I used this and nothing appears in my game! Select the folder where you want to extract the files to using the second 'browse' button. Select the folder with all your Sims3Pack files using the first 'browse' button.
No testing has been performed on Vista or XP 圆4. It has been writted and tested on Vista x32. It is PURELY meant to extract Sims3Packs so that you may put them in your Mods\Packages folder, or subfolders thereof. It will NOT give extracted packages the custom content icon. Please note! This is NOT a replacement for the Launcher. This program (Similar to my Sims2Pack Multi-Installer) allows you to bulk extract multiple Sims 3 Pack files in a folder, extracting them to another folder (it doesn't have to be Mods\Packages, it could be a staging area).
