[question]How to detect file compression

[ragnagard]

Hi there!

I am working on some files from MxO, wich extension is ltp.

In Hexviewer I saw that they contains only filenames on ASCII, each with a ltpX (where X is always the same ascii char) before it (like a delimiter) and data ater each one.

they appear to be only pyc (python compiled) files.

Filemon shows exe calling for:

/rootfolder/resource/python/xxxx.ltp/YYYY.pyc

so i really suspect that it may be a compressed file.

There is some program or tool to check for compression pattern?. Tried with "Trid" with not so much success.

MxO exe code shows use of zlib (dll) and deflate method but i cannot got a succesful decompression with python gzip/zlib handler.

One of those two files is only 500kb size, so i can upload if need & allowed, in case of needed to help me a bit.

PD: sorry if it doesnt match the right category, dunno where to put this exactly.
