The Sims 3 Package Explorer, created by Okeanos, a Sim citizen of the customsims3 community, is a tool to examine, extract, replace and modify Sims 3 package content. The current version 1.1.0. is available at the rapidshare website.

The tool is written in Microsoft .NET Framework 3.5 under C#. It is a windows tool and should be able to do roughly the same as postal.
