most of us dont expect people to be going through the files really...what? this has nothing to do with the files. I'm saying if anyone has another folder named nazi_zombie_town, this is going to extract straight into that and make a broken map. You can't have twp maps named nazi_zombie_town unless you rename one of the folders. And once you rename the folder you can no longer play multiplayer with anyone playing the normal foldername. It causes a mismatch, gg.
You can name your fastfiles whatever the hell you like but before you release your map to the world, take the time to give it a unique folder name.
