You delete the folders within

C:\Users\<USERNAME>\AppData\Local\Activision\CoDWaW\mods

Thanks i deleted the wrong files since i have steam version 2 lots of files i think in different locations

You close the program and reopen it. If the maps are still there afterwards then you aren't properly uninstalling your maps.

How do i go about properly uninstalling the maps other than deleting the files or uninstalling waw itself

having problems installing this via the ugx map manager whenver i install it it doesn't show up in the tools section or in the mod menu in cod waw,also how do you do i refresh my tools list i have unistalled all of my maps recently and the tools list isn't updating
