What is the difference between the Eclipse Package Explorer and the Eclipse Project Explorer?

Question

It seems to me these two views are virtually identical, especially since Galileo. Is this true, or am I missing out on some features of one or the other?

Answer 1

My Project Explorer hides folders that belong to a source code management system while the Package Explorer shows e.g. the .git folder. Also, the Package Explorer offers more options that work with the source code, e.g. the refactoring stuff.
