Why dont i have an editor folder in my project window?

Following a tutorial

he imported the standard assets by downloading them from unity web site
i couldnt find the same place, although i did find additional windows downloads but it didnt have the standard assets it had three other options.

I managed to import the standard assets into my project through the store though

but if i go
Assets → import package there is nothing but custom package, is that because i have already imported everything?

but why dont i have the editor folder in my project? it seems important.

Because you don’t use the same Unity version as the tutorial. Things changed since then.

thanks ninja
