Recreate iTunes library on laptop and sync with iPhone
Hello. I need to recreate or rebuild my iTunes on my laptop. I have several iTunes folders in my My Music folder on my laptop. I have iTunes installed. How do I recreate iTunes?
History:
About 20 years ago I input most of my personal CDs into iTunes.
Since then I have moved iTunes to several new computers.
At some point several years ago I stopped using iTunes on my laptop and just used it on my iPhone.
Now I want to recreate iTunes on my laptop and sync it with my iPhone but I don't seem to be able to import from the various music folders into ITunes after I reinstalled iTunes.
Can all of this be done?
Thank you for any assistance or for recommending where I can find assistance.
