Avacrest Search your computer for a Delta folder and jump there. (Open a File Explorer window, click This PC in the left panel, and enter the word in search field in the upper-right corner.) It should be inside the Sims 4's program files, and you can simply delete this folder and reinstall the game.
If you can't find Delta, look for the folder name of any pack you've ever installed. Here's a list:

Keep in mind that these searches can take a little while, so blank results for a couple minutes doesn't necessarily mean no results.
puzzlezaddict I deleted Delta, it doesn't change anything. I thought deleting it was supposed to clear out all the space the sims 4 was taking...
