Hey, Having used windows forever, I know everything by heart from it, and where most of the files are stored etc.. However, in OS X I find myself without much knowledge concerning this. Can someone guide me a little bit, like a very rough guide (doesn't have to be much really, just to get an idea) about the folder structure on 'Macintosh HD' ? Also, for example, I have an application called Logic Pro (Logic Studio) which seems to store files in various folders on Macintosh HD, I'm not sure anymore which ones but for example it would store some stuff in 'c:/HD/applications/Logic/blablabla and then some other stuff in c:/HD/application support/blablabla Know what I mean? Why does it do this? It's not easier to store everything in one folder? Thanks!
