Can't update

The Sims 4 folder in my Documents is only 2.33 GB. My mods folder is 590 mb. It's definitely not my mods causing the lack of space.

In C: Program Files, the Electronic Arts folder is 1.25 GB. It has the EA desktop. Why is that using so much space?!

The Sims 4 and all its expansion info are saved under C: Program Files (x86)\Common Files\EAInstaller\The Sims 4 and is 79.5 mb.

I think the actual game files are under C: Program Files (x86)\Origin Games\The Sims 4 and are in total 66.8 GB.

My saves folder is 821 mb in total. Tray is 855 mb.

I do have an external drive with 900 GB that has all my extra save files and mods I would like to use, but can't due to no room on my computer. It also has all my documents, books, pictures, videos, etc., since my computer is running out of space. I moved everything there and deleted it from my C hard drive.

On C drive I am using 201 GB and have 20.5 GB free after cleaning everything I know to clean. I can finish downloading the game and play it, but I don't think I can buy and download any more packs or kits. My C space is in the red.

I did the disc cleanup on my computer. Emptied my cache and browser info.

My Documents 7.64 GB

Downloads 0 mb

Music 10.5 mb

Pictures 0 mb

Video 0 mb

But what the heck is taking up so much room?! How do I find out? I have a couple of programs like Microsoft office, McAffee, Sims 4 Studio, Sims 4 Mod Manager, Curseforge, a couple other little Sims programs, a HTML editor, Gimp 2, a couple browsers and that's about it.

I know I need a new computer but can't really afford one. :\
