This download contains two small drag-and-drop tools (no GUI whatsoever) that allow you to easily extract and merge Sims 3 content.
These tools are made using code from:
- Sims 3 Mod Organizer by g0kur (source code)
- s3pi library by Peter L Jones
- TS3 Recompressor by J. M. Pescado (source code)
Requirements:
- Windows only at this time
- .NET Framework 4, which you likely already have
1. Sims 3 Easy Extractor (s3ee)
This tool extracts the contents of .Sims3Pack files and also extracts thumbnails from package files.
Features:
- Automatically renames extracted packages even if the .Sims3Pack file contains multiple files.
- Extracts a thumbnail of each extracted package.
- Automatically converts extracted DBPP packages to DBPF format, so you no longer need to process your Store content through Recompressor (s3rc).
- Extracts all CC from the extracted .sim file into a separate .package file so you can easily delete it if you don't need it.
- Extracts all strings from the extracted .world file into a separate .package file, as the game does not see strings merged with worlds.
- Automatically patches official Store content with the official patch (ContentPatch.package), provided that it is present in the tool's directory during the extraction process.
- Automatically fixes patterns exported from the CAP tool.
How to use:
To extract the contents of .Sims3Pack files:
- If you want to extract Store content, ensure ContentPatch.package is present in the tool's directory.
- Select your .Sims3Pack files, or select a folder (or multiple folders) containing them.
- Drag and drop the selected items onto s3ee.exe (you can drag them from another Explorer window).
- A command prompt window should appear where you can monitor the extraction process.
- The extracted files will be placed in the S3EasyExtractor folder in the tool's directory.
Where to install extracted files:
- Lots and households (lot_*.package and household_*.package files) → Documents\Electronic Arts\The Sims 3\Library
- Other .package files → Install like regular mods
- Sims (.sim files) → Documents\Electronic Arts\The Sims 3\SavedSims
- Worlds (.world files) → GameData\Shared\NonPackaged\Worlds in the game's install location
To extract thumbnails from packages:
- Select the packages you want to extract thumbnails from, or select a folder (or multiple folders) containing them.
- Drag and drop the selected items onto s3ee.exe.
- A command prompt window should appear where you can monitor the extraction process.
- The extracted thumbnails will be placed next to the files they were extracted from (make sure your File Explorer is set to sort files by name).
2. Sims 3 Easy Merger (s3em)
This tool merges packages as well as .Sims3Pack, .dbc and .ebc files using the merging function from g0kur's Sims 3 Mod Organizer.
Features:
- Automatically skips files that should not be merged (lots, sims, worlds, etc.).
- Automatically converts DBPP packages to DBPF format during the merge process.
- Automatically patches official Store content with the official patch (ContentPatch.package), provided that it is present in the tool's directory during the merge process.
- Automatically fixes patterns in .Sims3Pack files exported from the CAP tool.
How to use:
- If you want to merge Store .Sims3Pack, .ebc or encrypted .package files, ensure ContentPatch.package is present in the tool's directory.
- Select a folder (or multiple folders) containing the .package, .Sims3Pack, .dbc or .ebc files you want to merge.
- Drag and drop the selected folder(s) onto s3em.exe (you can drag them from another Explorer window).
- A command prompt window should appear where you can monitor the merge process.
- The merged files will be placed in the S3EasyMerger folder in the tool's directory.
Notes:
- This tool merges the contents of each dragged folder individually. If you want to merge all your folders together, put them in a single folder and drag that folder instead.
- The maximum size of each merged build is approximately 2 GB.
- If two files or subfolders conflict, the one with the name that comes first in alphabetical order will take precedence.
Tip:
I recommend placing s3em.exe with a copy of ContentPatch.package to your Mods folder (not in Packages or Overrides) and adding the lines below to your Resource.cfg file. This way, you won't have to move the merged files to your Mods folder manually each time. If you use CCMagic or S3MO, you will also need to add these lines to their settings.
