I had to extract a .pak folder using winzip to change a setting to get the changing time of day on my server. Then im suppose to take all the files in that folder, and change them back to .pak and overbite the other .pak with the new one.
So all i need to know is how to go from .zip to .pak.
Open the pak file with pakscape. Find the file and export it. Do your work. Repack the file using pakscape.......... do not over write the original game files. Make a new pk3 file....save as.... zzzzzzzz_mymods.pk3. Slip this file into the games main or where ever the original pak file came from.
