Help me D/L MODS & CC

Can you explain exactly what you're doing in detail? Did you enable mods and CC in the game options? 

hey, Yes the game mods and CC is all enabled on sims 4. i download the zipfile, copy the file to a mod file i made in Sims folder on my PC, but when i go to the game none of the mods are there.. thanks 

A few things could be the issue: 

1. In settings double check that game mods and script mods are enabled. 
2. Second, double check that you're putting the files in the correct mod-folder. You say you created a file, I assume you mean a folder? But you shouldn't have to create one, as the game should have generated it for you (it's just empty until you start putting things in). Make sure you unpack the mods in the right mods-folder. (Documents\Electronic Arts\The Sims 4\Mods)
3. Your mod folder cannot contain zip-files or rar-files, but it needs to be the extracted files. The files should end with "package". 
4. Some mods require a folder on its own to function properly. TMex's mods are like that. Follow the instructions when installing. 
5. If one of the mods is TMex BetterBuildBuy, and the mods you've put in are BB-items they won't show up until you enable it in the BB-view. You also have to turn BetterBuildBuy on for it to function properly. 
6. If you are still struggling use a source such as Curseforge for your mods, it will help you place the files in the correct folder for you.
