I searched but couldn't find what i needed
 

What does removing the rats nest do and can sombody give me a link on how do do it. I found threads on it but none of the links worked.

Well some people say it does nothing, but i think mostly it just frees space, and makes everything more simple. Heres the link i used. go to the removing the rats nest section. It takes a while to load but its a goog tutorial.
