The Amazing Spider Man 2 (2014) has a file called Streams2.dat, it's the largest file in the entire game (2,323,030,372 bytes / 2.16GB) and I don't know how to compress it efficiently.

I threw it into RAZOR12911's scanner and this was the result:



There's zlib streams so I decided to use XTool Zlib, but that didn't do anything:

Compressing 2 files, 2,323,030,372 bytes
  Compressing Data\
  Compressing Data\Streams2.dat
Compressed 2 files, 2,323,030,372 => 2,323,031,492 bytes. Ratio 100.00%
Compression time: cpu 2.23 sec/real 72.99 sec = 3%. Speed 31.83 mB/s
All OK

ZTool zlib was the same:

Compressing 2 files, 2,323,030,372 bytes
  Compressing Data\
  Compressing Data\Streams2.dat
Compressed 2 files, 2,323,030,372 => 2,323,035,496 bytes. Ratio 100.00%
Compression time: cpu 2.09 sec/real 50.60 sec = 4%. Speed 45.91 mB/s
All OK

PZLib also had a simlar result at a 100% ratio.

Is there something I'm missing here? There's also lots of WAV streams detected, but I don't know how to focus on them. I tried MSC, but that only found WAV streams of an unknown file type, and did nothing.

I don't think the file could be encrypted because the streams were detected.

If anyone has any tips, they'd be greatly appreciated.

XTool + MSC?

I tried adding the c128 command into XTool and it slowed it right down, taking ages to go barely 0.1%.

@Masaqurde... use "srep+lolz" method it'll worth the time I hope...

Also have you tried the x86 version?

I always use x86 version of XTool. I've never used x64 version. I just used srep and lolz and it came out at 1.9GB which is good enough for me. Very hard file to process.

Thank you all for the help.

It's defintely not Unity, there's no Unity binaries or File Structure present for it to be unity.
