How do i extract files from *.dat packages ?

[Stavinsky]

I've searched around but must not ask
the 'good' question to the search engine.

So sorry if it was already asked and i didn't found it.

I'm actualy trying to mod some data, and playing
around with Submarines performance but
seems some of the informations
in u-boat's cfg files are not the one
used in the sim, so i'm curious if there
are some files in the *.dat files who could
help me do the change.

I've found the tool from Timetraveller to
extract tga kind of files from the dat packages,
and i was wondering if there was other tools
doing the same but for all the dat content ?

Thanks for any informations
