Unfinished Update took all of my space

Hi! I attempted to update the Sims 4 today. I spent the day deleting and updating cc. The update said it'd take 8gbs  so i started the update. (for refrence im doing a catalog of all my mods working and non working so I can get ready to switch to Pc my game is about 5 years old and i havent had to do the 50/50 method or delete my folders YET and I'd like to keep it that way. ) My update paused becuase I needed about 38 more mb. (not freaking out about space I've played with less and know the update just kind of reserves the space). So i went to delete something usless but noted that the partially done update took ALL of my 8gb of storage without finishing. Ive tried app data and program data and all of that but i cant find any files that are too big. my game is heavily modden and jailbroken so all of my files range from 1mb-300mb nothing too crazy and nothing extremely large to take 8gb. does anyone know where the update temp files are stored?
