Where wow is downloaded

[damnchy]

Hi guys I have a problem small SSD here downloaded minimal client had 80 GB left space now I have zero and still continue to download

I have the feeling every time click the icon from minimal client to start playing it is like the first initiation and always loads very slowly from the beginning like every time, it makes its own new directory somewhere and starts downloading again even downloads new files on places I have been already like dungeons battlegrounds etc.

 how can I locate these big files delete all of them from the minimal client and just download 1 full 50, 60, or 70 GB game ???
as at the moment I have no folder or files on my computer but got 80 GB missing from my space.
