The more I work with iTunes, the more I am figuring out how the inner workings seem to function, but I haven't been able to find any instruction from Apple that further explains what I am wanting to know. I'lll give you a scenario to help you understand. I recently ripped an audiobook (22 CDs) and from past experience, I always check to make sure that iTunes is finding the correct info to go along with each disc prior to ripping. Durung the ripping process, I decided to check where they were getting saved to. I then realized that even though the CD info for each appeared the same, their save locations were slightly different. Upon examination, I found that some of the discs were ripped as a "compilation" and some weren't (dunno why). Well, that in itself means that all 22 CDs weren't in the root of the iTunes Library/Music folder. Granted, this isn't a big deal, just a pet peeve of mine that all the audiobook files for this book aren't together. The fix was to go into iTunes and highlight all the tracks and then go to "Get Info" > Options and change the "Compilation" option to NO. iTunes is then smart enough to move them to the same folder as the other tracks that weren't ripped as a compilation and then delete the empty folders that were left over. Thank goodness! This leads me to the question, which I'll try to make coherent. How does iTunes determine the save paths for tracks, given the criteria gathered about a CD? My example involved CDs that were thought to be a "compilation", so the tracks were put into the iTunes Library/Music/Compilations folder. Any ideas? Further clarification concerning iTunes methodology would be greatly appreciated, thanks.
