How to unzip the file, what type

[Goodwinsis]

I have a file in the archive. The contents are Packed. I can not find a program to unpack.
Please help!

Looking at that histogram, I'd rather think it's encrypted. Other than that, couldn't find anything about the magic "SFF" string at the beginning, extension ".bin" might be anything. Firmware maybe? There are some laptop models called SFF ("small form factor"). Also, "0G280183*2198170000*oiw" appears in the file, looks like some identication or a serial number.

I actually found some sff files, but they're different: https://github.com/msettles/rSFFread...r/inst/extdata :)

Also, cdm can't compress it and bitwise BWT makes it worse, so its not a bitcode, so its either high-quality AC or encrypted.

Maybe its "Structured Fax Format" and total command can read it through plugin in its plugins page :

based on the source, this one has different signature:

    SFF_HEADER.SFF_Id=0x66666653;

Where did you get that? It would help a lot to know.

If it is a game resource, chances are QuicBMS will extract it.
