I have this MP3 file that I added to my iTunes playlist and it shows up now on my iPhone's native Music app which is all good. Since I don't really know my way around when it comes to iTunes, I have a few questions below. 1. How can I ONLY backup this one MP3 file which I have instead of backing up ALL my phone settings along with it? I only need to backup that one MP3 file and that's all. I Do NOT want to backup my whole entire phone settings, ONLY that one specific MP3 file. 2. I uninstalled iTunes from my Windows 10 machine since I now have that MP3 file on my phone and that's all I needed to be add. But lets say I wanted to perform a factory reset on my phone and during the new setup, lets say that I select to Set Up as New iPhone without choosing of course restore backup from iTunes. Is there any possible way to restore that MP3 file at a later time from iTunes within my phone without connecting to iTunes on my PC? I always select Set Up as New iPhone after doing a full reset, that's just the way I am. I like everything to be kept fresh and I don't use much apps at all, maybe like two the most. 3. I don't know what really caused this, but does iTunes tend to rearrange the columns settings in Windows file Explorer like shown in the attached image? The Downloads folder was organized as Name, Album, Artist and stuff like that...Please see image. Or, maybe I did something by mistake. Before iTunes was installed, the columns looked normal as I try to recall. The Downloads directory should of had been organized (as default) as Name, Date Modified, File Type, and Size. But ever since iTunes, it got messed up...But its all sorted now.
