I have kept my library on my external drobo for about two years, but due to h ow slow it is and the fact that I have upgraded my iMac driv eo a full tb, I can now move my iTunes library back onto my iMac. I have a folder titled "iTunes" on my drobo and one titled "iTunes" on my mac. When I open up the drobo file I see a lot of files, like artwork, itunes library xml, itunes music, itunes library genius itb, itunes library extras, downloads, temp file.tmp and of course my itunes music folder. When I open up the "iTunes" folder on my iMac, I see the above files along with itunes games, mobile apps and two temp files. I want all the content from my library to now appear on my iMac, what do I need to move and what do I need to replace?
