I have loads of different SIMS3PACK files that I want to install at the same time not just double clicking on 1 by 1...is there another way of just putting them in a folder or any other way?

In order to better solve your problem, please go through the following as listed below:

  Game_Help:TS3_Custom_Content^wiki This link contains everything you've ever wanted to know about installing .package and sims3packs.
  

Look under "Installing Lots", the second section. :)

On occasion you might be asked to do a long FAQ - please make sure you do all the steps and don't just skip over them. You'll often find that these long FAQs have all the details you need.

No problem, glad you've got it worked out.
