Thanx for the link. I appreciate the sharing of knowledge. From the beginning I was asking some questions about the organising of the thumbnails / icons but all the answers showed that the other did not understand my question. By playing and making mistakes I choose this method and I will definitely recommend it.*

Making every single package that you install into a separate runtime is well... odd.  I only know one other person who does that and that is only because of not understanding the method of setting up a runtime for a "theme" and thought that every character or clothing or texture package that is installed had to be it's own runtime.* 
Remember, I can remove a product immediately and I can find single files of a product without any hassle. I know it is not necessary this way, but for forty clothing products in one folder, for example forty products or more for V4 can create chaos again.

I can now remove a product immediately, but I can also re-install it without effort. Sometimes you download a freebie and you don't like it or it does not work and then I just remove it. When I work with WWII on a product for A3 Minnie for example I can file the converted content of coat no 12 in the same directory untill I have finished working with it and remove it, or make a backup and then remove.

Johan
