Before You Download
Please read these important notes.
Generally, we recommend you grab unofficial parts one-by-one, and use them for only for a specific project. If you are using MLCad, you can import the unofficial part(s) as submodels into your main model files and save them in a .mpd file. That way, if changes are made to the unofficial parts before they are officially released, your model won't be adversely affected.
But, if you're impatient, sure you want all of the unofficial parts and are willing to take your chances, you can download all of the unofficial parts at once.
You will need to clean up at a later time. The best (that is, the safest) way to install these files is to unzip them to a temporary directory. A short tutorial how to add them for example to MLCad can be found at: http://www.holly-wood.it/mlcad/customizing-en.html#scan. Don't simply dump them into your LDraw\parts directory, it would be very hard to sort them out of there later.
When you unzip the files, be sure to tell your ZIP tool to use the folder names, so all the files will end up in their proper subdirectory.
