DDS files?

Where do i put DDS files?
I cant find it

You either delete the .DDS files once you're done using them to make a skin or put them in the main data folder. I forgot which; I honestly have not touched OG in a long time.

If you're wondering how to use them as a skin, you have to use a hex editor and edit a file like dinos_tendaguru.tml. You can check out Godzillaman's skinning tutorial if you want info on that.
