OhRudi Updates Sims 3 Package Reducer Tool With March 2026 Patch

OhRudi released Version 2.0.0 of the Sims 3 Package Reducer (S3PR) on March 16, 2026, and the update came with a candid admission: the previous guidance on compression was wrong.

"Guy's, I made a mistake in the previous Version," OhRudi wrote in the ModTheSims forum thread. "I recommended compressing your CC, but that was just half of the truth. Compressing reduces the Package-File size, but it's no performance gain for your game, because your game has to decompresses them while playing."

The correction came directly from community feedback. OhRudi credited @CardinalSims and @swiffy for flagging the issue, which prompted the core addition in Version 2.0.0: decompression support. The updated recommendation is now to compress individual CC files while decompressing merged files, particularly those built with CC-Magic. "It's a performance gain while playing, cause your game needs them decompressed anyway," OhRudi explained.

S3PR, which OhRudi first uploaded to ModTheSims on February 25, 2026, is a utility for inspecting and reducing Sims 3 package file sizes. Its compression function uses the Sims 3 Recompressor (S3RC) by J. M. Pescado under the hood. The Version 2.0.0 zip weighs in at 42.10 MB and had logged 137 downloads at the time the page was captured.

An earlier update, Version 1.0.1 on March 6, addressed a stability issue: the tool previously failed outright when it hit an inaccessible package file. That version introduced a skip-and-report behavior, logging unreadable or unwriteable files in a summary popup rather than halting the entire process.

Version 2.0.0 also formalized a console application. S3PR.exe accepts command-line flags for recursive directory search (-r), thumbnail removal (-t), icon removal (-i), compression (-c), decompression (-d), and silent mode (-s). OhRudi notes this is aimed at players who want to automate the process, while the GUI workflow remains a two-step operation: browse to a folder of package files, check the desired options, and run. Critically, the changes are permanent and non-repeating. "You don't have to use it repeatedly," the tool documentation states. "Once you finished, you only have to do it for new Package-Files."

On the question of whether CC-Magic is required to use S3PR, OhRudi was direct: it is not. The tool processes any package file, whether it was merged with CC-Magic, assembled with s3pe, or downloaded individually. Icons are also safe to strip entirely; neither the game nor CC-Magic uses them.

The update is available across three mirrors: ModTheSims, Simblr, and SimFileShare.
