I want to extract some pictures from the FIFA online3 and models, I tried some FIFA other versions of the script, but can not extract the file, can someone help me?

The "BIg4" is an obfuscated archive.
I remember to have already seen it in the past but I remember nothing else, the lack of a script on my website makes me think that I had no solution at that time.

Is there any way to extract them? For example, these files inside the picture

The "good" news is that only the TOC (the information about how/where are stored the files) is obfuscated while the content of the files is in clear-text and uncompressed.

In fact I was right, I already worked on this stuff in the past:
http://aluigi.org/bms/raw_ea_10fb_dumper.bms

There are references about the obfuscation in the header of the script but it's not true that it's "simply xored", that explains the reason of that script that is not a parser but it's just a work-around to find and decompress the compresse data.
And no, the script doesn't work on the data_7.big file you provided, I posted the link just for the record.

Where the script has been posted in origin:
viewtopic.php?t=1000

Oh, that is to say that this type of document can not be extracted at present? I use this BMS to try to open these files and find that there is no complete work

Yeah, currently no way except manual and semi-automatic ripping of the content (that doesn't seem compressed in the file you provided).
Anyway the script worked quite well with the other archives when I created it.

Thank you, my friend, I try to use this script to extract more of the other documents, found that there is a part can be extracted, but the role model and image map of a class of BIG files can not be extracted, do not know why, only to extract part of the UI file

Script 0.2:
http://aluigi.org/bms/raw_ea_10fb_dumper.bms

It's not a solution but now it's able to dump (well... to "rip") most of the data.
Use http://aluigi.org/bms/chunklzx.bms with the extracted chunkref/chunkzip/chunklzx files ("chu" extension).
