I need help locating the application data folder

Recently I have been updating my game with certain patches without a problem but when I'm required to place files within application data or appdata folder I find a problem. I have no folder by this name so when attempting to update roster and make changes to the config.cfg file is impossible I search and search but to no avail. Can anybody help with this? its very frustrating

I have no 2ksports folder or anything. The only foler that I have is streamapps/nba2k and thats it. I'm using Vista so I know my path to the certain location will be somewhat different but still.

C:\Users\[YOUR USER]\AppData\Roaming\2K Sports

Type this in your windows explorer (change [YOUR USER] for your user name )

Good Luck

Run %appdata%

thanks so much I don't know why I couldn't find it at first but that run appdata worked
