My sims folder doesn't look right, help!!

i recently downloaded the sims again and after booting it up and playing for a while i went to the game file to add some mods but when i looked i only have 6 folders:

"_installer

 Data

 Delta

 EP03

 Game

 Support"

i know i am supposed to have way more files than that plus a mods folder so i have no clue what to do in this situation, please help!
