Hi, I have a few questions about my music folder, and to save time and space I'll just put them in one thread. In the album artwork folder of my iTunes music folder, I have three folders called - Cache, Download, and Local. Why are these folders separate? And Can I just put the contents all in one folder? Or do they need to be separated? Secondly in my iTunes folder there are numerous folder called iTunes Library? Do I need to keep or those files and folders or can I delete them? It looks a bit like this except there's more within the highlighted folder.
