Hello, Until a short time ago i had an windows laptop that i used along with iTunes to add music libraries to my iPhone and make backups before iOS upgrades. Unfortunately i destroyed it, but I managed to save the hard drive by pulling it out and putting it in a enclosure. So, the HD is saved. Now I’m using a MBP e-08 of my friend with a fresh El Capitan installed on it. I would like to connect my iPhone, but I'm confused and terrified. I know that i can simply replace the iTunes folder of the Mac with the iTunes folder from my HD, turn off auto sync from iTunes and that’s it. But.. i’m a f****** idiot! I always had a bad management of my old computer, always moving default folders, and changing settings continuously. So, my problem is the following. C:\Users\username\My Music\iTunes\ is empty. After a long search in the HD, i discover various iTunes folders, but there's only one that seems to me to be the right one. But here lies another problem. Rummaging in folders within \ iTunes \ and specifically in Music folder, I noticed that there is only 1/10 of the music that I currently have on the iPhone. In apps folder, there are apps that were in my old iPhone and not in the current one. So, I think before my old computer died, 'Copy files to iTunes Media folder' was turned off. What is the best thing to do in this situation, losing as little as possible from iPhone? I am willing to lose my music library but not apps, settings and the rest. I’m able to enter in AppData\Roaming\Apple Computer\MobileSync\Backup\ but the last backup is 4 months ago. At the end i’m an idiot. Any suggestions would be greatly appreciated. Thank you.
