-WindowsNoEditor* = German Language
pakchunk88-WindowsNoEditor* = Spanish Language
pakchunk89-WindowsNoEditor* = Japanese Language
pakchunk90-WindowsNoEditor* = Korean Language
pakchunk91-WindowsNoEditor* = Chinese Language
Other pak files = I chose to ignore. So separate these files accordingly and don't use them on the program.

Once you have decrypted PAK files, move the "original" folder somewhere out of the game folder because I think Unreal Engine can read any PAK file. Then test the game, it should work fine. I have tested and it worked fine in several testings.

Method to use for compression:-
for decrypted pak files = xprecomp+srep+lolz or any other
for audio files = srep+lolz or any other obviously, even srep only will do as it hardly gets compressed. I used Oodle kraken.
Installation is insanely fast. Took around 10 mins for ENG only installation

Please report if there is any problem !
