If you're copy / pasting them, then don't do that. Stop. Here's how it'll show up in the game:
.package files:
- When your custom content shows up in downloads, right click the file and select 'Cut'.
- Then go to the 'Mods' folder (Documents> Electronic Arts> The Sims 4> Mods).
- You'll see a file saying 'Resource.cfg' is already in it, but don't delete that! You need it for custom content to show up in your game.
- Then right click and select 'Paste', and your cc file is now in the game.
FOR .zip FILES:
- Right click on the zip file and select import. (My zip file looks like a purple book, a blue book and a green book tied together with a brown belt)
- After clicking import you'll get a mini screen saying 'Import to' and a list of places to import it. Import it too your desktop.
- Go to your desktop and there'll be a couple of .package files there.
- Right click the ones which you think are your cc and select 'cut' again.
- Paste them into the 'Mods' folder.
Hope this helped!
