I was recently trying to figure out how to convert Sims 3 Store Content to the Sims 4. I have finally found an easy way to do so. This is the second conversion tutorial that I have done, here you can find the Object Conversion Tutorial. We will be referencing that tutorial later.
This tutorial is for TS3 store content Objects, not CAS items.
As a reminder, before converting any items from the Sims 3 be sure to have the original creators permission.
For this tutorial you are going to need the following programs:
- The Sims 3
- Delphy’s Sims3Pack Multi Extractor (*Registration Required)
- S3RC
- TSR Workshop
- Sims4Studio (*Registration Required)
You must have The Sims 3 installed on your computer, you may also install any expansions or stuff packs you have, but the base game is required.
Optional Programs:
The following programs are not needed but will come in handy later in this tutorial.
Be sure to download and install these programs, if you have any questions on installing please ask.
I will be walking you through the conversion steps in sections, I will refer to other sections so please follow this guide step by step.
Sections are as follows:
- Section One – Installing S3RC & Delphy’s Sims3Pack Multi Extractor
- Section Two – Converting Sims3Pack files into .package files
- Section Three – How to re-compress .packages with S3RC
- Section Four – Checking .packages with S3PE (Optional)
- Section Five – Opening final .package with TSR Workshop
- Section Six – Follow Object Conversion Tutorial
In this section I will be walking you through the steps of installing the programs you will need for part of the tutorial.I will not be teaching you how to install Sims4Studio or TSR Workshop. If you have any questions on installing those programs feel free to ask.So, lets get started.





In this section I will be showing you how to convert Sims3Pack files into .package files with Delphy’s Sims3Pack Multi Extractor tool. The reason that we change the file type is to make it easier to convert to The Sims 4.Important: Do NOT download more than one Sims3Pack at a time, or you will end up with a ton of .package files you will have to sort through.Make sure you have installed Delphy’s Sims3Pack Multi Extractor and it is located on your desktop.So, lets get started.






In this section I will be teaching you how to re-compress a .package file with S3RC so that It will be formatted correctly to open with TSR Workshop.So, lets get started.


This section is Optional! This section is meant for those of you that have multiple Sims 3 .package files, meaning you have converted an entire set of items.In this section I will teach you how to open you Sims 3 .package files with S3PE to locate the thumbnail of each of you .package files so you can distinguish which .package is which item.If you do not have multiple .package files you can skip to SECTION FIVE.So, Lets get Started.


In this section I will teach you how to open you final Sims 3 .Package file with TSR Workshop.So, lets get started.
