M2 File Format

[amaru]

Hey everybody.
I checked throughly wiki at M2/WotLK - WoWDev regarding M2 file format. I've also wrote a tool that was supposed to read/write m2 files https://github.com/Dramacydal/M2Lib
Everything is smooth and adequate except one thing:
I have a model of ~1.5 Mb but when I read and then write model I produce a file of 250kb. One may think that it is a bug in my library but maximum offset that I get while parsing M2 header (and it nested structures) is also around ~250k.
I'm curious where ~85% of all data gone
Brief looking at client disassembly I also haven't noticed any data reading after parsing of header

Maybe there is anyone who is familiar with this sort of thing?
Thanks

Hi.
I am a bit familiar with the M2 format. I have myself too recently created a lib, mine is in Java : https://github.com/Koward/jM2lib .
If you are looking for missing data, why don't you re-read your output file with your lib ? Try with a simple model. Then compare the data.
Do you have a way to visualize data ? Try to print (or whatever allows you to check if every is right) the bones.
BTW, there are more specialized websites if you want to specifically learn about the format itself.

Hi spik96.
Yes I tried to re-read what I had written, i got identical output. Can you tell please any site that is related to this subject that you know?
