They used to bug me until I started using multiple runtimes, now I just install one file at a time, then go to that particular runtime and rename all of the newly installed folders in the Library folders so that I can easily find co-ordinating files.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
