Hei guys!

I don't have much skills regarding PC storage so I'm wondering one thing. I'm playing this game on PC (through BlueStacks App) because I have old phone. Anyway... A lot of times before going PvP, game is downloading something, I don't know what. But I'm guessing it's not that small size, because it takes a lot of storage on my computer. So I wonder how can I get rid of those downloaded files without losing any data in game or/ how can I get back my storage on computer?

Thank you for your help!
