Question [Solver] Build Size is big even after I deleted Resources Folder

Hi, I got a big asset in one of my project. But after getting a build of just my menu, the size of game folder was 1.2 GB's. So I deleted Resources folder and size went small like 80 mb's. But I needed to re-install that asset, after that I deleted Resources folder right away but even after I deleted it, Unity building the game like that folder still exist. I looked everywhere at the folders. There is no big resources file. So how my build gets big again? How can I fix it?

 

My problem wasn't about reducing size of my build, it was about it should have been small but still was big somehow. Anyway I opend a new project and copied the asset folder. Got a build and know my build size is small again. I don't know what went wrong with the previous project folder.

 

Just be aware some assets will place files into those folders to function properly. TextMesh Pro is a common one.
