Simple iTunes Question

Dtc's answer is more to the point if you want iTunes to keep track of your library with minimal problems. I've found dragging and dropping stuff and then telling iTunes to find it can lead to some potential problems, especially if you just isolate the music folders and do a drag-drop. You're potential for problems is worse if you are moving WAV files as iTunes carries all the tags for those files within other files and links to them in a different way than the meta-tags used for other codecs (this is how I understand it and I have run into problems moving WAV files around). Do the copying and changing within iTunes to reduce your headaches - that's been my experience at least. Good luck.
