The Division SDF Archive Format

[SEB851]

they've upgraded the file format to a newer version for division 2, thats why rogue_sdf isn't working with the TD2 alpha.

while division 1 was sdf version 22, division 2 is sdf version 37.

idk if some other ubisoft game uses version 37, but the file header has changed significally and has more values (probably more block sizes).

it seems that they've splitted the data by language as well, at least there're now some "sdf-C-2000-en-US.sdfdata" files.

Any way extract this file ?

sure, but it'll be easier when the game is released and you have a running client.

they've probably encrypted/obfuscated the file, since its not that obvious anymore where the zlib data starts:

TD1:

Code: Select all

$ binwalk TD1/sdf.sdftoc 

DECIMAL       HEXADECIMAL     DESCRIPTION
--------------------------------------------------------------------------------
240053        0x3A9B5         Zlib compressed data, best compression

TD2:

Code: Select all

$ binwalk TD2/sdf.sdftoc 

DECIMAL       HEXADECIMAL     DESCRIPTION
--------------------------------------------------------------------------------

I have Alpha Test client files

[lunger]

I do know this much about the Alpha files:

• - 0x685F6 is the start of the compressed binary search tree for the alpha files

• - the only data after the compressed data is the ID block which is 0x30 bytes long

• - They added 5 new uint32 values to the header

• - The compression ratio is about 1% worse than Div1

• - the main game executable is roughly double in size

It only appears to be the same format. The file structure is the same, however the compressed data has changed and we have yet to identify how it has changed to update the extractor.

Any update on this, now as the beta has arrived?

[imXisheng]

Won't be any update until Lunger figures out how to do it.

Uses a different version of the file extension, that's why it's not working. To be expected to be honest.

Thank you, looking forward to your extractor. I'd love to just read whats all in there, not just the models.

Any update ?

Any update ?

I think something like this will wait till the 12-15th of March for the full release.

Well the archive format is unlikely to change until release, so...
