CFS2 Hints'n'Tips

~S~ All
I have a couple of question's about Seeing other players aircraft in multiplayer and How to make it snow! from this sites CFS2 Hints'n'Tips.
First I can't find a file named combatfs.cfg within my CFS2 install which I need for the first tip listed above.
Second within my Weather folder I cannot find cloud.0 line. Only one of the files open with notepad the other two file's are garbled.
The question is, is how do I find and modify the above files?
