After game patches, old delta files remain. They don’t break the game but waste space. Safe to delete if game is fully updated.
The file system is inefficient — loading all DLC assets regardless of use leads to bloat. A dynamic loading system (like Skyrim ’s ESM/ESP with on-demand loading) would be far superior but would require engine rewriting.
Some advanced users merge multiple small .package files (e.g., from kits) into one to reduce file handle count. Tools like Sims 4 DLC Merger exist but risk breaking future patches. Not recommended for average users. 6. Pros and Cons of the Current DLC File System | Pros | Cons | |------|------| | Standardized .package format – easy for modders to read | No in-game DLC toggle – all files load always | | Separate folders per DLC – logical backup/restore | Bloated file count (hundreds of packages) | | Delta system allows patches without redownloading whole DLC | Delta files accumulate and confuse manual cleanup | | .ts4script enables deep mechanical expansions | Script mods conflict across DLC boundaries | 7. Verdict: A Functional but Aging System For casual players: DLC files are invisible and well-managed by EA app/Steam. No need to touch them.
The transparency of .package files is a blessing, but the lack of built-in DLC filtering is a curse. Tools like Sims 4 Studio fill the gap but shouldn’t be necessary for basic disabling.
More .package files mean more RAM consumption. Players with 8 GB RAM and all DLC often experience stuttering, especially in worlds like San Myshuno (City Living) or Brindleton Bay (Cats & Dogs).
