I want the music and the videos that I have on the computer in different folders to automatically change when I change them in the iTunes library and I want the iTunes library to change when I change something in Windows Explorer. For example, I removed all the unnecessary comments from all mp3s on my computer in iTunes and I don't want to have to search around every folder to do it manually for every mp3, I just want them all to sync with iTunes. The same goes the other way, If I remove or rename or add a new file in my Music folders, I want iTunes to automatically update the library. I searched for an answer everywhere but all I could find required me to download some other program and it still didn't do all I wanted. I figure that there should be some simpler solution in the setting on iTunes but I just cant find it. Please help me! Thanks!
