- GUI mode activated, remember that the tool works also from command-line
  where are available various options like folder scanning, filters and so on

- select the BMS script to use
- select the input archives/files to extract, type * or "" for whole folder and subfolders

- set output folder C:\Users\Dafuq\Downloads\quickbms\hd

  offset   filesize   filename
The archive is encrypted, select the number of the key to use or type yours:

- please insert the content for the variable KEY:

KEY: no key, encryption disabled
  ed9aa0f9 2683053906 00000000.dat

Error: incomplete input file 0: C:\Users\Dafuq\Downloads\quickbms\pakchunk0-WindowsClient.pak
       Can't read 64 bytes from offset ed9aa0f9.
       Anyway don't worry, it's possible that the BMS script has been written
       to exit in this way if it's reached the end of the archive so check it
       or contact its author or verify that all the files have been extracted.
       Please check the following coverage information to know if it's ok.

  coverage file 0     0%   236461     40809808   . offset ed9aa0f9

Last script line before the error or that produced the error:

Press ENTER or close the window to quit

this is a part from .PAK https://drive.google.com/open?id=1YQo_5LJFCzCV2W_v4IQ3nqt38YfWC5xn

If the algorithm is 1 (zlib, which wasn't visible in the copy&paste) then it's not a static key.

What do you mean by that? The key changes every time the game launches or something? (and yes it's zlib)

I simply meant that the text you pasted didn't have the "algorithm" field that I needed to be sure it was zlib, nothing else.
