I'm afraid that the only thing that could be done is to write custom tool for unpacking and packing in C++, Python etc. This quickbms script you provided is not that hard to rewrite except this ALZ compression routine which may be problematic. You could probably search through quickbms source to see...

Ok, I think I get it now. So it is not really an technical issue, rather work orginizing issue. :D So my advice would be to create separate folders for each category, then sort all clips in those folders and then use some auto renamer tool like this one https://www.advancedrenamer.com/ I don't think...

Can you describe how do you do it manually now?
And can you upload some sample files before extraction? (no more than 100 MB if possible)

Nice stats

Maybe it's because you are using some old version of Nifskope.
Both samples extracts just fine with QuickBMS and both NIF files
loads fine in NifSkope 2.0. See the screenshots below:

Only by writing custom tool.

Could you please upload some samples? The best option would be to have some samples that work and few other samples that don't work in separate directories. but I'm definitely not afraid to try that and learn how to do it- in fact I'm more than willing to learn processes like that. You can learn her...

It seems that there is decoder in vgmstream for this format
https://github.com/vgmstream/vgmstream/ ... _decoder.c

So maybe you should try foobar + vgmstream plugin combination.

Yes, you can use Foobar + vgmstream plugin for that

same with quickbms (error in src\file.c line 557: fdnum_open() Error: No such file or directory) To know how to use quickbms, you should read documentation here http://aluigi.zenhax.com/papers/quickbms.txt From the error description, it seems that you haven't provided required archive (or index fil...

What game these files come from?
And why do you think they are ogg files?

I need a game-specific script(?) to make extraction possible You probably mean QuickBMS script. Here you can download it http://aluigi.zenhax.com/quickbms.htm and here you can read documentation on how to use it http://aluigi.zenhax.com/papers/quickbms.txt If you want to learn more advanced stuff, ...

I have answered by Facebook, but I'll leave here solution for others:

You need to download TexConv https://github.com/Microsoft/DirectXTex/wiki/Texconv
and put it in Rawtex's directory.

I was able to extract image data using raw texture cooker https://i.imgur.com/4J1aX4R.png
It seems that MFNT chunk contains r1_unom graphics.
