Was hoping to get some seasoned advice here. I just wiped out my xp machine and installed win7. I back everything up and iTunes was put back on and I dumped all my data back on for it. No issues. Here is what I want to know. I have a mix of music from cd's and music from iTunes (purchased). I have my music all in the music folder but it's all mixed up and I can't tell which songs are actually being used in iTunes if that makes sense. So to help things, I told iTunes to copy the file into it's own folders. Then I told it to do the new folder structure, music, movies, ringtones, etc. Anyways, it seems all is well, however I can't tell which files are purchased and which are not. If I drag a music file into iTunes, will it copy that file into iTunes and organize it? What happens if a copy already exists, will there be duplicates now? What is the best way to organize all this so I don't go insane and can clean up the mess. I am thinking of copying my backup back over to undo the recent "organization" and go from there. What do you all think? It's all kinda confusing.
