Allrite, did a check and I got 2 files on the backup folders.
Both 1.4 and 1.5 version stock has these files.
\Terrain\Data\W158N022\W158N022.ZHF
\Terrain\Data\W158N022\W178N029.ZHF
I did check out them but they didn't have any meaningfull words innit.
Not with Hex editor atleast. 7zip failed also so I don't think they are packed
any normal way, if at all.
So, 1 folder up there's files like:
\Terrain\Data\TerrainData.BFD
\Terrain\Data\TerrainData.BFI
BFD search.
BFI search.
I guess so the 1gig file TerrainData.BFD holds the data.
and TerrainData.BFI might be some sorta index for it.
Check this out.
Im no real hacker so im just guessing here.
I suppose these are files (data library) for the terrain editor or somesuch
that Ubisoft used.
Question is, what app did they use?
Might be home brew apps.
