I am sharing my mods folder with some folders setup.   

In the Mods folder there is an Overrides folder that contains the ContentPatch.package and ccmerged.package to help get store content to work properly.

In Packages you'll find the following folders. All of them are empty. No mods or custom content added, except the NoBuildSparkles.package and nointro.package files. You can find them in: The Sims 3\Mods\Packages\ModTheSims

I did add sub-folders in each of the main folders listed to help organize. You can rename them by clicking on the folder and select rename.

Blams - Add Store .package files to this folder.
CC - Add other custom content .package files
ModtheSims - is mods from that site.
Nraas - mods from that site.
TFM - Files from SimsAsylum.

Feel free to add files to these folders or delete them. You can also add your own sub-folders to the folders I've created to better organize your mods and custom content. :)

-- To create a folder, right click in the mods folder > Select New Folder and give it a name.

Please don't forget to back up your current mods folder to your desktop temporarily. I don't want you loosing any of your files.
