Transferring Sims 3 Saves Between Laptops: Step-by-Step

Yes, moving The Sims 3 saves is straightforward. The save folder is portable.

Locate Source Saves (Old Laptop)

• Windows: Documents\Electronic Arts\The Sims 3\Saves\
• Mac: ~/Documents/Electronic Arts/The Sims 3/Saves/
• Steam Deck / Linux (Proton): ~/steamapps/compatdata/47890/pfx/drive_c/users/steamuser/Documents/Electronic Arts/The Sims 3/Saves/

Folder contains: [SaveName].sims3 + [SaveName].sims3.backup + [SaveName]_Export/ (travel DB). **Copy the entire `Saves` folder.**

Transfer Methods

1. Cloud Sync (Easiest): Copy `Saves` folder to OneDrive / Google Drive / Dropbox / iCloud Drive on old laptop → Wait sync → Copy from cloud to new laptop path.
2. External Drive / USB: Copy folder → Paste to new laptop path.
3. LAN Transfer: Shared folder / Warpinator / LocalSend.

Critical: Mods & Custom Content (CC)

**Saves reference Mods/CC by Instance ID.** If missing, lots/sims corrupt (bald, naked, invisible, error traps).

• Copy entire `Mods` folder: Documents\Electronic Arts\The Sims 3\Mods\ (Packages + Resource.cfg).
• Copy `DCCache` folder (Store content .ebc/.dbc): Documents\Electronic Arts\The Sims 3\DCCache\.
• Copy `WorldCaches` (if custom worlds): Documents\Electronic Arts\The Sims 3\WorldCaches\.
• Copy `InstalledWorlds` (custom worlds .world files): Documents\Electronic Arts\The Sims 3\InstalledWorlds\.

Expansion Pack Parity

New laptop **must have same EPs/SPs installed** (via Origin/EA App/Steam/Disc) **before** launching save. Missing EP → Save won't load / "Missing Content" screen.

Verify on New Laptop

1. Install Sims 3 + All EPs/SPs → Launch once → Quit (creates folder structure).
2. Paste `Saves`, `Mods`, `DCCache`, `InstalledWorlds`, `WorldCaches` into Documents\Electronic Arts\The Sims 3\.
3. Launch → Load Game → Select Save.

Tip: Run Save Game Cleaner (Batch Clean) via Mod The Sims before transfer to reduce bloat/corruption.
