I did do some searching on the Wolf:ET pages but found no answer to this question.
With your help I was able to install Wolfenstien: Enemy territory just fine but I can not figure out how to install the update.
Here are the update files is gives me:

I looked in my Wolf:Et directory but there were no applicable files to replace.
I read the info.text that came with them but there was no help in there either.
So, is there someting I do with these files in the Konsole? Any help would be appreciated.
