Hi, the just released Dirt 4 from Codemasters uses nefs files.
I tried using codemasters_nefs.bms with no success.
error : can't read 1 bytes from offset a74527a9

Appreciate it if you can take a look.

Attached the file tested (first partial file as can't upload the whole file)

I guess that currently it's better to use offzip do to the job:

Code:

offzip -a -z -15 -Q -x -c 0x10000 str1.nefs OUTPUT_FOLDER

When I will have time and desire I will update the script

Hi, what should be the command for injecting the modded file back using packzip ?
Thank you.

offzip has a -r option that works just like quickbms but honestly I don't know if it will work in this particular situation with chunked content.
If you want to try it's just the SAME command-line you used for extraction plus the -r option just after "offzip.exe", remember to make a backup of your archive.
Obviously there is no support about this, it works or doesn't work.

No way to fix it.

what exactly does it mean "no way"?
Technically impossible? encrypted?

I managed to decode the nefs file and get the single files. So there must be a way to get them back into a NEFs file right?

hi,thanks aluigi
no any way to import big .nefs file?

Eh no, for 2 reasons: first it's usually necessary to dump the archive in a temporary file and then it uses chunked files.
I don't know if splitting the script in two parts and using the chunks without the MEMORY_FILE may change something but usually there are ever problems (even if quickbms has been tested to work with chunked files [memory_files too] in reimport mode but people report ever problems)... in short the main rule remains the same: if the game uses chunks you can't reimport the files.

Thanks, all files are extracted
But there is only one thing and there is a problem that was in the previous script.

Ah ok.
Yeah it happens also with other Codemasters games, probably they are duplicated files.

I get an error when unpacking a car package of the Lancia 037 and the Audi S1 (037.nefs / aqe.nefs).
It unpacks just the interior, not the rest of the stuff.
Let me know if you need a sample of these (each file weights 100 MBs).

Yes I need one of them
