If you’ve ever used the Sims 4 Tray Importer, you’re going to love this tool for The Sims 3!

It was created to make life easier for players who use custom content (CC) and want to keep everything organized or to share fully CC-included Sims in a quick and practical way!

(The first version was ready in October from last year and I'm publishing it now lol)


What does this tool do?

✔ Automatically copies all .package/.sims3pack custom content used by a SimHousehold or Lot into a specific folder.

✔ Includes an option to pack the folder for easier sharing or storage.

✔ Works with both individual Sims and full Households (or Lots).

✔ Can also help you identify which .package files you no longer want in your game.



Features:

✔ It copies the folder structure from your Downloads/Mods folder, including only the necessary files, keeping the CCs organized.

✔ Compatible with three languages: Portuguese, English, and Spanish.
(If your system language is not one of these, the tool will default to English.)

✔ Clickable thumbnails to quickly open the thumbnail file location.

P.s.: If you’d like your language included, just send me all the tool’s text already translated, and I’ll add it.


Credits and Thanks

Special thanks to Peter Jones for S3PI (package reading library), to Kitilith for the idea and basis of their Find Merged CC tool used in this project (credits will be included with the readme file as requested on their GitHub) and to Tashiketh for CUSTARD Sims3Pack Cleaner (sims3pack reading code).

I’d also like to thank Ash (cowplantcartel) for testing this tool in every build. 😅
